Reliability Evaluation of Distribution System with Multi-energy Integration Considering Comprehensive Demand Response

Aiming at the coupling characteristics of integrated energy system, this paper studies the reliability of integrated energy system considering demand response. Firstly, the quantitative index and calculation method of distribution system reliability evaluation are studied, and the structure and model of integrated energy system are established. Secondly, integrated demand response models based on electricity price and incentive are established respectively to get the optimization of demand response afterload curve. The effect of demand response on distribution system reliability is analyzed theoretically. Finally, the Monte Carlo simulation of general distribution system is extended to the integrated energy coupled distribution system, and the combination of demand response load curve and timing Momte Carlo simulation process is considered. Based on MATLAB, Momte Carlo simulation is used to calculate the reliability index of distribution system. The comparison of reliability indexes under different scenarios and different types of demand response implementation is realized by concrete examples, which verifies the effectiveness of the model and algorithm in this paper.
