    Recently, an installation of photovoltaic (PV) power generation in power distribution systems has been paid attention to around the world. Nevertheless, the PV generation may cause a reverse power flow which results in the voltage rise problem. To tackle this problem, the battery energy storage can be applied. However, the optimal placement and capacity of battery are very important issue to be considered due to the high cost of battery. This paper applies the bee colony optimization to determining the optimal location and size of battery. Simulation results with many scenarios confirm the control effect of battery optimized by the proposed method. © 2013 ICIC International.

    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.
