拟定了风电-抽水蓄能联合系统3种可行的运行方案:全部风电供给抽水蓄能电站抽水;根据电网容量和风电场出力情况,部分风电直接输入电网,其余风电供给抽水蓄能电站抽水;风电全部直接输入电网.建立了风电-抽水蓄能联合系统的优化运行模型,计算得出了常规发电厂稳定运行的最小容量以及含一定容量风电的电网所需的抽水蓄能电站装机容量,建立了经济评价模型。根据综合经济评价结果,优选出了风电-抽水蓄能联合系统的最佳运行方案.

能量枢纽(EH)可以促进不同形式的能源载体协同运行,是加快泛在电力物联网关键技术研究的重点。提出了一种基于非合作博弈的多EH优化运行方法,将包含多能源系统的单个园区抽象为一个EH,对EH中的能源生产、转换及储能设备进行建模,建立多能协同运行的EH框架;在此基础上,构建基于纳什均衡的多EH非合作博弈模型,各EH以日运行成本最小为目标函数与其他EH参与博弈,分析各EH中设备出力和负荷平衡情况。基于MATLAB进行仿真运行,结果表明多个EH之间能充分利用区域间负荷互补特性,使各EH在优化个体运行成本的同时,提高系统的灵活性。

Abstract—This paper proposes an adaptive optimal policy for hourly operation of an energy storage system (ESS) in a gridconnected wind power company. The purpose is to time shift wind energy to maximize the expected daily profit following uncertainties in wind generation and electricity price. A stochastic dynamic programming (SDP) framework is adopted to formulate this problem, and an objective function approximation method is applied to improve the SDP computational efficiency. Case studies on the Electric Reliability Council of Texas demonstrate that the resultant profits from SDP-based operation policy are considerably higher than those from deterministic policy, and comparable to those from the perfect information model. It is concluded that the presented SDP approach can provide operation policy highly adaptive to uncertainties arising from wind and price. The proposed framework can help the wind company optimally manage its generation with ESS.
