摘要
为研究风电并网环境下考虑抽水蓄能电站在内的机组组合问题及系统最优调度策略,从系统角度出发,以运行成本最小化建立目标函数,结合各类电源的技术特性和系统的运行实际建立约束条件,并利用混合整数算法对模型进行优化计算。通过10机组系统的算例分析,得出常规火电机组、风电以及抽水蓄能电站的最优调度策略。运行结果表明,抽水蓄能电站参与系统运行有提高风电并网水平、减少火电机组的燃料成本和启停成本、可使电网负荷曲线趋于平稳三方面的效益。
In order to study unit commitment and optimal scheduling, the optimization model is established by consid- ering the participation of pumped storage power station and wind power. The objective function is selected as the minimum operation cost. The technical characteristics of each power sources and actual operation of system are chosen as constraints. The mixed integer algorithm is used to solve the model. The optimized operation of thermal power unit, wind power and pumped storage power is obtained by a 10-units system. Example results show that pumped storage power station can greatly improve the level of wind power gird integration, reduce thermal unit cost, and make grid load curve steady.
