为应对风电渗透率的提高对电网调频所带来的挑战，从风电场站配储能系统的储能成本、实时电量收益、一次调频收益等方面，建立以储能系统容量和储能系统功率为决策变量的风电场站配储能系统参与一次调频服务全寿命周期成本-收益计算模型。针对一次调频动作量难以精准评估的难点，采用电力系统频率闭环动态过程开环处理方法建立了考虑风电机组控制和储能系统荷电状态（state-of-charge，SOC）约束的风储联合系统调频模型，提出以全年频率曲线为输入的风储联合系统一次调频动作量开环计算方法。通过结合风储联合系统调频仿真模型与风电场全年运行频率和功率数据进行仿真分析，获得了储能系统年储能成本和年一次调频收益的变化规律。结果表明，装机容量为30 600 kW的风电场，当储能功率为4 553.6 kW、储能容量为9 822.6 kWh时风储联合一次调频收益达到最优。

To address the challenges posed by the increasing penetration of wind power on grid frequency regulation, this paper establishes a life-cycle cost-benefit calculation model for wind farms equipped with energy storage systems participating in primary frequency regulation services. The model considers energy storage costs, real-time electricity revenue, and primary frequency regulation revenue, with energy storage capacity and power as decision variables. To tackle the difficulty of accurately evaluating primary frequency regulation actions, a frequency regulation model for the combined wind-storage system is developed using an open-loop processing method based on the closed-loop dynamic process of the power system frequency. This model incorporates wind turbine control and energy storage system state-of-charge (SOC) constraints, and proposes an open-loop calculation method for primary frequency regulation actions using annual frequency curves as inputs. By combining the wind-storage system frequency regulation simulation model with annual operational frequency and power data of the wind farm, the change rule of the annual energy storage costs and primary frequency regulation revenue are obtained. The results show that for a wind farm with an installed capacity of 30 600 kW, the optimal primary frequency regulation revenue is achieved when the energy storage power is 4 553.6 kW and the energy storage capacity is 9 822.6 kWh.
