Influence of Incentive-Based Demand-Side Response on Distribution Network Reliability Considering Prosumers

With the increasing proportion of prosumers, user participation in demand-side response is no longer limited to the unidirectional power purchase mode, and the power delivered by prosumers to the distribution system is intermittent, which brings new challenges to the reliability and evaluation of the distribution network. In response, an incentive-based demand-side response (IBDR) including prosumers reliability evaluation method is proposed for distribution network in this paper. First, a bi-level optimization model is developed to represent the maximum user benefit, accounting for the coexistence of common users and prosumers, and the influence of this model on reliability evaluation is analyzed. Then, two indices, the satisfaction with demand-side response(SDSR) and the prosumer relative volatility(PRV), are introduced, which captures the reliability in evaluation. Finally, the reliability of the IEEE RBTS Bus6 model is evaluated using SDSR and PRV based on the Markov chain Monte Carlo. The results of the case study show that prosumers maximize the reliability benefits in summer, but also pose the highest risk of potential volatility.
