Abstract:
Given the current situation that there is no comprehensive and reasonable risk assessment index system for industrial users' safe electricity consumption in the process of multi-round control and restoration, a comprehensive risk assessment index system for industrial users' safe electricity consumption is constructed in this paper, and a strategy for multi-round load control and restoration that takes into account the comprehensive risks of industrial users' safe electricity consumption is proposed. Firstly, a comprehensive risk assessment index system consisting of 21 indicators is structured; secondly, the risk assessment method combining with the game assignment and the cloud modeling is used to obtain the risk levels of the industrial users. Then, a multi-round load control strategy based on the dynamic adjustment of regulation volume based on the controllable risk threshold, and a multi-round load recovery strategy based on the sequence set of the controlled amount of important loads and the risk severity of load equipment are put forward. Finally, the effectiveness of the proposed multi-round load control and recovery strategy is verified by using the IEEE-RTS-24 system as a practical scenario and a steel plant as an example. The proposed strategy ensures that the industrial users can participate in the multi-round control and recovery process with a low-risk level and also meets the requirements of the safe and reliable operation of the grid.
