摘要

这项工作涉及可再生能源发电并网下的电网频率控制。抽水蓄能水电(PSH)被提出用于补偿可再生能源的可变发电。当可再生能源发电造成电力短缺(过剩)时,PSH处于发电(抽水)模式。为了保持频率控制能力,考虑了可再生能源发电的允许变化水平。该解决方法在泰国电力局(EGAT)普密蓬水电站PSH机组上进行了试验。研究发现,在抽运模式下,PSH对频率控制的作用比在发电模式下更为明显。

Frequency Control of Electricity Grid Integrated with Variable Generation Using Pumped Storage Hydro Power Plant
This work involves frequency control of electricity grid under the integration of renewable generation. Pumped storage hydro (PSH) is proposed to provide compensation for variable generation of renewable sources. PSH is in generating (pumping) mode when there is a power shortage (excess) caused by renewable generation. To maintain the ability of frequency control, the allowable variation level of renewable generation is considered. The solution method is tested with the PSH unit at Bhumibol dam, a hydro power plant of The Electricity Generating Authority of Thailand (EGAT). It is found that the role of PSH on frequency control in pumping mode is more obvious than in generating mode.
