Simulation of photovoltaic systems electricity generation using homer software in specific locations in Serbia

Abstract

In this paper basic information of Homer software for PV system electricity generation, NASA - Surface meteorology and solar energy database, RETScreen, PVGIS and HMIRS (Hydrometeorological Institute of Republic of Serbia) solar databases are given. The comparison of the monthly average values for daily solar radiation per square meter received by the horizontal surface taken from NASA, RETScreen, PVGIS and HMIRS solar databases for three locations in Serbia (Belgrade, Negotin and Zlatibor) is given. It was found that the annual average values of daily solar radiation taken from RETScreen solar database are the closest to the annual average values of daily solar radiation taken from HMIRS solar database for Belgrade, Negotin and Zlatibor. Monthly and total for year values of electricity production of fixed on-grid PV system of 1 kW with optimal inclinated and south oriented solar modules, in Belgrade, Negotin and Zlatibor using HOMER software simulation based on data for daily solar radiation taken from NASA, RETScreen, PVGIS and HMIRS databases are calculated. The relative deviation of electricity production of fixed on-grid PV system of 1 kW using HOMER software simulation based on data for daily solar radiation taken from NASA, RETScreen, and PVGIS databases compared to electricity production of fixed on-grid PV system of 1 kW using HOMER software simulation based on data for daily solar radiation taken from HMIRS databases in Belgrade, Negotin and Zlatibor are given.

Photovoltaic Geographical Information System module for the estimation of solar electricity generation: A comparative study in Khyber Pakhtunkhwa Pakistan

“…The daily electricity production as well as global irradiation for all the districts are recorded as maximum from March until October months and minimum during January, February, November and December. The results are in agreement with the studies carried out for different countries around the world [10,[21][22][23][24][25][26][27][28]. Figure 3 shows the mean monthly electricity generation (Em) as well as the monthly mean global irradiation per square meter (Hm) for the six districts of Khyber Pakhtunkhwa.…”

“…Therefore it was concluded that PVGIS prediction is suitable for longer periods such as one year but not appropriate for single months [26]. More studies around the world discussed similar results [2,[9][10]20,[27][28][29]. Figure 4 depicts the estimated electricity production (kWh) per year from a PV system for the six districts of Khyber Pakhtunkhwa, Pakistan.…”

Technical and economic analysis of grid-connected PV/Wind energy stations in the Republic of Serbia under varying climatic conditions

“…In the paper [27] were analyzed solar energy resources from different databases. The results show significant differences in the values of solar energy obtained using a different solar database.…”

Feasibility Study of a Grid‐Tied Photovoltaic System for Household in Pakistan: Considering an Unreliable Electric Grid

“…The study reported that the unreliable grid consideration increased the cost of energy (COE) as compared to 24 h availability of the grid. Beside these, several studies are carried out for grid connected PV [23][24][25][26] and PV-wind-diesel hybrid power systems [27][28][29][30][31].…”
