A Study on On-line Evaluation Method for User Side Power Supply Risks

Establishment of power supply risk evaluation indicator system is the key to realize power grid operational security evaluation. Based on distribution-purposed integrated model, this paper provides a method for evaluation of user side power supply risks under transmission-distribution coordinated continuous power supply. With this method, a power supply risk evaluation indicator system that considers both security and reliability for important users with continuous supply demand can be established and all-sided assessment on power supply security can be conducted, so it is easier for the controller to master the real-time continuous power supply state and communicate weak points of power supply security to important users. As a whole, this paper provides support for more efficient regulation and control.
