摘　　要：大规模风电并网后,由于系统在负荷低谷期的调峰能力不足,导致风电送出受阻现象凸显;与此同时,部分风电场附近建有大容量、调节能力强的高载能负荷,如何充分利用两者位置毗邻、需求互补的特点,通过高载能负荷就地消纳受阻风电的方式来提高风电的消纳能力,成为亟需研究的问题。文章首先分析高载能负荷消纳受阻风电的需求及技术潜力;其次以双边收益均衡且最大化为目标,将风电受阻电量作为交易商品,采用协商式双边直购的交易方式构建双边收益模型;最后在技术约束下遵循经济规律,提出基于纳什均衡的高载能负荷就地消纳受阻风电双边博弈决策模型,制定双边收益均衡且最大时的消纳电量及电价,并采用迭代搜索法求解该模型。算例验证了双边博弈决策的可行性和有效性。With the integration of large-scale wind power, the lack of peaking-shaving capability during light load period, led to severe congestion of wind power. At the same time, high-energy loads with large capacity and strong ability of regulation were built near some wind farms, so how to make full use of characteristics of their adjacent location and demand complementary, and to improve consumptive ability of wind power by the way of using high-energy load to consume congested wind power, became a problem in urgent need of research. Firstly, this paper analyzed the demand and the technical potential of consuming congested wind power by high-energy loads.Secondly, taking the electric quantity of congested wind power as a commodity and adopting the consultative bilateral direct purchase transaction mode, a bilateral income model was built. Finally,following the economic law and the technical constraints, a bilateral game decision-making model of using the high-energy load to consume congested wind power based on the Nash equilibrium was built. Then the consuming electric quantity and electricity prices with a balanced and maximum bilateral benefits were formulated. Besides, this paper used iterative search method to solve the model. Feasibility and effectiveness of the proposed strategy are demonstrated by simulation results.
