摘　　要：相邻海上风电场间因尾流效应产生功率时移能力,可为海上风电场群参与电网有功优化调度提供有效支撑。提出一种考虑场间功率时移的海上风电场群联合储能优化调度方法。首先,基于海上风电场群功率预测与电网有功调度计划量化风电场群功率跟踪需求;计及风速传播时间建立场间功率时移模型,利用风电场间功率时移能力参与电网调度;针对出力偏差协调储能进一步跟踪调度计划。然后,以系统运行成本最小为目标,构建考虑场间功率时移的海上风电场群储能优化调度模型。最后,以某实际海上风电场群储能系统为例进行仿真验证,结果表明所提方法能够利用相邻海上风电场间功率时移能力,有效降低储能调用成本,实现海上风电场群对电网有功调度计划的跟踪。The power time-shift ability between adjacent offshore wind farms due to the wake effect can provide an effective support for offshore wind farm groups to participate in the active power optimization scheduling of the power grid.An optimal scheduling method of offshore wind farm groups with energy storage considering the time shift of inter-site power is proposed in this paper.Firstly,the power tracking requirements of a wind farm group are quantified based on the power forecasting of the offshore wind farm group and the active power scheduling plan of the power grid.Considering the wind speed propagation time,the power time-shift model between wind farms is established,and the power time-shift ability between the wind farms is used to participate in grid scheduling.Energy storage is coordinated to further track the scheduling plan for the output deviation.Then,in order to minimize the operation cost of the system,the optimal scheduling model of the joint energy storage of the offshore wind farm group considering the power time shift between the farms is constructed.Finally,an actual offshore wind farm group with the energy storage system is taken as an example for simulation verification.The results show that the proposed method is able to effectively reduce the energy storage scheduling cost,and achieve the tracking of offshore wind farms to the grid active power scheduling plan by using the ability of power time shift between the adjacent offshore wind farms.
