Evolutions in the grid
• Increased share of intermittent renewables• Stabilization/decrease controllable production• Electrification of transport and heating

Linear situated⇒ Energy excesses and shortages⇒ Grid capacity issues
⇒ storage⇒ “consumption follows production” (i.e., demand response)

Classical control paradigm“production follows consumption”
no longer holds
Linear focuses onResidential Demand Response

Wind balancing
• Flexibility can be used by the BRP as an alternative for gas power plants• The exact economic benefit is dependent on the amount of flexible consumption
K. Kessels et al.: Feasibility of employing Domestic Active Demand For Balancing Wind Power Generation
Other research results
• Battery storage systems as an alternative to demand response
• Electric Vehicle charging coordination schemes
• Combined Heat and Power as a bridge between electricity and gas grids

J. Vandewalle et al. : The Role of Thermal Storage and Natural Gas in a Smart Energy System
Conclusions
• A realistic simulation environment was created to test the potential of different smart grid solutions
• Transformer ageing can only be improved by demand response if the peak load is sufficiently high compared to the rated load
• Improvement in the line voltage is possible with demand response and batterystorage
• Results are highly feeder-dependent
• Significant benefits can be achieved for consumers who can shift their consumptionin time, mainly for the large consumers such as EV and DHW
• Combination of portfolio management and voltage control does not significantlyimpact the business case
• Significant benefits can be achieved for the BRP when using demand response forbalancing its portfolio
