Optimized Fuzzy Control Algorithm in Integration of Energy Storage in Distribution Grids

AbstractThis paper presents the incorporation of energy storage system (ESS) in smart distribution systems so that the total payment of the system is minimized along with compliance of the system constraint including voltage limit in the system's steady state. Fuzzy control and particle swarm optimization (PSO) algorithm are employed to acquire the charge/discharge mode and the amount of energy in storage system in each hour of a day using online pricing. The storage system is allocated in such a way that system constraint including voltage not violated in system's steady state condition. So that a distribution load flow in backward/forward load sweep method is used to restrict the voltages in limit. Finally the profile of charge/discharge storage system considering bus voltage deviation limit is illustrated
