This paper presents a load frequency control (LFC) of five areas connected to same tie-line and it consists of non-conventional main power grids (Thermal–Hydro) and micro-grids (Wind-Diesel). Performance of conventional PI controllers is compared with PSO (Particle Swarm Optimization) tuned PI controller in a regulated and deregulated environment. A five area power system model has been made using Matlab/simulink to analyze load frequency control measures under different conditions based on participation factors, load disturbances and variations in local load demands. Simulation results shows that PSO (Particle Swarm Optimization) tuned PI (Proportional & Integral) controller's gains give much better performance than the conventional PI controller parameters which are more difficult to determine and time-consuming. The effect of DFIG (Doubly fed Induction Generator) in the power system which helps to smooth the tie line power is also been described. Keywords: PSO, PID controller, LFC, Regulated and Deregulated.

The thermophotovoltaic cells are operating in the infrared and the far infrared wavelength region. In the automobile sectors the conventional fuel is consumed by the engine to aid the movement of the piston which in turn is coupled with a wheel for movement of the vehicle. The engine is heated up during the burning of conventional fuel and the heat is extracted for efficient operation of the engine through a radiating device. A coolant is flowing through a pump to keep the radiator in cooling condition for maintaining the engine efficiency and ensuring safety and protection of the engine. The heat lost from the radiator can be classified as dissipated heat which can be utilized in many purposes. The modern thermophotovoltaic cells can use this waste heat to generate electrical power to charge the battery and effectively reduce the load on the dynamo. In the present paper a study has been conducted using Sims cape™ in MATLAB R2012a to find out the impact of thermophotovoltaic cells in reducing the fuel consumption in a conventional quasi-flow engine. The simulation showed that the proper coupling of the thermophotovoltaic cell can serve as a substitute power source of the coolant pump and therefore it reduces power consumption of the battery. The results

123



showed that a total heat dissipation of 43157 Watts can be used to run the pump at about 4000 revolutions per minute and the corresponding piston temperature is about 335.6 K. The details of the studies and the simulation methodology have been presented in this paper.Keywords: Thermophotovoltaic cells, dissipated heat, coolant pump, piston temperature.

The Electrocardiogram (ECG) is a sensitive diagnostic tool that is used to detect various cardio-vascular diseases by measuring and recording the electrical activity of the heart in exquisite detail. Identification of QRS-complexes in ECGs has been a challenging task ever since the beginning of automated ECG analysis. The identification of QRS-complexes using LS-SVM as classifier has been presented in the paper. Since slope of the ECG is much more in QRS region as compared to other region, it has been used as an important discriminating feature. Using LS-SVM as a classifier, the QRS-complexes have been identified with an accuracy of 99.51 % with 0.49% of false negative (FN) and 0.25% of false positive (FP) respectively. The QRS-complexes have also been delineated with the tolerance limit as specified by CSE. Keywords: QRS Complex, Slope, LS-SVM, SVM.

Hybrid contactor is a switching device, which while making & breaking an electrical circuit do not draw any arc between its cathode & anode electrode. This is achieved since the making & breaking of the load is done by the solid state device and rated current is carried by the electromechanical contactor. The starting current & its duration being very high for any load, it needs special functionalities for healthy operation of the device. The paper reveals about an intelligent µC programme, which provide a delay between the operation of the solid state device & contactor so as to inhibit high starting current to flow through the contactor & avoid arcing. Also it senses the magnetic field and ambient temperature to overcome the magnetostriction effect upon electromagnet and heating of the SCR. The functionality of the programme is evaluated by means of testing a 32 A hybrid contactor. The test result reveals that during making & breaking operation, there is no arc produced and successfully operated the intended sequence & logic, as per the instruction fed to the programme.Keywords: arcing, hybrid contactor, self commutation, µC, NTC, ADC, IC, bit architecture, peripherals, Watchdog timer, DTC, multiplexer, EM, SCR.

