Abstract

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.
