Research on Coordinated Optimization Strategy for Multi-Region Emergency Load Shedding

Abstract

Load reduction control is an important technical measure to deal with the serious fault and emergency state of power grid, and it is also one of the important technical means to ensure the safe and stable operation of large power grid. This paper proposes a coordinated optimization strategy for multi-region emergency load reduction that takes the safety and stability of power grid and accident risk into account. By taking the cost of regional load reduction proportion into account, the coordinated optimization of multi-region load reduction control measures is realized, and the problem of excessive load reduction control in some regions caused by the lack of coordination of load reduction objects among multiple regions is solved. The case analysis results show that the proposed strategy can effectively guarantee the safety of power grid and reduce the control cost and the risk of safety accidents.
