Intelligent Control Strategy for Energy Storage in Distribution Systems

With the rapid development of energy storage technologies, there is a growing interest in integrating these devices into distribution systems. Energy storage can be utilized to provide various benefits to the distribution systems. In this paper, the reliability and economic benefits (i.e. energy cost) are the focus. Different control strategies of energy storage have corresponding reliability and economic impacts on the systems. An intelligent Model Predictive Control (MPC)-based control strategy for energy storage is first introduced and compared with a conventional standby backup control strategy. Then a modified MPC-based control strategy is proposed to more effectively utilize limited energy storage capacity to improve system reliability and save energy cost. Simulation results are shown to illustrate different control strategies and demonstrate benefits.
