This paper proposes a novel risk evaluation system for HVDC planned maintenance using probabilistic method. A quantitative evaluation method is put forward to measure how HVDC system maintenance affects power system reliability. Two major indexes, which are loss of load probability (LOLP) and Security Index (SI), are chosen to construct the power grid operation risk indexes. Based on the calculation...
Noticing the ever increasing dependency of life to the electrical energy, continuance of high quality service non-failure of power is very important for consumers. For achieving this goal, each main part of power system should have proper reliability. Some Papers have introduced the modeling methods for reliability evaluation of Transferring and Distribution parts at the power systems, But this paper...
In order to prepare for the intelligent management of power companies, it is significant to research on reliability evaluation method of power communication network. In this paper, 19 power corporations are chosen to be evaluated. The FAHP and entropy method are combined to make out the indicator weight. The restricted coefficient method is used to de-fuzzy the evaluation results. Then it improves...
