合肥地区户用光储直柔系统设计

Design of Household Photovoltaics andEnergy Storage DC Flexible System in Hefei

为了解决农村户用光伏发电与农户用电不匹配的问题,采用户用光伏和光储直柔的方案,对合肥地区的地理气候、户用能耗进行调研,利用PVsyst软件设计出户用光伏发电系统,并将其与光储直柔系统的设计依据相结合,初步设计了户用光储直柔系统。通过SAM软件进行模拟,从技术经济的角度确定了系统内储能电池的类型和容量,并对系统进行了经济分析,验证了在合肥农村使用户用光储直柔系统的可行性。

In order to solve the mismatch between rural household photovoltaic power generation and farmers'electricity consumption,the scheme of household PEDF(photovoltaics,energy storage,direct current,flexibility)was adopted to design a household PEDF system in Hefei.Firstly,the geographical climate and household energy consumption of Hefei were investigated.Then PVsystsoftware is used to design the household photovoltaic power generation system,and it is combined withthe design basis of the PEDF system to design the household PEDF system.Finally,SAM software is used to simulate,the type and capacity of energy storage battery in the system are determined from the technical and economic point of view,and the economic analysis of the system is carried out.The results show that it is technically and economically feasible to implement household PEDF system in Hefeirural areas.
