基于复杂网络理论的主动配电网多级运行风险快速评估
Rapid Assessment of Multistage Operation Risk of Active Distribution Network Based on Complex Network Theory
摘要
Abstract
The time‐varying topological structure , device and state diversity and random fuzziness and the self ‐healing ability of the active distribution network have brought new operational risks and challenges to the safety of the power grid . As methods of traditional analysis of the power system can hardly satisfy the demand of active distribution network , a new method is badly needed for assessment of active distribution network s operational risks and providing operational advice for automation system and dispatchers . Based on the complex network theory and the features of active distribution network , a rapid and multi ‐level operational risk assessment system capable for real‐time risk warning and multistage risk analysis is proposed , which allows for sufficient time to make appropriate operational decisions and real‐time protection of the power grid . On the premise of the active distribution automation system and some advanced mathematical tools such as the credibility theory , the system proposed can rapidly respond to the change of network structure and components , including the controllable loads , electric cars , distributed generators and energy storage devices . Qualitative and quantitative multistage operation risk assessment results are given to assist dispatchers to reduce the risks of system and prevent large area blackout . Finally , an example is given to illustrate the feasibility , rapidity , flexibility , practicality and applicability of the operational risk assessment system .关键词
