抽水蓄能电站黑启动最优预留水量

Black-start Optimal Reserved Water of the Pumped Storage Power Station

在以火力发电机组为主的电网中,为满足黑启动需要所预留水量的大小直接影响抽水蓄能电站的削峰填谷效益。为使抽水蓄能电站的综合效益最大,提出了抽水蓄能电站的黑启动效益及黑启动所需水量的计算方法。综合考虑抽水蓄能电站的黑启动效益和静态效益,结合削峰填谷的边际运行位置约束,建立了抽水蓄能电站最优预留水量计算模型。以山东电网为例说明了该模型和算法的合理性。

In a power grid mainly relying on the thermal generator set, the reserve water used to meet the needs of black start has a direct impact on the benefits of peak load shifting. In order to get the largest benefits of the pumped storage power station, the calculating method for black-start benefits and the required water of black-start are proposed. Considering the black-start benefits of the pumped storage power station, static benefits and the constraint of the marginal running position, the calculation model for optimal reserve water is developed. Simulation results of Shandong power grid in China show that the model and method proposed are effective.
