摘 要:風(fēng)電容量可信度是衡量風(fēng)力發(fā)電對電力系統(tǒng)可靠性貢獻的重要指標(biāo)。建立風(fēng)速、風(fēng)電機組和風(fēng)電場出力模型,并考慮尾流效應(yīng),將風(fēng)電場處理為等效的多狀態(tài)發(fā)電機組。基于發(fā)電系統(tǒng)可靠性指標(biāo)定義了風(fēng)電場的容量可信度,采用截弦法計算得到風(fēng)電場的容量可信度。以加入風(fēng)電場后的IEEE RTS-96系統(tǒng)作為算例進行評估,通過風(fēng)電滲透率、系統(tǒng)備用、常規(guī)機組強迫停運率等因素對風(fēng)電場容量可信度的影響分析,驗證了該方法的正確性和有效性。
關(guān)鍵詞:風(fēng)電場;容量可信度;多狀態(tài)機組;風(fēng)電滲透率

Abstract: Wind power capacity credibility is an important index to measure the contribution of wind power for power system reliability. This paper established the wind speed, wind turbines and wind farm output models, taking wake flow effect into consideration, to treat wind farm as the equivalent polymorphic generators. Based on power system reliability index, this paper defined capacity credibility of wind farm and adopted the secant method to calculate the wind farm capacity credibility. With IEEE RTS-96 system added after wind farm as algorithm examples to carry out evaluation, this paper analyzed the wind power penetration rate, system reserved capacity and forced outage rate of routine generators etc impacts on wind farm capacity credibility, which verified the correctness and validity of the method.
         Key words: wind farm; capacity credibility; polymorphic generators; wind power penetration rate
