针对光伏电站的出力波动性大和梯级水电站来水区间形势多变的问题,为应对光伏不确定性,考虑来水不确定性下光伏机组和水电机组的协调关系,提出一种考虑来水不确定性的梯级水电站优化调度模型。首先,通过分析梯级水电站的历史实测区间来水情况和光伏电站的太阳辐照度,基于改进K-均值聚类算法,建立区间来水和光伏不确定性典型场景;然后,考虑发电收益和弃电惩罚成本,以梯级水电站的总运行收益最大为目标,提出考虑来水不确定性的梯级水电站优化调度模型;最后,通过算例仿真验证该文提出的梯级水电站优化调度模型能够充分协调可调度资源,减少弃水弃光率,提升梯级水电站整体的运行经济性。
Abstract
Aiming at the problem of output fluctuation of PV power station and the changeable situation of inflow interval of cascade hydropower stations, in order to cope with the uncertainty of photovoltaic power, this study considers the coordination relationship between PV units and hydropower units under the uncertainty of incoming water, and proposes an optimal scheduling model of cascade hydropower stations considering uncertainty of incoming water. Firstly, by analyzing the historical measured interval incoming water of cascade hydropower stations and the solar irradiance of PV power stations, based on the improved K-means clustering method, the typical scenarios of incoming water and PV uncertainty are established. Then, considering the power generation income and the penalty cost of power abandonment, the optimal scheduling model of cascade hydropower stations considering uncertainty of incoming water is proposed with the goal of maximizing the total operating income of cascade hydropower stations. Finally, the simulation results show that the optimal scheduling model of cascade hydropower stations proposed in this study can fully coordinate the schedulable resources, reduce the rate of water and light abandonment, and improve the overall operation economy of cascade hydropower stations.
