考虑需求响应的互联交直流混合微电网的分布式经济调度模型

交直流混合微网能够高效集成分布式电源和柔性负荷，开放共享的互联系统能够通过功率共享机制进一步提高多微网的可靠性和经济性。提出了考虑需求响应的互联交直流混合微电网的分布式经济调度模型。对于单个微网，建立了考虑需求响应的优化模型来降低自身的运营成本，并通过添加备用容量约束来应对微网中的不确定性。对于整个互联系统，直流网络通过协调各微网的边界信息来优化潮流分布，降低网损。整个优化问题以分布式的方式进行求解，微网内部的负荷资源被充分协调，各微网仅需提供有限的边界信息，用户隐私被充分保护。算例结果证明了所提调度模型的有效性。

A Distributed Economic Dispatch Model for Networked Hybrid AC/DC Microgrids Considering Demand Response

Hybrid AC/DC microgrids can efficiently integrate distributed generations and loads, and the open and shared interconnected system can further improve the reliability and economy of multiple microgrids. In order to meet the requirements of easy expansion and privacy protection of interconnected systems, this paper proposes a distributed economic dispatch model based on the interconnected systems and the alternating direction multiplier method. For a single microgrid, the coordinated charging strategy of electric vehicles is used to avoid load peak out of limit, and the optimization model with demand response is used to reduce the operating costs. For the interconnected system, the DC network optimizes power flow to reduce network losses by coordinating the boundary information of each microgrid. The whole optimization problem is solved in a distributed manner, and each microgrid only provides limited boundary information, which fully protects the user privacy. The generation resources and load resources are also fully coordinated. The simulation results show the effectiveness of the proposed dispatch model.
