新型电力系统电力电量平衡分析关键技术与研究框架
Key Technologies and Research Framework for the Power and Energy Balance Analysis in New-Type Power Systems
摘要
Abstract
With the accelerated construction of new types of power systems,the proportion of integrated renewable energy sources has increased rapidly. Achieving an accurate,efficient,and practical power balance analysis under strong uncertainty of the source and load is a basic theme in the dispatching,controlling,and planning of new power systems. Hence,the shortcomings of current research in the description and calculation of the balance state are reviewed by summarizing the research objects,analytical models and methods,evaluation indices,and applications of power and quantity balance analyses. Based on the two key scientific issues of "electric power and energy balance state description under strong randomness and strategy" and "electric power and energy balance analysis and calculation under the centralized regulation-coordination autonomous balancing mechanism," a research theoretical system for electric power and energy balance is proposed. First,this system covers "balance boundary generation-balance analysis and calculation-balance state assessment-balance early warning-balance capacity improvement." Then,research ideas and technical schemes are proposed,including random balanced scenario generation,multi-period coordination decoupling balanced analysis,balanced state evaluation index system design,multi-spatial-temporal hierarchical balanced early warning,and balanced cooperation mechanism construction. Finally,some key technologies are worthy of consideration in further research on electric power and energy balance analyses in new types of power systems.关键词
