Study on the Configuration and Operation Modeand Influence Factors of an Integrated PowerGeneration System of Wind, Photovoltaic andEnergy Storage Unit

风光储发电系统是大规模的集风力发电、光伏发电和储能为三位一体的可再生能源工程.本文重点对风光互补出力特性、储能系统特性和风光储联合发电系统特性进行介绍;介绍了风光储联合发电的六种组态运行模式及不同的模式切换条件;基于灰色关联度分析法分析了风光发电与基地环境因素的关联大小,为风光发电功率预测做了基础工作.风光储组态运行模式满足新能源并网要求,对新能源发展具有巨大的推动作用.

The Integrated Power Generation System of Wind, Photovoltaic and Energy Storage Unit is a large-scale trinity of renewable energyprojects. This paper focuses on introducing the complementary output characteristics of wind and photovoltaic, characteristics of energystorage system and wind power generation system; introduces the six kinds of configuration modes of an Integrated Power GenerationSystem of Wind, Photovoltaic and Energy Storage Unit and different conditions of mode switching; analyzes the correlation betweenwind-solar power and environmental factors based on gray correlation analysis method which will do the basic work for the powerforecasting. The configuration and operation modes of the unit can meet the requirements of new energy sources connecting the grid, andhas a huge role in promoting the development of new energy resources.
