考虑需求响应的产消群边缘自平衡交易机制研究

Research on Edge Self-balancing Trading Mechanism of Production and Sales Group Considering Demand Response

随着分布式光伏的大量普及,分布式光伏的就地消纳成为了亟需解决的问题。针对产消者具有负荷与电源双重属性的特点,提出了考虑需求响应的产消群边缘自平衡交易机制,首先通过产消群的边缘出清,实现产消群内部的电量交互,进而通过价格型需求响应的手段,进一步挖掘用户负荷的调节潜力,通过基于粒子群的购售电价格优化决策,在每一时段制定最优的产消群内部购售电价格,实现产消群的效益最优。仿真实验表明,所提交易机制及价格型需求响应优化策略,能够大幅降低产消群的用电成本,同时促进产消群内部自平衡。

With the proliferation of distributed photovoltaics,its local consumption has become an urgent issue.Considering the prosumer′s dual attributes of charge and power supply,this paper proposes a self-balancing edge trading mechanism based on demand response.Firstly,through the edge transaction of the prosumer group,the power interaction within the prosumer group is realized.Then,the price-based demand response means is used to further tap the adjustment potential of the user load.Through the optimization of purchase and sale price based on the particle swarm,the optimal purchase price of electricity within the prosumer group is established at each time period to achieve optimal benefit.Simulation experiments show that the proposed transaction mechanism and the price-based demand response optimization strategy significantly reduce the cost of electricity for the prosumer group and promote the internal self-balancing of the prosumer group.
