|
摘要
本文提出了一种计及多种因素间协调的梯级水电站群调度策略,以兼顾梯级水电站群的经济效益和社会效益。首先引入发电弃水量、抗旱放水量、以及泄洪水量等参数,用以完善梯级水电站数学模型;提出采用虚拟水库来表征流域分布泄洪点及抗旱灌溉点,并建立相应的数学描述;考虑梯级水电站水力调度,火电站的发电机组出力、能耗成本及污染排放三者之间,梯级电站的出力、发电流量、发电弃水量、防洪水量、抗旱水量与其它水力耦合参数之间,以及水火电机组联合调度之间综合效益基础上,建立了多目标综合节能调度模型;算例验证了该算法的可行性,并具有较为明显的节能效果和社会效益。
Propose a scheduling strategy for cascade hydropower plants considering the coordination of a variety of factors. Improve the mathematical model of cascade hydropower stations with three kinds of spill factors. Introduce the concept of virtual power plant to represent the site of flood control spill,and its mathematic expression is put forward.Consider the comprehensive benefits of hydro and thermal power,including the coordination of water scheduling,units output and energy cost and pollution emission of thermal plants,the coordination of power outputs of hydro plants,water flow of electric generation,power generation spill,flood control spill,anti-drought spill and other water power parameters. Proposed an energy saving scheduling model with above multi-objects. Finally,the proposed method is simulated on a power system with several hydro power plants and thermal power plants,and its feasibility is verified on energy saving and social benefit.
