A distributed real time power allocation strategy for dispersed energy storage systems

This paper presents a distributed consensus strategy that regulates the power outputs of dispersed energy storage systems (DESS) in power distribution network, which can be used to smooth the renewable power fluctuations. The algorithm is based on the consensus algorithm in graph theory and it satisfies both the smooth of the renewable power fluctuations and the equity allocation among DESS. The most distinct feature of the algorithm is that there is no "dispatch center" or "leader" to collect the global information in real-time power allocation process, each DESS obtains the global information and allocates its power outputs and realizes the target of smoothing the global renewable power fluctuations according to the local information interaction among DESS. Simulation on the IEEE 34-bus distribution system demonstrates the effectiveness of the proposed algorithm.
