基于产消方式的互联微网协同自治运行策略
Prosumer-based Autonomous-Synergetic Operation Strategy for Interconnected Microgrids
摘要
Abstract
With the increasing penetration of distributed generators on the demand side, the dispatch problem among interconnected microgrids (MGs) is difficult to solve by directly optimizing its non-cooperative features.In view of this,this paper proposes a prosumer-based autonomous-synergetic operation strategy for interconnected MGs by integrating the bilateral trade mechanism of electricity market.With full respect for the obj ective law of market operation,this strategy can provide a reference for economical dispatch of distribution networks by mining the essence of power transaction and active energy management.A two-level optimization algorithm is designed to realize the strategy,in the lower level of which,the local marginal price and supply/demand curves of autonomous MGs are calculated to seek the equilibrium point of synergetic operation of interconnected MGs.In the upper-level,the primal-dual interior-point method is employed to optimize the inj ection power of MGs and tie-line power.Simulation results show the correctness of the strategy proposed and its effectiveness of application in the real-time optimization dispatch of an active distribution network.关键词
