面向配电系统灵活性提升的多微电网分布鲁棒协同优化调度OA

With the increasing penetration of distributed renewable energy,the operational flexibility of the new distribution system is facing challenges.Therefore,a coordinated optimal scheduling model of the distribution system operator(DSO)and multi-microgrids(MMGs)is proposed for improving the distribution system's flexibility.Firstly,a flexible ramp product(FRP)trading mechanism between DSO and MMGs is proposed based on the distribution network market.Secondly,the uncertain fuzzy set of renewable energy prediction error based on Wasserstein distance is constructed,and the day-ahead and intra-day two-stage distribution robust optimal scheduling model of the distribution network and microgrid considering FRP is established.The affine strategy and strong duality principle are transformed into a mixed integer linear programming model for solution.Furthermore,a fast alternating direction multiplier method based on predictor-corrector decouples the tie-line power between DSO and MMGs.Finally,the validity of the proposed model is verified by a modified IEEE 33-bus distribution system.The example results show that the proposed scheduling model can effectively improve operational flexibility within the multi-microgrid distribution system.
