摘　　要：新能源出力强不确定性给新型电力系统调峰带来极大挑战,而光热电站的可控调节能力可为新型电力系统提供灵活性调节资源平抑系统的功率不平衡。为应对新型电力系统灵活运行需求,挖掘光热电站灵活性支撑潜力,提出了一种光热电站参与能量-灵活性市场的出清策略。首先,构建光热电站的能量管理模型,分析其灵活调控能力,为参与市场环境下电网灵活调控提供模型基础;然后,计及碳排放交易成本,以运营成本最小为目标构建光热电站参与联合能量-灵活性市场出清模型,并通过交替方向乘子法进行求解;最后,通过吉林西部某实际电网算例对所提方法进行分析验证,结果表明所提方法可有效降低系统总运营成本的同时,光热电站收益增长了34.23%。The strong uncertainty of new energy output poses great challenges to the peak shaving of new power systems,and the controllable regulation ability of concentrating solar power plants can provide flexibility to regulate resources and smooth out power imbalances in the new power system.In order to cope with the flexible operation requirements of new power systems and tap the flexibility support potential of solar thermal power stations,a clearing strategy for solar thermal power stations to participate in the energy-flexibility market is proposed.Firstly,an energy management model is constructed for concentrating solar power plants,their flexible regulation capabilities are analyzed,and a model foundation is provided for participating in flexible regulation of the power grid in a market environment.Then,taking into account the cost of carbon emissions trading,a concentrating solar power plant participation in the joint energy and flexibility market clearing model is constructed with the goal of minimizing operating costs,and solved using the alternating direction method of multipliers.Finally,the proposed method is analyzed and validated through an actual power grid example in western Jilin.The results show that the proposed method can effectively reduce the total operating cost of the system,while increasing the revenue of concentrating solar power plants by 34.23%.
