摘要
压缩空气储能(CAES)系统包含用电储能和发电释能两个阶段。通过对CAES系统在发电释能和用电储能阶段参与一次调频的动作原理进行研究,首次提出CAES系统双向参与响应电网一次调频的方法:构建发电侧参与电网一次调频的功能模块,参考现有机组要求设置相应参数,设计了整套调节控制过程;通过选取可以调节负荷的压缩机、电动机在用电侧参与电网一次调频,并构建相应的功能模块;参考现有相关规程、要求,结合CAES系统特点,设置相应参数,设计整套调节流程。CAES系统双向参与电网一次调频将有效提高电网频率的调节能力,缓解了新能源大规模并网后带来的频率波动问题,具有广阔的应用前景。
Compressed air energy storage(CAES) system includes two processes of power consumption energy storageand power generation energy release.Based on the study of the action principle of CAES system participating in primary frequency regulation in the stages of power consumption energy storage and power generation energy release, a method of CAES system bidirectionally participating in primary frequency regulation of power grid is proposed.In the generation side, a complete set of regulation and control process that CAES system participates in the primary frequency regulation is designed on the basis of constructing the corresponding functional module and setting the corresponding parameters with reference to the existing unit requirements.In the power demand side, CAES system participates in the primary frequency regulation by selecting compressors which can adjust the load, and the corresponding functional modules are constructed.The corresponding parameters are set and the whole regulation process is designed in accordance with the existing relevant regulations and requirements and the characteristics of CAES system.CAES system bidirectionally participating in primary frequency regulation of power grid will effectively improve the frequency regulation ability of power grids, and alleviate the frequency fluctuation problem caused by large-scale grid-connection of new energy, and have broad prospects in application.
