摘要

Integrated energy system (IES) is an important part of energy Internet, and its reliability evaluation is of great significance to the safe operation of the system. Therefore, a reliability evaluation method of IES considering integrated demand response (IDR) is proposed. Firstly, an optimization evaluation model considering IDR is established, which takes the minimum total operating cost as the objective function and power balance, equipment operation limitation and line capacity as restraint Condition. Secondly, the reliability evaluation index is proposed, and considering the dynamic characteristics and temporality of IES, the Markov Chain-Monte Carlo (MCMC) method suitable for the reliability evaluation of IES is proposed. Finally, the reliability of IES in different cases is evaluated by example simulation, and the simulation results verify the effectiveness and correctness of the proposed method.
