摘要

为研究现货市场下“光热+”可再生能源的经济调度策略，以50 MW塔式光热电站与300 MW风电场组成的联合发电系统为研究对象，建立关键部件及子系统数学模型。基于分布鲁棒优化理论，综合1-范数和∞-范数构建不确定集，以系统收益最大为目标，建立计及风电不确定性的联合系统两阶段优化调度模型，获得联合发电系统参与电力现货市场的最优出力分配，并与独立系统参与现货市场的收益比较研究。结果表明，在联合发电系统同时参与能量市场和辅助服务市场的场景下，与独立系统相比，联合发电系统风电偏差惩罚降低92.70%，系统整体收益提高3.19%；最后分析获得风电历史数据量、概率分布置信度、最大调频容量及旋转备用容量对系统总收益的影响。

Abstract

In order to study the economic scheduling strategy for the renewable energy systems combined with the solar thermal power in the spot market， a mathematical model of the key components and subsystems is established. A combined power generation system composed of a 50 MW solar power tower plant and a 300 MW wind farm taken as the research object. Based on the theory of distributional robust optimization， the uncertainty set is constructed by integrating the 1-norms and ∞-norms. A two-stage optimal dispatch model for the combined system， considering wind power uncertainty， is established with the aim of maximizing system revenue. The optimal output allocation of the combined system to participate in the electricity spot market is obtained， and compared with the revenue of the independent system participating in the spot market. The results show that in the scenario， where the combined generation system participates in both the energy market and the auxiliary service market， the wind power deviation penalty of the combined system is reduced by 92.70% and the revenue is increased by 3.19% compared to the independent system. Finally， the impacts of the historical wind power data volume， confidence level， maximum frequency regulation capacity and rotating standby capacity on the overall system revenue are analyzed.
