Reliability and sensitivity analysis of loop-designed security and stability control system in interconnected power systems
摘要
Abstract
Security and stability control system (SSCS) in power systems involves collecting information and sending the decision from/to control stations at different layers; the tree structure of the SSCS requires more levels. Failure of a station or channel can cause all the execution stations (EXs) to be out of control. The randomness of the controllable capacity of the EXs increases the difficulty of the reliability evaluation of the SSCS. In this study, the loop designed SSCS and reliability analysis are examined for the interconnected systems. The uncertainty analysis of the controllable capacity based on the evidence theory for the SSCS is proposed. The bidirectional and loop channels are introduced to reduce the layers and stations of the existing SSCS with tree configuration. The reliability evaluation and sensitivity analysis are proposed to quantify the controllability and vulnerable components for the SSCS in different configurations. By aiming at the randomness of the controllable capacity of the EXs, the uncertainty analysis of the controllable capacity of the SSCS based on the evidence theory is proposed to quantify the probability of the SSCS for balancing the active power deficiency of the grid.关键词
