Research and Simulation Analysis on Scheduling Strategy of Distributed Energy Storage Systemes
In order to improve the operation efficiency and power system stability of distributed energy storage system, this paper proposes a scheduling strategy based on sensitivity analysis. Firstly, the sensitivity matrix between the energy storage bus phase angle and the system bus phase angle, the energy storage bus voltage and the system bus voltage is derived according to the power flow iteration equation of the fast decomposition method; secondly, the sensitivity coefficient is modified based on the consideration of the overcharge and overdischarge of the energy storage battery, and the sensitivity coefficient is sequenced to get the optimal scheduling scheme; finally, the PSASP simulation software is applied The simulation results show that the frequency smoothing rate and voltage smoothing rate of the scheduling scheme based on sensitivity analysis are higher than those of the comparison scheme, and the optimal scheduling scheme based on sensitivity analysis is verified.
