研究目的
To compare the performance of PV power simulation software (PVsyst, PV*SOL, and HOMER) with an installed PV plant at the University of Campinas, aiming to provide data for future comparisons and analyze the accuracy and peculiarities of each software.
研究成果
The study concluded that PVsyst, PV*SOL, and HOMER performed well in simulating the PV plant's power generation, with PVsyst providing the most accurate results, PV*SOL being more conservative, and HOMER showing optimism. The installed PV plant worked as designed, generating energy close to the simulated values. The peculiarities of each software were highlighted, contributing to the selection of appropriate software for future PV projects.
研究不足
The study is limited by the availability of real data from the installed PV plant, with only four months of data (May to August) used for comparison. Additionally, the accuracy of the software may vary according to month, location, and installation specifics.
1：Experimental Design and Method Selection:
The study involved simulating the largest PV plant at the University of Campinas using three different PV power simulation software (PVsyst, PV*SOL, and HOMER) to compare their performance with real data from the installed PV system.
2：Sample Selection and Data Sources:
The solarimetric database was standardized using Meteonorm for all simulations to eliminate error differences involving solarimetric databases.
3：List of Experimental Equipment and Materials:
The PV system setup included 1248 Canadian CS6K-270P photovoltaic modules and 5 Ingecon Sun 55TL PRO inverters, totaling a
4：96 kWp system. Experimental Procedures and Operational Workflow:
3 The simulations were based on the project details before the PV plant installation, and monthly data from the installed PV plant were collected for comparison.
5：Data Analysis Methods:
The performance of the software was analyzed using figures of merit such as Final Yield (Yf), Performance Ratio (Pr), and Energy Delivery (ED), comparing simulated results with real data from May to August.
