摘要:多源分布式能源的使用增加了微网负荷频率控制的不确定性，影响其安全运行，为此，提出一种用于微网调频的风电和抽水蓄能综合控制方法。首先，为了在微网发生负荷扰动时提供足额的功率支撑，设计风机限转矩控制，以快速提取转子动能响应一次调频；然后，针对限转矩控制导致的频率二次跌落问题，抽水蓄能提供辅助支撑以减少该问题对频率稳定的不利影响；最后，考虑风机输出和负荷扰动的非相关性，以及风电输出调整范围过窄的约束，设计抽水蓄能二次调频控制方法，利用其抽水工况和发电工况的实时切换消除风速和负荷不匹配时的稳态频率偏差。在MATLAB/Simulink上对所提方法进行仿真验证，结果表明，在不同风速和负荷扰动情况下，风电与抽水蓄能综合控制方法能够实现调频的完备性，并降低弃风率。

Abstract:The use of multi-source and distributed energy increases the uncertainty of load frequency control in the microgrid and has a negative impact on its safe operation.For this，a comprehensive control method for wind power and pumped storage in the frequency regulation of microgrid was proposed in this paper.Firstly，in order to provide sufficient power support when load disturbance occurred in microgrid，the limited torque control method was applied to extract the rotor kinetic energy of wind turbine in the primary frequency regulation.Secondly，in order to solve the problem of secondary frequency drop caused by limit torque control，the pumped storage system was implemented to reduce the adverse effect on the frequency stability by the auxiliary support.On the basis of them，considering the inconsistency between the output of wind turbine and load disturbance，and the narrow restriction of the wind power output adjustment range，the pumped storage control strategy with the secondary frequency regulation was designed.The proposed method could remove the steady-state frequency deviation resulted by mismatch between the wind speed and load disturbance by timely switching pumping condition and power generation condition.Finally，the proposed method was simulated in MATLAB/Simulink，the results showed that the comprehensive control method of wind power and pumped storage could realize the completeness of frequency regulation and reduce the wind abandonment rate under different wind speed and load disturbance.
