摘要
当风电场、光伏电站、电氢混合储能系统分属不同的投资者时,微网容量配置存在微网整体运行最优与各投资者自身运行最优的矛盾,同时风、光出力的不确定性也会影响容量配置。针对上述问题,提出一种考虑风、光不确定性,基于合作博弈的风-光-电氢微网容量配置方法。首先,依据有序聚类和K-均值聚类提取出风-光-负荷典型月场景;其次综合考虑影响微网运行的因素,构建基于不同投资者的经济模型,在典型月场景下,分析完全合作博弈、部分合作博弈、非合作博弈模式下各投资者与联盟的收益关系;最后,以月净收益最高为优化目标,利用改进灰狼优化算法配置投资者装机容量,并基于shapley值分配合作联盟投资者收益。根据算例结果和关键参数灵敏度分析可知,微网在完全合作博弈模式下兼顾经济性与低碳性,且各投资者利益分配合理;电价、风光补贴价格的波动对各投资者影响不同。
When wind farm,photovoltaic power station and hybrid electric-hydrogen energy storage system belong to different investors,there is a contradiction between the optimal operation of the microgrid as a whole and the optimal operation of each investor.Meanwhile,the uncertainty of wind and photovoltaic output also affects the capacity configuration.To solve the above problems,a capacity configuration method of wind-photovoltaic-electric hydrogen microgrid based on cooperative game is proposed,considering the uncertainty of wind and photovoltaic.Firstly,the typical monthly scenes of wind-photovoltaic-load are extracted based on ordered clustering and K-means clustering algorithm.Secondly,the factors affecting the operation of the microgrid are comprehensively considered,and an economic model based on different investors is constructed.Under the scenario of a typical month,the revenue relationship between each investor and the alliance is analyzed under the mode of full cooperation game,partial cooperation game and non-cooperation game.Finally,the highest month income is used as the optimization objective,the improved grey wolf optimization algorithm is used to allocate the installed capacity of investors,and the investor income of the cooperative alliance is allocated based on shapley value.According to the results of the example and the sensitivity analysis of key parameters,it can be seen that in the full cooperative game mode,economy and low carbon are taken into account,and the interests of each investor are distributed reasonably.The fluctuations of electricity price and wind-photovoltaic subsidy price have different effects on each investor.
