Abstract

Based on the typical radial distribution network structure, the paper firstly deduces the voltage - active expression of the distribution network based on the voltage sensitivity, based on which, a distributed PV active and reactive power coordination control method based on the voltage sensitivity matrix is proposed. Simulation results show that the proposed voltage control method can effectively solve the voltage crossing problem of the distribution network, fully utilize the reactive power output capability of distributed PV, and at the same time, make all distributed PV on the same feeder share the active power reduction and share the power generation loss caused by the participation in voltage regulation.
