【摘要】：分布式电源和负载可在配电侧形成电能供给和消费的联盟,并参与区域电力市场交易。相比于单独进行交易,这样的联盟通过帮助市场能力较弱的分布式电源和负载参与到配电网市场中,推动配电网中的中小型负载和分布式电源之间的直购电业务的发展,促进配电网侧的电力市场形成;同时利用市场信号引导分布式电源和负载的电能生产和消费过程,使得它们获得更多的经济利益,促进分布式可再生能源的发展。文中给出了区域配电网中联盟交易模式的存在条件,并且基于公用电网的作用和合作博弈理论,建立了相应的交易价格模型。进一步,以集成售电商的收益为优化目标,构建了联盟选择和定价的优化决策模型。仿真算例说明了联盟交易模式的理论可行性,证明了在不同运行场景中所提优化决策模型的有效性。
[Abstract]:Distributed power generation and load can form a power supply and consumption alliance at the distribution side and participate in regional electricity market transactions. Rather than trading alone, such alliances promote the direct purchase of electricity between small and medium-sized loads and distributed sources in the distribution network by helping weak distributed power sources and loads to participate in the distribution network market. At the same time, market signals are used to guide the production and consumption of distributed generation and load, so that they can gain more economic benefits and promote the development of distributed renewable energy. In this paper, the existence conditions of alliance transaction model in regional distribution network are given, and the corresponding transaction price model is established based on the function of public power network and cooperative game theory. Furthermore, the optimization decision model of alliance selection and pricing is constructed with the revenue of integrated vendors as the optimization goal. A simulation example shows the theoretical feasibility of the alliance trading model and proves the effectiveness of the optimal decision model proposed in different operation scenarios.
