Quantitative evaluation of power supply reliability improvement in distribution network by customer-side integrated energy system

Abstract

In order to solve the problem of quantifying the construction benefit of distribution system with integrated energy system, a quantitative evaluation method is proposed, taking into account the impact of demand response. Firstly, the power supply model is established to determine power supply region of integrated energy system after distribution network failure. Then, the demand response model integrating time-of-use price and incentive is used to show the load changes before and after the implementation of demand response. Furthermore, the improvement effect analysis method of distribution network reliability by integrated energy system are proposed based on the sequential Monte Carlo method. In addition, the influence of various factors on the reliability is also studied. At last, take the improved RBTS 6 bus F4 as an example. Case study results show that the integrated energy system and demand response can improve the reliability of the distribution network.
