Study on the Whole Life Cycle Energy Management Method of Energy Storage System with Risk Correction Control

Abstract

With the rapid development of energy storage technology, more and more energy storage systems are connected to the large power grid. Therefore, how to improve the safety, reliability and stability of the grid-connected operation of energy storage power stations is the most important. Based on this background, this paper proposes the research on energy management and control methods of large-scale energy storage power station. First of all, the operating cost model of the energy storage system is established by comprehensively considering its life-cycle operation characteristics. Secondly, according to the spatial and temporal distribution characteristics of distributed power supply and load, the energy storage regulation technology based on dynamic safety margin is proposed. Finally, according to the set dynamic safety margin of energy storage system, the energy management method of energy storage power station based on risk correction control is proposed. An example is given to verify that the energy management method proposed in this paper has the following characteristics: it can effectively evaluate the system energy supply sufficiency and realize the accuracy of system regulation.
