③ 摘要
在電力系統(tǒng)運(yùn)行中，維護(hù)潮流解是很重要的。在最近的管制環(huán)境中，因?yàn)椴煌碾娏灰缀鸵岳鏋榛A(chǔ)的業(yè)務(wù)計(jì)劃，不確定性已經(jīng)在電力系統(tǒng)中成為了比較普遍的現(xiàn)象。因此，在當(dāng)前和未來(lái)的電力行業(yè)，可能會(huì)有比在過(guò)去更多的無(wú)法解決的情況。本文提出了一種方法，以確定適當(dāng)?shù)臒o(wú)功功率賠償來(lái)恢復(fù)在無(wú)法解決的嚴(yán)重意外中的潮流解。為了分析潮流解，我們提出了一個(gè)用來(lái)確定支流參數(shù)的連續(xù)潮流工具。在可解的情況下，注入無(wú)功功率的適當(dāng)?shù)牡攸c(diǎn)由靈敏度分析而決定，這種靈敏度分析以結(jié)點(diǎn)上正常載體的獨(dú)立參數(shù)比較所得的由連續(xù)潮流工具建造的V曲線為基礎(chǔ)。那個(gè)靈敏性資料的效力，由比較無(wú)功補(bǔ)償在每個(gè)位置的數(shù)額來(lái)驗(yàn)證。在一個(gè)案例研究中，提出的這種算法是適用于韓國(guó)電力公社（電力）系統(tǒng)的。

In power system operation, maintaining power flow solvability is important. In the recent deregulated environment, uncertainty has become more prevalent in power systems because of diverse power transactions and benefit-based operational schemes. Thus, in the present and future power industry, there may be more unsolvable cases than there were in the past integrated power industry. This paper presents a methodology to determine the adequate reactive power compensation for restoring power flow solvability in the unsolvable severe contingencies. To analyze power flow solvability, a continuation power flow tool parameterizing branch parameters of contingencies is applied. In solvable cases, the adequate locations of the additional reactive power injection are determined by sensitivity analysis based on the normal vector at the nose point of the independent parameter vs. V curves, constructed by the continuation power flow tool. The effectiveness of the sensitivity information is verified by comparing the amount of reactive power compensation at each location. In a case study, the proposed algorithm is applied to the Korea Electric Power Corporation (KEPCO) Systems.
