Abstract：Taking the residential buildings in a rural area of Xi'an as the research object,a household solar distributed photovoltaic grid-connected power generation system is established.The self-sufficiency rate(SSR)and self-consumption rate(SCR)are adopted as technical indicators,and the optimized levelized cost of electricity(LCOE)technology is adopted as an economic indicator.The performance of building-integrated photovoltaics(PVBG)systems under different photovoltaic and battery sizes is evaluated and analyzed to obtain the optimal combination of photovoltaic and battery systems.The results show that when the LCOE is 0.035～0.438 yuan/kWh,the optimal sizes of photovoltaic and battery are 5 500 Wp and 3 000 Wh,respectively.
