The Emerging Smart Distribution Grid presents an increasingly complex system to manage

• Distribution Operators still have their hands full safely coordinating crews doing switching and restoration – keeping the lights on with no time for “advanced functions”

• Distribution Analysts may work with advanced functions to maximize system and energy efficiency, often via automated systems like FLISR and IVVO

• Still others may coordinate demand response participants, distributed energy producers, and manage AMI/MDM

• In smaller utilities, Operators may do it all!

• Increasingly mobile users need to interact remotely

• A comprehensive network management system improves efficiency of users, safety, and system support

Operations Department Focus

With proper evaluation tools, Operations can:

• Prepare operational mitigation procedures

• Restrict DG connection permits granted

• Request engineering design remediation

• Build regulatory cases for more operationally restrictive DG connection contracts

IDMS and Smart Inverters

• Ongoing DOE sponsored project with Duke Energy and NREL leveraging the ESIF

• Evaluate capabilities of commercially available “Smart” Inverters and their impact on distribution operations

• Add Smart Inverter set points as a control type within IVVO to complement taps and capacitors

• Controlling Smart Inverters is key for a DER enabled ADMS - DER voltage rise, backfeed, power factor control

The Evolving Sophistication of Emergency Load Reduction

• Demand Minimization with IVVO

• No customer impact – voltages moved to low end of normal ANSI range

• Demand Response program calls

• Commercial and residential DR participants

• Emergency Demand Minimization with IVVO

• Voltages moved to the next lower ANSI range

• Surgical Load Reduction by network optimization function

• Selective load curtailment via AMI disconnects with customer type and DG awareness

• Educated Load Reduction through circuit switching by network optimization function

• Based upon As-Operated network model with critical customer awareness

• Rotational Load Shed through classic SCADA-style function

• With abnormal configuration and critical customer awareness

• Traditional Block Load Shed

Utility customers are asking for a stepped approach to load reduction orchestrated through IDMS. Generally:
