摘要
风电出力的实际值与预期值的偏差较大会对电网的安全稳定运行带来冲击,从而制约风电大规模并网。为解决这一问题,文章提出在电力市场环境下通过风电-抽水蓄能联合运行的方式来弥补风电出力偏差。在研究独立运行模式的基础上建立联合运行模型,研究两种模式下抽水蓄能电站的经济效益以及联合运行模式的综合效益。算例分析验证了风电-抽水蓄能联合运行模式在技术上与经济上的可行性,联合运行模式虽然在一定程度上减少了抽水蓄能电站的电量收益,但实际综合效益比独立运行模式的经济效益有大幅度提高。
The participation of wind energy in electricity markets requires providing a forecast for fu-ture energy production of wind generators, greater deviation between prediction and real power outputcould impact stability of power grid and restrain wind power from grid integration. In order to solve theproblem, a joint operation between a wind farm and hydro-pump plant is proposed to compensate windpower prediction error. Furthermore, the economic benefit of hydro-pump plant is analyzed in the con-dition of both independent operation and joint operation. Although power generation income of hydro-pump plant will decrease under joint operation model, but the comprehensive economic effect rises ac-tually when the stable output of wind power is considered.