Evolvable Hardware (EHW) refers to hardware that can change its architecture and behavior dynamically and autonomously by interacting with its environment. This paper presents a new approach to on-line fault tolerance via reconfiguration of the Programmable Elements (PE) mapped onto field programmable gate arrays (FPGAs). A grid of PE is programmed on the FPGA structure. A complete hardware implementation of an evolvable combinational unit for FPGAs is then performed. The proposed combinational PE grid on FPGA is used as virtual reconfigurable circuit (VRC). Cartesian Genetic Programming (CGP), genetic operators are described in Verilog - HDL and used to reprogram the VRC. In all the cases the unit is able to evolve (i.e. to design) the required function automatically and autonomously, with a maximum delay of 22.82ns (when logic level is 16) which is 40% lower than previous attempts. The design parameters of the proposed architecture are also discussed. The fault detection, based on self-checking technique can detect the faults of PEs and routing interconnections in the FPGAs concurrently with the normal system work. After locating the faulty PE, the VRC will be reconfigured using reserved PEs.Keywords: EHW, Fault detection, FPGA, PE, Reconfiguration, VRC, CGP.

Impending Smart Grid environment can offer innovative solutions to alleviate network congestion through efficient network management. This paper proposes a coincident demand based Smart Long Run Incremental Cost (LRIC) pricing mechanism to provide efficient pricing signal to users for mitigating network congestion. Considering that future smart meters would measure user's coincident peak demand, the user is offered a coincident demand based Smart Pricing signal in a LRIC pricing framework. The proposed approach is applied on 22-bus practical Indian reference network. Users connected at the various nodes face network charges based on their coincident demand to each upstream asset. The results encourage users to modify their consumption pattern, and reduce their coincidence to network peak usage. Keywords: coincidence factor, LRIC, network pricing, smart grid.

Email: [email protected]

There are numerous simulation tools for studying electrical and electronic circuit system dynamics. Most of the times, we stick to a specific software package for studying the behavior of a circuit- it depends either on acquaintance with the software or on accessibility. However, it is good to carefully evaluate the advantages and shortcomings of each package prior to selecting one for a given set of objectives. In this paper, it has been demonstrated how one can combine both the popular simulation tools MATLAB/SIMULINK and PSPICE to study the dynamics of the dc-dc converters. The introduced co-simulation method has advantages like elimination of the laborious process of development of transfer function of the power stage for designing the controller, get rid of convergence problem and truncation of simulation time. The method proposed can be adapted by beginners who are very new to the designing of switching regulators for the quick understanding of dynamics of the converter. Down converter with voltage mode control is used to verify the proposed method. This can also be extended to higher order converters, like Cuk and SEPIC, where deriving the transfer function of a plant is quite tedious process, apart from above mentioned second order converter. Also, simulation with idealized models and detailed models has been discussed in the paper.Keywords: down converter, higher order converters, TL494, MATLAB/SIMULINK, PSPICE, SISOTOOL.

Over these years, dependency of electric generation on renewable is increasing steadily. The renewable energy sources are usually connected to the electric grid on the distribution networks. Energy supply from prominent renewable sources like wind and solar are restricted due to the high level of unpredictability and intermittency associated with them. This leads to the inefficient and less reliable output from these sources. Thus proper generation prediction, sizing and intermittency mitigation of renewable energy sources such as wind and solar photovoltaic (PV) is necessary while placing them on the feeder. As these sources are distributed energy sources, the loss minimization can be one of the opportunities in addition to their generation support. This paper deals with the optimal sizing of solar PV and battery combination in a grid connected system. Solar PV generation is seen as the future generation source and battery storage with its matured technology can support it to become more reliable source in a power system. Here an analytical method for sizing of solar PV and battery is proposed. The line losses and intermittency minimization is the prime consideration for the sizing and placement of the solar PV and battery. To tackle with the variability of the solar PV generation, it is predicted by probability density function and supported by battery energy storage. The battery energy storage is properly sized to satisfy the state of charge limitations. The location and sizing methodology is applied to a 13-bus test system using MATLAB. With the proposed optimal sizing methodology the losses can be reduced up to 83 % during the solar PV generation period and a small amount of battery support can help to get constant power supply to the grid from the solar PV.Keywords: Solar PV generation, beta probability density function, PV sizing, battery storage, State of charge, line loss reduction.

