摘　　要：风光新能源出力不确定性降低市场竞争,梯级水风光储互补参与电能-调频市场已成为实现高质量可再生能源供应的有效手段。为此,首先提出梯级水风光储系统参与电能-调频辅助服务市场的日前投标模型和实时调整及调频响应模型。其次,针对风光出力的不确定性,采用基于Wasserstein距离模糊集的分布鲁棒机会约束,构建梯级水风光储参与市场的分布鲁棒机会约束模型。最后,以日前市场收益最大和实时调整偏差最小进行双目标优化。采用规格化平面约束法求取帕累托前沿解,并采用逼近理想解排序法(TOPSIS)法筛选帕累托解集得到最优方案。以西南地区梯级水风光储系统为例展开算例分析,验证了模型的合理性和所提方法的有效性。Uncertainties in wind and solar power outputs reduce their market competitiveness.Participation of cascade hydropower,wind,solar,and storage systems in energy and frequency regulation markets has become an effective means to achieve high-quality renewable energy supply.This study first develops a day-ahead bidding model and a real-time adjustment and frequency regulation response model for such hybrid systems that participate in these regulation markets.To address the uncertainty in wind and solar outputs,we develop a distributionally robust chance-constrained model,based on the Wasserstein distance fuzzy set for the systems'market participation.Then,a bi-objective optimization is made to maximize day-ahead market revenue and minimize real-time adjustment deviations.And a normalized normal constraint(NNC)method is used to obtain Pareto frontier solutions;the Technique for Order Preference by Similarity to an Ideal Solution(TOPSIS)method is used to select the optimal solution from the Pareto front.Application to a case study of a river basin in southwestern China verifies our method and the models prove effective,rational,and applicable.
