增量市场环境下多供电主体市场博弈模型与交易行为分析

研究新增供电主体参与电力市场的运营机制对电力市场的健康和可持续发展具有重要意义。构建包含配电网运营商、分布式电源运营商、储能运营商和用户的增量市场模型,分析各主体间的市场关系和价格传导机制;基于市场博弈理论,利用纳什均衡解的存在性条件构建增量市场环境下多主体参与的双层优化模型。仿真结果验证了所提模型及求解方法的有效性,增量市场环境下运营商供给能力是影响其博弈策略的关键因素,外部监管手段有利于培植新的供电主体,但也存在由于运营商规模不对等造成垄断电价的交易问题。

Market game model and trading behavior analysis of multiple power supply agents in increment electricity market

It is of great significance for the healthy and sustainable development of electricity market to research the operation mechanism of new added power supply agents participating in the electricity market. An incremental market model including distribution network agent, distributed generation agent, energy storage agent and users is built, and the market relationship and price conduction mechanism among each agent are analyzed. Based on the market game theory and existence condition of Nash equilibrium solution, a bi-level optimization model of incremental market participating with multiple agents is constructed. Simulative results verify the effectiveness of the proposed model and solving method, the supply capacity of agents is the key factor influencing their game strategies in the incremental market environment, and external regulatory measures are conducive to the cultivation of new power supply agents, but the trading problem of monopoly price caused by the unequal scale of agents is also exists.
