摘要： 随着用户中产消者占比上升，用户参与需求侧响应不再局限于单向购电模式，且产消者向配电网输送的电能具有间歇性等特点，对配电网可靠性及其评估带来新挑战。基于此，本文提出计及产消者的激励型需求侧响应（Incentive-Based Demand-Side Response including Prosumers，IBDR-P）下配电网可靠性评估方法。首先利用双层优化构建普通用户和产消者共存的用户最大收益模型，并分析该模型对可靠性评估的影响；接着提出计及配电网满意度可靠性评估的指标SDSR（Satisfaction with Demand-Side Response，SDSR）与计及产消者相对波动率的可靠性评估指标PRV（Prosumer Relative Volatility，PRV）并介绍使用方法；最后基于马尔可夫链蒙特卡洛法利用指标SDSR和指标PRV对IEEE RBTS-Bus6模型进行可靠性评估。算例结果表明，产消者在夏季能发挥提升可靠性的最大效用，但同时也存在最突出的潜在波动风险。

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.

Key words: Incentive-based demand-side response, Distribution network reliability, Prosumer, Markov chain Monte Carlo
