基于源荷两侧不确定的虚拟电厂灵活性调整建模及调度策略
Modeling and Scheduling Strategies for Flexibility Adjustment in Virtual Power Plants Considering Source and Load Uncertainties
摘要
Abstract
To address the insufficient flexibility of grid operations caused by the uncertainty of high-penetration renewable energy output and inflexible load regulation,this paper proposes a solution that integrates flexible resources,such as green power to hydrogen and synthesis methanol systems,into a virtual power plant(VPP)for demand response and flexibility standby.First,a regulatory standby model for green power to hydrogen and synthesis methanol systems and other flexible resources is established.Considers source and load correlation to quantify VPP flexibility demand,addressing source and load mismatches and fluctuation errors.Second,to optimize the flexibility adequacy of the VPP,a method for quantitative indicators of adequacy and its probability is proposed based on the historical cumulative distribution function of flexibility,enhancing regulatory capabilities.Lastly,to reflect the competitive interests among VPP participants,a master-slave game model is designed,with the VPP operator as the leader and the load aggregator as the follower.This model facilitates the determination of VPP clearing prices and flexible resource consumption strategies for each time through interactive competition.Example analyses demonstrate that the proposed model is reasonable and feasible,the algorithm is straightforward and has significant implications for guiding engineering practice.关键词
