AbstractIn the context of electricity market, available transfer capability (ATC) is an important indicator of the further usable amount of transmission capacity for commercial trading. It is very meaningful and useful to quickly estimate the effect of any operation parameters perturbation on the ATC value, once a transfer capability value has been given. This paper presents a model for calculating the first order sensitivity of ATC with respect to the variation of any parameters. Combining with continuation power flow (CPF) method, the new ATC can be estimated very fast with first order accuracy. The perturbation parameters include the real injection of bus, regulated voltage of generator bus, and other simultaneous transfer. These sensitivity coefficients can be quickly calculated, and be verified with CPF method. Test results on IEEE 30 bus system shows the efficiency and rapidness of the proposed method. 在電力市場環境下 ,可用輸電能力 (ATC)是反映輸電設備可用于能量交易的剩余容量的重要指標。ATC一旦確定后 ,快速估計出系統參數變化對輸電能力的影響具有很大的實際應用價值。文中首先基于連續潮流方法 ,考慮輸電支路的過負荷約束、發電機有功及無功出力約束和節點電壓約束 ,計算出ATC的值 ;然后推導出ATC對多種運行參數攝動的一階靈敏度計算模型 ,運行參數包括節點負荷功率、發電節點端電壓以及給定的能量交易 ,這些靈敏度系數能夠很快地計算 ;最后 ,使用了IEEE 30節點系統的算例來驗證文中所提出的方法的有效性和快速性。
