基于风蓄协调的节能调度方法

为解决节能调度中风能接入造成运行成本增加和可靠性降低的问题，提出了一种基于风蓄协调系统的节能调度方法。通过引入多个整型优化变量与协调周期不平衡量约束，反映抽水蓄能机组发电、抽水、空闲等不同运行状态以及风电机组的出力波动特性，并采用混合整数规划方法求解。算例分析表明，该模型能克服风能的间歇性和波动性缺点，提高系统运行可靠性与风能利用率，降低整体运行成本，能提供抽水蓄能机组适应节能调度需求的新型调度方案，具有显著的经济效益与实用价值。

The energy-saving dispatch based on the coordination between pumped storage hydro and wind energy

To solve the problems of operation cost increase and reliability decrease after wind power integration in energy-saving dispatch,this paper proposes an energy saving dispatch method based on coordination between pumped storage hydro and wind energy. Through introducing several integer variables which denote different operation states (generation,pumping and idle) of pumped storage hydro unit,and the imbalance constraint during coordination period which illustrates the volatility characteristic of wind power...
