| 摘要: |
| 为了使储能系统在抑制风电功率波动的同时能够响应电网频率的变化，提出一种基于飞轮储能（FESS）的风电功率综合调控策略。在分析同步发电机电网频率响应过程的基础上，设计了飞轮储能的功率控制器结构，并对其参数进行配置。在MATLAB／ Simulink环境下进行了数字仿真研究，结果表明，所提出的控制策略能够使风电出力具有类似于同步发电机的惯量响应特性，同时使飞轮储能可以在功率控制和频率控制2种工作模式下灵活切换，从而有效改善风电功率的并网特性。 |

| Abstract: |
| A comprehensive control strategy based on FESS（Flywheel Energy Storage System） is presented to respond to the grid frequency variation while smooth the wind power fluctuation. The response process of synchronous generator to the grid frequency variation is analyzed，the structure of FESS power controller is designed and its parameters are configured. The results of digital simulation with MATLAB／Simulink show that，the proposed control strategy makes the wind power output possessing the inertia response character as the synchronous generator and allows the operating mode of FESS to be flexibly switched over between power control and frequency control，which improves the grid-connection performance of wind power. |
