摘要

由于风电功率存在间歇性、波动性，大规模风电并网给电网安全稳定运行带来了挑战。为此，提出了基于双馈变速抽蓄机组的风电功率波动平抑控制策略。首先，基于DIgSILENT/PowerFactory软件，建立了双馈变速抽蓄机组发电、抽水状态下的仿真模型，验证其快速功率控制能力。其次，基于低通滤波原理，结合风电预测功率，建立双馈变速抽蓄机组在发电、抽水2种工况下参与平抑风电功率波动的控制模型。最后，通过仿真算例进行验证，结果表明：双馈变速抽蓄机组具有快速功率响应特性；在发电和抽水2种工况下，均可有效平抑风电功率波动，减小常规机组调节压力，改善地区电网稳定性。

Abstract

Due to the intermittent and fluctuant of wind power

large-scale wind power grid-connected poses a challenge to the safe and stable operation of the power grid. Therefore

a wind power fluctuation suppression control strategy based on doubly-fed variable-speed pumped storage unit was proposed. Firstly

based on DIgSILENT/PowerFactory software

the simulation models of doubly-fed variable-speed pumped storage unit under the conditions of power generation and pumping were established to verify its fast power control capability. Secondly

based on the principle of low-pass filtering

combined with the wind power prediction

the control models of the doubly-fed variable-speed pumped storage unit were established to suppress wind power fluctuation under the conditions of power generation and pumping. Finally

a simulation example was given to verify the control strategy. The results show that the doubly-fed variable-speed pumped storage unit has fast power response characteristics. Under the conditions of power generation and pumping

the fluctuation of wind power can be effectively suppressed

the regulation pressure of conventional units can be reduced

and the stability of regional power grid can be improved.