Spacecraft Bus is regulated with switching shunt voltage regulator having photovoltaic cells as the primary source of power. This source switches between the bus loads and the shunt switch for fine control of spacecraft bus voltage. The solar cell capacitance along with inductance and resistance of the interface cable between solar cells and power conditioning unit, generates damped sinusoidal currents superimposed on the short circuit current of solar cell when shunted through switch. The peak currents of sinusoidal transients have to be considered in the selection of shunt switch in power conditioning unit. Solar Panel is a combination of series and parallel solar cells forming many strings. Hardware simulation by illuminating solar panel interfaced to a power condition unit with actual spacecraft cable length is a difficult approach. In view of this a scaled down version of solar panel (having single parallel) is illuminated with known interface cable length. This hardware simulation provides sufficient information to generate solar cell model to carry out software simulation and analyze current transients of shunt switch for the actual solar string rating. Keywords: Shunt regulator, Shunt switch, Current transients, power conditioning unit.

The chosen control algorithm includes three different approaches-equal current, equal power and modified equal current. The above said criteria are compared graphically and analytically for unbalanced and non-linear load condition. Results obtained show that modified equal current approach is more effective than the other two even if the source voltages are severely distorted and unbalanced. For realization, an extensive digital simulation is done using MATLAB environment.

The emerging trend of restructuring power systems, security is becoming a major concern for electric utilities. The security assessment of power system is being considered as an important problem in planning, operation and control. Security assessment entails that the system should remain in secure operating state under abnormal conditions. In a power system the Security assessment is carried out by using the voltage performance index (VPI) following a contingency. Contingencies are termed as the uncertain events, occurred due to line outage in the system. VPI can be used for identifying the critical contingency from the perspective of bus voltage violation limits. Flexible Alternating Current Transmission Systems (FACTS) devices are having a great impact on the performance of the transmission network. FACTS devices are used for controlling real and reactive power flows and regulating the bus voltages in power systems. Also, FACTS devices raises power transfer capability reduces system losses and improves system stability, because of their fast and flexible control characteristics. Owing to their huge capital cost, it is essential to place these devices optimally in a power system. In this paper, Differential Evolution (DE), a population based stochastic meta-heuristic optimization algorithm is applied for optimal placement of static var compensator (SVC) aimed to the voltage security enhancement of a power system. The SVC placement is considered to be a planning problem and is formulated as a multi-criteria problem comprising of minimization of real power loss, voltage security and investment cost of SVC under single line outage contingencies. Effectiveness of the DE algorithm based approach has been demonstrated on IEEE 30-bus test system.

Particle swarm optimization (PSO) algorithm is applied to find optimal dispatch for minimizing cost and maximizing profit of conventional units integrated with renewable power. Non-conventional energy sources, such as wind, are highly uncertain in nature. Generation of wind power depends on the wind speed. The uncertainty of wind power in cost model is considered by taking a dynamic dispatch model. This paper considers six conventional thermal generator units taken from IEEE 118-bus test system with wind turbines. The model includes all practical constraints like ramp rate limits and valve point loading effects of thermal generating units. Min-max limits are modified by ramp rate limits of generating systems. Optimization problem includes practical constraints with non-linearity and non-convexity. For convex cost case, the results are validated using the sequential quadratic programming (SQP) algorithm but unfortunately, the conventional gradient based optimization methods are unsuitable for non-convex cases. On the other hand the swarm intelligence based models guarantee stable convergence to near best solution for such cases. Keywords: Dynamic wind-thermal optimal dispatch, Profit maximization, valve point loading, ramp rate limits, PSO, SQP.

In the conventional two degree of freedom (TDF)-internal model controller (IMC) design, obtaining the optimal value of tuning parameter is much more difficult task. In most of the cases either formula based conventional techniques or trial and error based approaches have been suggested. In this paper, the approach of genetic algorithm (GA) is proposed to obtain optimized value of tuning parameter used in TDF-IMC controller design. The different second-order reduced-models, (which are considered as internal/predictive models for TDF-IMC structure) using different model reduction techniques are intentionally derived to perform a comparative study. The applicability of the proposed technique has been illustrated with the help of a numerical example. The simulation results clearly indicate much improvement in the response of load frequency control (LFC) during load disturbance and in the presence of uncertainties, over some other existing results.

