摘　　要：在含高比例风电的新型电力系统中,针对由于缺乏灵活性调节激励机制造成的灵活性资源调节积极性不高、风电波动性平衡困难的问题,该文提出一种考虑灵活性补偿的高比例风电与多元灵活性资源博弈优化调度方法。首先,计及风电波动性与负荷波动性的时空耦合特性,定义了风电波动性评价指标,并以此为基础提出了风电灵活性调节需求量化方法;然后,考虑各灵活性资源主体决策的差异性和趋利性,提出了基于主从博弈的灵活性供需均衡分析方法,以各主体利益最大化为目标建立灵活性资源供需博弈优化模型;最后,通过仿真案例验证了所提方法可以有效提高源-荷-储多方灵活性资源参与调节的积极性,并促进高比例风电的上网消纳。The large scale grid connection of new energy sources,mainly wind power,has led to increasing uncertainty and anti-peak characteristics of the system,and the system is facing a huge challenge in terms of power balance.At present,scholars have explored the flexibility regulation potential of the system from multiple levels of"source-load-storage",which has improved the flexibility of system operation to a certain extent,but there are problems such as the lack of incentive mechanisms for flexibility regulation,the lack of reasonable compensation for the flexibility value of flexibility resources,and the lack of enthusiasm of flexibility resources to participate in regulation.This paper proposed an optimal dispatching method taking into account the game between a high proportion of wind power and multiple flexibility resources.On the basis of the individual profit-seeking properties of wind power and each flexibility resource subject,it used the idea of Stackelberg game to establish a multi-object game optimal dispatching model for supply and demand of flexibility regulation services,so as to achieve the optimization of supply and demand of flexibility resources and reasonable compensation of flexibility value.Firstly,considering the spatial and temporal coupling characteristics of wind power volatility and load volatility,the evaluation index of wind power volatility was defined,and based on this,a method for quantifying the demand for wind power flexibility regulation was proposed.Secondly,considering the differences and tendency of each flexibility resource’s decisions,a method of equilibrium analysis of flexibility supply and demand based on Stackelberg game was proposed,and an optimization model of flexibility resource supply and demand game was established with the objective of maximizing the interests of each subject.Finally,the proposed method was verified through simulation cases that the proposed method can effectively improve the enthusiasm of multiple flexibility resources to participate in regulation
