摘要
针对大规模风电并网对电网带来的网损增加问题,本文以大规模风电基地建有高载能负荷为研究背景,对高载能负荷跟踪风电波动进行调节对电网降损的影响机理进行了深入研究。在此基础上,对高载能负荷调节特性进行了分析,提出了高载能负荷跟踪风电波动进行调节的降损控制策略。最后,以大规模风电接入的甘肃河西电网为例,仿真验证了策略的有效性。
In light of the problem of network loss increase brought by large-scale wind power integration, this paper is based on the large-scale wind power base with high-energy loads, and conducts further research on influence mechanisms of high-energy loads involved in adjustment section by tracking wind power fluctuations on network power loss. Based on these, we analyze the regulation characteristics of high-energy load, and propose network loss reduction control strategies with high-energy load involved in the adjustment section by tracking wind power fluctuations. Finally, with Hexi grid containing large-scale wind power as the background, we verify the effectiveness of the strategies by simulation.
