Coordination and Optimization for Reactive Power Voltage of Power Distribution Network Under New Energy Environment
摘要
Abstract
By using the method combining the optimization strategies for reactive power of distributed generation (DG)and traditional reactive power,this paper discusses coordination and optimization for reactive power voltage of the power distri-bution network with electric vehicles (EVs)and energy storage system (ESS),and analyzes effect of ESS in improving ab-sorption ability of new energy generation and stabilizing voltage deviation. Considering randomness of DG and EV,it uses the point estimation method for probabilistic load flow (PLF)calculation and establishment of the coordination and optimi-zation model of reactive power of the power distribution network aiming at average deviation of node voltage expectation and the minimum of network loss expectation. It also adopts the animal migration optimization (AMO)method to solve the multi-objective optimization model and acquire a group of noninferior solution set for decision-makers choosing. Finally,it makes use of IEEE 33 node system for simulating analysis and compares with particle swarm algorithm so as to verify effec-tiveness of the model and the accepted algorithm.关键词
