计及多重不确定性与综合贡献率的多微网合作运行策略

COOPERATIVE OPERATION STRATEGY OF MULTI-MICROGRIDS BASED ON MULTIPLE UNCERTAINTIES AND COMPREHEN SIVE CONTRIBUTION RATE

针对多微网系统如何实现各微网利益公平分配的问题,提出一种考虑多重不确定性和综合贡献率的多微电网合作运行策略。首先,采用鲁棒优化和信息间隙决策理论分别处理电价和风光不确定性,以降低系统的运营风险;并引入消纳责任权重促进可再生能源的消纳和系统的绿色、经济运行;然后,以基于非线性能量共享映射法的能量交互贡献率和二氧化碳排放减少率来量化合作贡献,实现利润分配的公平性以及促进各微网低碳减排的积极性;最后,基于Matlab平台对多微电网进行仿真模拟和算例分析,验证所提策略的合理性和有效性。

How to achieve fair distribution of benefits among microgrids in a multi-microgrid system is an urgent issue to consider.This paper proposes a cooperative operation strategy of multi-microgrid considering multiple uncertainties and comprehensive contribution rate.Firstly,robust optimization and information gap decision theory are used to deal with electricity price and wind-solar uncertainty respectively to reduce the operational risk of the system.The weight of consumption responsibility is introduced to promote the consumption of renewable energy and the green and economic operation of the system;Secondly,the energy interaction contribution rate and carbon dioxide emission reduction rate based on the nonlinear energy sharing mapping method are used to quantify the cooperative contribution,so as to realize the fairness of profit distribution and promote the enthusiasm of low-carbon emission reduction of each microgrid.Finally,based on the Matlab platform,the simulation and case analysis of multi-microgrid are carried out,which verifies the rationality and effectiveness of the proposed strategy.
