研究目的
The aim and novelty of this study is the development of a gridded model to analyse the performances of PV systems, which includes techno-economic optimization of PV systems, integration with energy storage, and environmental aspects. The optimization model can also be used to maximize economic or environmental targets, and thus support the strategic management of PV and storage systems.
研究成果
CM SAF SARAH-2, Engerer2, and Perez1990 have shown the best performances among the irradiance databases, decomposition and transposition models, respectively. STR?NG resulted in the second-best irradiance database among those investigated when comparing hourly global horizontal irradiance with weather station data. The spatial maps generated by the developed model provide an important tool for better understating and improving the integration of PV systems and batteries in the building sector thus providing timely information on the technical, economic and environmental performances of PV systems using a spatial approach.
研究不足
The study focuses on Sweden, but the model has a generic validity and can be used for spatial assessments of PV systems applications globally by using satellite derived gridded data. The model structure can also be used for other energy applications, such as the estimation of building energy consumptions, and in general for energy systems evaluations that require gridded analyses.
