非合作博弈模式下新能源微电网多主体成本策略优化模型

Multi-agent cost optimization strategy model of new energy micro-grid based on non-cooperative game theory

根据微电网具有的特点,发电厂商提供可持续稳定的电能,尽可能就近输送,降低网损,提高有功转化,保持电价上的竞争优势以及增加新能源消纳。基于此,分析了参与新能源微电网的各主体之间的利益关系,即微电网发电侧、用户侧和配电网,构建了非合作博弈模式下的成本策略博弈模型,选取某微电网示范地区进行算例分析,结果表明,非合作博弈下的均衡策略可以满足微电网、配电网和用户侧三方收益最大化的需求,同时能够增加新能源消纳减少弃风弃光现象。

According to the characteristics of the micro-grid,power generation suppliers can provide sustainable and stable electric energy,and transport it as close as possible to reduce network loss and improve active power conversion,thus maintaining competitive advantage in electricity price and increasing new energy consumption.On this basis,the interest relationship among the main bodies participating in the new energy micro-grid is analyzed at first.Therefore,the cost strategy game model under the non-cooperative gaming mode between the generation side,the user side and the distribution network is constructed.A micro-grid demonstration area is selected for example analysis.The results show that the equilibrium strategy under the non-cooperative game can meet the demand of maximizing the revenue of three parties,namely,the micro-grid,the distribution network and the user side.Meanwhile,the consumption of new energy also increases and the wind and PV curtailment is improved.
