Bee colony optimization of battery capacity and placement for mitigation of voltage rise by PV in radial distribution network

Abstract

At present, the penetration of photovoltaic (PV) power generation in the distribution network tends to increase considerably. However, when the PV sources are located at the ending bus of the radial network, they may cause a reverse power flow and a voltage rise problem. To reduce the voltage rise, the battery energy storage can be used. Nevertheless, the inevitable problem of battery is the high installation cost. The optimal placement and capacity of battery are the vital issue to be considered. In this paper, the bee colony optimization is applied to find the optimal placement and capacity of battery in the radial distribution network for alleviating the voltage rise due to PV sources. Simulation results under several scenarios indicate the superior control effect of the optimized battery over the non-optimal battery. © 2012 IEEE.
