Research on the Mathematical Model Construction and Algorithm of Dynamic Reactive Power Optimization about Distribution Network

Abstract

Dynamic reactive power optimization of power system is an important means to ensure grid economic safety. Unlike static reactive power optimization, dynamic reactive power optimization has to consider the reactive power compensation devices switches and number of constraints of transformer tap stalls. The number of constraints undermine the independence of each period, each time reactive power optimization scheduling interrelated, so dynamic reactive power optimization must be considered from the entire period of time to compensate the number of constraints of the devices, and how to deal with action number of constraints is difficulty and focus of solving dynamic reactive power optimization of the power system.
