Abstract: With the increasing proportion of prosumers, the participation of users in the demand-side response is no longer limited to the unidirectional power purchase mode, and the power delivered by prosumers to the distribution network is intermittent, which brings new challenges to the reliability and evaluation of the distribution network. Based on this, this paper proposes an Incentive-Based Demand-Side Response including Prosumers (IBDR-P) reliability evaluation method for distribution network. Firstly, the user maximum benefit model with common user and prosumer co-exists is constructed by bilevel optimization, and the influence of this model on reliability evaluation is analyzed. Then the index Satisfaction with Demand-Side Response (SDSR) and the reliability evaluation index Prosumer Relative Volatility (PRV) taking into account the relative volatility of prosumers are introduced. Finally, the reliability of IEEE RBTS-Bus6 model is evaluated by using ISDSR and IPRV based on Markov chain Monte Carlo. The results of the example show that the prosumer can play the largest utility in improving reliability in summer, but at the same time there is the most prominent potential volatility risk.
