摘　　要：针对含灵活性资源的多微网配电系统,提出一种基于动态非合作博弈的多微网配电系统定价策略,以引导用户侧调整用电方式实现系统经济运行。提出一种双层不动点映射算法:在内层,分别建立微网和配电网的凸优化模型,采用交替方向乘子法对模型进行分布式求解,进而确定电网最优定价策略;在外层,建立灵活性资源用户响应模型,用户根据内层的定价策略调整原有需求量。引入不动点定理解释该博弈问题,并证明其均衡解的存在性、唯一性和收敛性。算例仿真结果验证了所提策略的适用性与有效性。Aiming at the multi-microgrid distribution system with flexible resource,a pricing strategy for multi-microgrid distribution system based on dynamic non-cooperative game is proposed,which guides the user side to adjust the electricity consumption mode for realizing the system economic operation.A bi-layer fixed point algorithm is proposed.In the inner layer,the convex optimization models of microgrid and distribution network are respectively built,and the alternating direction multiplier method is adopted to distributionally solve the model,further the optimal pricing strategy of power grid is determined.In the outer layer,the user response model of flexible resource is built,and the users adjust the original demand according to the pricing strategy of inner layer.The fixed point theorem is introduced to explain the game problem,and prove the existence,uniqueness and convergence of its equilibrium solution.The example simulative results verify the applicability and effectiveness of the proposed strategy.
