大规模风电并网对电网的影响及抑制措施研究

分析了风能发电的特点,指出大规模的风电并网将增加系统调峰困难,影响系统频率和省际联络线调节的稳定性,导致潮流断面重载增加并降低系统稳定性,增加系统无功调节难度,降低电网抵御故障的能力。针对辽宁电网风电接入的实际情况,提出了强化风电并网的调度及技术要求。同时,提出提高风电场发电稳定性最好的方法是在风电场建立储能系统。

Impact of Large-scale Wind Power Integration on Power System and Suppression Measures

Characteristics of wind power is analyzed,as it shows large-scale wind power integration increases the difficulty of peak regulation,affects the system frequency and the stability of interprovincial connection line.Also it increases the load of power flow interface,decreasing system stability and increasing reactive regulating difficulty and reducing grid capability to resist breakdowns.The scheduling of wind power integration and technical requirement is proposed in consideration of Liaoning status quo.At ...
