风光互补电动汽车储能电站系统优化设计

Optimization design on electric vehicle storage power station system of hybrid wind/PV

通过对唐山市区太阳能和风能资源状况调查分析,对全年不同方位角和倾角上的太阳能辐射量进行模拟计算,得出南偏东9.8°方向、倾角为39.7°的倾斜面上接收的太阳能辐射量最大,其值为1.62×106Wh/m2。研究中对3kW风力发电机和1kW光伏发电系统的发电量进行了计算,并以1辆纯电动轿车为负载进行了容量配比优化,设计了风力发电系统、风光互补系统及光伏系统三种不同的方案,经过对各方案的经济性、可靠性及稳定性分析,得出最佳的设计方案为风光互补发电系统,该系统风力发电装机容量为3kW,光伏发电装机容量为8.96kW。

Based on the investigation and analysis on the Tangshan area of solar and wind energy resources,having taken a numerical simulation on the amount of incident solar energy at different azimuth angles and tilt angles during the whole year,we got that the inclined surface whose azimuth angle was south by east 9.8°and tilt angle was 39.3°could maximum receive solar radiation,which is 1.62×106Wh/m2.In this study,the generating capacity of 3kW wind generator and 1kW photovoltaic power generation system are calculated,and there are three different system design scheme has been put forward for pure electric sedan for load: wind power generation system,wind/photovoltaic hybrid generation system and photovoltaic power generation system.After the plan economy,reliability,stability analysis,the results show the system the best plan of design is wind/PV hybrid system.This moment,the installed capacity of wind power generation system is 3kW and the installed capacity of photovoltaic power generation system is 8.96kW.
