兼顾物理状态与任务需求的广义灵活负荷可信功率/能量灵活性统一建模及量化
Unified Modeling and Quantification of Credible Power/Energy Flexibility for Generalized Flexible Loads Considering Physical States and Task Demands
摘要
Abstract
Evaluating and quantifying the flexibility of load-side resources is an essential prerequisite for guiding their participation in grid regulation and ensuring power supply-demand balance.However,generalized flexible loads exhibit diverse operating mechanisms and regulation modes,and are affected by various uncertain factors.At present,there is a lack of unified,credible flexibility modeling and analysis methods,making it difficult for the grid to effectively support the unified management of different load types.To address this issue,this paper analyzes the formation mechanism of flexibility for various flexible loads under task-demand and physical-state constraints.Aiming at power grid dispatch objectives and based on the power/energy boundary model,this paper proposes a unified evaluation method for the flexibility of diverse flexible loads that considers physical states,task demands,and the impacts of uncertain factors.An evaluation index for flexibility is established based on credible power/energy boundaries,enabling solutions for diverse flexible loads,including both distributed and centralized.Taking typical loads such as electric vehicles,thermostatically controlled loads,and industrial loads as objects,the evaluation results of the typical bounds are verified.Finally,case studies are constructed to validate the effectiveness of the proposed model across various typical flexible loads,while the impact of task demand variations on load regulation capabilities is also analyzed.关键词
