Day-Ahead Reactive Power Scheduling for Distribution Network Considering Coordination of Distributed Generation With Capacitors
摘要
Abstract
In allusion to the situation that in present distribution networks containing distributed generation (DG) the coordinated dispatching of the compensating capacity of capacitors with reactive output of DG is not taken into account, a reactive power optimization method considering the coordination of capacitor banks with DG is researched. Taking the highest satisfaction degree of both network loss and voltage deviation as the objective, an optimal day-ahead dynamic reactive power scheduling model for distribution network containing DG is constructed. Based on the reactive power output of DG and the features of capacitor compensation, a day-ahead reactive power scheduling that coordinates the DG with capacitor banks is proposed. Firstly, the limits of various DG’s reactive power output are analyzed and taken as constraints, the overall static state optimization of DG and capacitor banks is performed to attain the switching on/off capacity curve of capacitor banks; then fuzzy clustering is adapted to segment the capacity curve and subsection integration is used to formulate the day ahead schedule of capacitors;finally, after the determination of the compensating capacity of capacitor banks, the day-ahead scheduling of DG is drafted. Simulation results show that the proposed method is effective.关键词