A simplified space vector approach based active zero state pulse width modulation (AZSPWM) algorithms are presented for vector controlled induction motor drive to reduce the common mode voltage variations. The space vector PWM (SVPWM) algorithms divides the zero state time equally between the two zero states. Because of the usage of zero states, the SVPWM algorithm gives large variations of common mode voltage. Moreover, as the classical space vector approach requires the angle information, the complexity involved is more. Hence, to reduce the complexity, the proposed approach calculates the switching times from the instantaneous phase voltages only. Also, in order to reduce the common mode voltage (CMV) variations, the proposed algorithms did not use the zero states.

This paper presents simplified scalar based pulse width modulation (PWM) algorithms for the reduction of common mode voltage. Though, the space vector PWM (SVPWM) algorithm gives superior waveform quality, it results in large common mode voltage variations due to the usage of zero voltage vectors. Moreover, the complexity involved in the classical space vector approach is more due to the calculations of angle and sector information. Hence, to reduce the complexity and common mode voltage (CMV) variations, the proposed approach calculates the gating times by using the instantaneous phase voltages only. In the proposed approach, by adding a unique zero sequence signal to the phase voltages, the modulating signals are derived. Then, by comparing the modulating signals with triangular signals, the gating pulses for the various PWM algorithms are derived. As, the proposed PWM algorithms did not use the zero states, these results in reduced common mode voltage variations. To verify the proposed PWM algorithms, numerical simulation studies have been carried out on scalar controlled induction motor drive.

This paper describes combined discrete wavelet transform (DWT) and Naive Bayes (NB) fault classifier for protection of double circuit transmission line. Three phase currents of both circuits and zero sequence current are given as input to the NB network for classification of fault. Inputs are pre-processed using approximate coefficient of DWT. NB classifier uses Gaussian distribution function for classification. Seven classifiers are designed for fault classification for each phase A1, B1, C1, A2, B2, C2 and ground G. Advantage of using Naive Bayes classifier is that it takes few seconds for training no matter how big the data is. Different cases of fault are studied like phase faults, phase to ground faults, inter-circuit faults, cross country faults, fault near boundaries, different fault location, different inception angle and different fault resistance with high fault resistance. Accuracy of the proposed method is 99% and reach setting is also 99% of line length.Keywords: DWT, Fault Classification, Faulty phase Identification, Naive Bayes Classifier, Reach setting.

This paper deals with active resonance damping of LCL-filter-based DSTATCOM with reduced number of sensors, which can effectively compensate non-linear load harmonics, reactive, negative sequence current and neutral current in three phase four wire distribution system. With an LCL-filter, Additional switching frequency current components can be reduced more effectively. However, because of the resonance phenomenon of the supply filter and the DSTATCOM wide operating bandwidth, the use of the LCL filter in DSTATCOM is challenging.

generalized PWM algorithm the actual gating times are generated from the instantaneous sampled reference phase voltages only. In this algorithm, a unified expression is derived for offset time from which by varying a parameter various PWM algorithms can be generated. Further, the proposed HPPWM algorithm has been developed based on the mean square current ripple characteristics. This algorithm uses the sequence which results in reduced harmonic distortion in current over a sub cycle and hence it improves the performance of the drive system.

Orthogonal Frequency Division Multiple Access (OFDMA) has become the key physical layer technology for all future wireless standards including LTE, because of its high spectral efficiency and its capacity to combat multipath fading. In spite of its advantages, one of the major drawbacks of OFDMA system is its high Peak to Average Power Ratio (PAPR) value which is directly related to power consumption of the system. Although power consumption is not a problem for downlink channel, it is one of the main issues for uplink channel because the available power for the mobile user is limited. To overcome this issue, in LTE, for the uplink channel, Discrete Fourier Transform (DFT) spread OFDMA or Single Carrier-FDMA (SCFDMA) system is used. In this paper, we intend to analyze PAPR variation by varying critical parameters of LTE baseband such as number of subcarriers and different modulation and coding schemes. We also examine the power savings and their tradeoffs for resource mapping schemes such as OFDMA, Localized SCFDMA (LFDMA) and Interleaved SCFDMA (IFDMA).Keywords: PAPR, OFDMA, SCFDMA, LTE, IFDMA, etc.
