基于分布式供能系统功率互动能力的双目标电压协调控制策略
Double-objective Coordination Control Strategy for Voltage Considering Interactive Capability from Distributed Energy System
摘要
Abstract
Considering that intermittent distributed generations(DGs)have strong volatility and randomness,their inte-gration to the end of a weak distribution network will form a fragile electrical connection between the source and net-work,which causes obvious voltage fluctuations at the connection points and thus affects the electricity quality. In order to solve this problem,a double-objective coordination control strategy for voltage is proposed considering the interactive capability of distributed energy system(DES). Based on the control characteristics of different units in DES,the termi-nal voltage fluctuations of upstream weak distribution system are solved through the optimal scheduling of multiple ener-gies,such as cooling,heating and power. Simulation results of a typical numerical example show that the proposed method can not only restrain the voltage fluctuations at the connection points,but also reduce the operation cost of DES.关键词
