摘要

于微电网拓扑结构和运行状态，提出了微电网运行脆弱性评估方法。首先定义了孤岛运行状态下的微电网脆弱性；其次对微电网进行脆弱性实时评估，分析微电网脆弱性实时评估的各种影响因素，建立微电网脆弱性实时评估概率模型，并基于风险理论建立风险后果度量函数。最后，通过算例验证评估方法的有效性及合理性。可以及时找出微电网脆弱性环节，为实现自愈提供理论基础。

Abstract

A vulnerability assessment method for micro-grid operation is proposed in this paper based on micro-grid topological structure and operation state.Firstly

the concept of micro-grid vulnerability is defined under the isolated island operation state.Secondly

real-time probabilistic model is established for vulnerability assessment after analyzing influencing factors of vulnerability and risk consequence generous character function based on risk theory is established.Finally

the proposed model is verified on a typical case.The simulation results show that the weak part can be found timely

which provides the reference for self-healing decision.
