高比例水电新型电力系统理论模型探索

Theoretical Model Exploration of New Power System with High-proportional Hydropower

着眼于部分省份丰富的水电资源禀赋,探索高比例水电新型电力系统理论模型。首先,分析了其发展定位和价值内涵,创新将“源网荷储”四要素扩展为“源网荷储脑”五要素,并以水能富集地区典型省份四川为例,详细分析了各要素的基本内涵及关联关系;然后,构建了高比例水电新型电力系统的理论模型框架并分析了其演变趋势;最后,基于理论模型分析了四川新型电力系统发展目标和演化路径,介绍了四川新型电力系统初期探索实践的基本思路,为全国范围内水能富集地区新型电力系统构建提供参考。

Focusing on the characteristics of rich endowment of hydropower resource in Sichuan and similar provinces,the exploration for theoretical model of new power system with high-proportional hydropower(HHNPS) is carried out.Firstly,the development orientation and value connotation of HHNPS are analyzed.The basic connotation and correlation relationship of five key elements of new power system,namely "source-grid-load-energy storage-intelligens",are proposed and analyzed.And then,the theoretical model framework of HHNPS is constructed and its evolution trend at different development stages are analyzed.Finally,the basic ideas of initial exploration and practice for new power system in Sichuan are introduced,which can provide a reference for the construction of new power system in similar areas nationwide.
