Abstract
Day by day energy crisis and environmental issues are increasing. The most effective solution for these issues is the use of renewable energy sources (wind, solar etc.) in distribution networks (DN). However these have some disadvantages and one among them is uncertainty in nature. So it’s difficult to utilize the full potential of renewable energy sources. By using battery storage systems (BSSs) this problem can be avoided. In this paper, an optimal power flow (OPF) is formulated, for the spilled energy calculation. For maximum utilization of spilled energy BSS needs to be properly sized and here, it is done by a nonlinear programming (NLP) technique. Also, maximum potential of BSSs can be exploited by providing both active and reactive power from BSS to the network. The methodology is applied to a 47 bus Indian distribution system and results demonstrate that, there is a significant reduction in energy supplied by the grid and losses due to the integration of BSS. In this work it is assumed that wind generators are integrated into the network.
