Grid-source Coordinated Planning Method Considering Multiple Types of Flexible Resources
摘要
Abstract
To ensure the reliability of high-proportion renewable energy system planning,it is crucial to achieve the coordinated utilization of various types of flexibility resources based on their distinct supply characteristics.This paper proposes a coordinated generation and transmission planning method considering multiple types of flexibility resources.First,flexibility supply and demand models on the generation,grid,and load sides are established to quantify the characteristics of different flexibility resources.Based on the principle of flexibility balance and transmission congestion risk,key indices are constructed from three dimensions:flexibility deficit duration,flexibility deficit magnitude,and flexibility balance,enabling a quantitative assessment of system flexibility.Second,a two-stage generation and transmission expansion planning model incorporating multiple flexibility resources is developed,where the upper level represents planning decisions,and the lower level simulates system operations.Finally,the proposed planning method is validated using an improved garver-18 system.The results demonstrate that the coordination of different flexibility resources effectively mitigates grid flexibility shortages and transmission congestion risks.Compared with the traditional flexibility planning method that only considers energy storage and thermal power units on the generation side,the investment cost is reduced by 26.34%.关键词
