Software Design And Application Of BIPV Systems

As the world economy developing and population growth,the traditional fossil energy can't meet the demand of human's production life;renewable energy technology has become particularly valuable.With the development of photovoltaic power generation,the reasonable and high effect utilization of solar rational are faced with some problems.Photovoltaic building integration(BIPV)requires not only the function of external enclosure,but also independent power for construction purposes.BIPV using renewable solar energy is a green building technology;it is a new concept of producing energy.In this paper,PVsyst and HOMER are integrated for the PV energy balance and economical design of BPIV.It analyzes how to get the most efficient use of energy,and gives the corresponding configuration scheme.This paper's research on BPIV software design was based on Tianjin University's Sun room(SunFlower).First of all,this paper introduced the geographical environment,climatic conditions of the location of the PV system,and the electrical equipment and photovoltaic power generation system topology of the system.Secondly,the photovoltaic power generation system was designed by PVsyst.The required capacity of PV modules,energy storage capacity of the battery,the system's production and consumption of electricity and the energy balance in a year were calculated and simulated.Then,the daily generating capacity and power consumption as well as the change of the battery charged state of photovoltaic power generation system with accumulator system were simulated by HOMER,and the micro-grid system's initial cost and operating cost economy in two different battery energy storage case were calculated,the best match PV modules and battery capacity was obtained.Finally,an empirical analysis of SunFlower was analyzed based on the data acquisition system,the error between the measured and simulation data was compared by data for 12 months,and the errors were analyzed.Combining PVsyst and HOMER in BPIV configuration program in the photovoltaic micro-network,the best scheme can be provided for decision makers,such as managers or contractors in the early design process.
