DERMS Volt-Var Control of a Power Distribution System Using Clusters of Building Multi-type Air-conditioners

抄録

This paper proposes a new method of Distributed Energy Resource Management System (DERMS) Volt-Var droop curve control for electric power distribution systems using reactive power demand response, which we call VarDR. The DERMS aggregates the droop-curve-designated reactive power from a cluster of dozens of air-conditioners in neighboring buildings near the location of a problem in the distribution system. Computer simulations using a VarDR DERMS were carried out using a model scenario with large PVs, extremely fast-charging EV stands, and battery energy storage systems (BESSs). The VarDR DERMS droop curve control showed stable recovery from transient over/under voltages without significantly degrading the air-conditioning performance.
