摘 要：針對(duì)微電網(wǎng)風(fēng)險(xiǎn)評(píng)估，建立了微電網(wǎng)風(fēng)險(xiǎn)指標(biāo)體系，該體系包括結(jié)構(gòu)安全、運(yùn)行安全和技術(shù)安全等各方面的一級(jí)指標(biāo)及相應(yīng)的子指標(biāo)。將層次分析法與模糊評(píng)價(jià)法進(jìn)行綜合，獲得了各層指標(biāo)的權(quán)重和綜合風(fēng)險(xiǎn)評(píng)估矩陣。結(jié)合實(shí)例對(duì)微電網(wǎng)總體風(fēng)險(xiǎn)情況進(jìn)行評(píng)估，分析結(jié)果直觀顯示了微電網(wǎng)中三大主要風(fēng)險(xiǎn)的重要性程度，且得到了其相應(yīng)子指標(biāo)的重要程度排序。

Abstract: In allusion to the risk assessment of microgrid, a comprehensive risk assessment index system for microgrid was built. The system included first-level indexes such as structure safety, operation safety and technique safety etc, and the corresponding sub-indexes. The paper integrated the analytic hierarchy process (AHP) method with the fuzzy evaluation method to obtain the weight of each layer index and the comprehensive risk assessment matrix. The whole risk situation of microgrid was evaluated via practical examples. The analysis results directly show that the three major risks in microgrid are very important, and each index has the sequence of their own degree of importance.
Key words: microgrid; risk assessment; analytic hierarchy process (AHP); fuzzy comprehensive evaluation method
