Economic performance assessment of building integrated photovoltaic system with battery energy storage under grid constraints

subject

description

Abstract In this work, a typical South Norwegian house with BIPV system is considered for potential application of on-site battery energy storage. Economic and technical operation performance analysis has revealed that such a system can perform techno-economically much better compared to its counterpart. Techno-economic performance of BIPV system with appropriate energy storage has been evaluated for grid power supply limits with appropriate energy tariff for minimizing the annualized energy cost. It has been assumed that the capital costs associated with PV has been included in the building mortgage and expected that in the near future, the grid power supply limits would be introduced and therefore the BIPV house owner may need to install the battery with additional investments and it may affect the techno-economic performance of the BIPV energy system. It has been observed that during month-wise appropriate grid power supply limits, battery with BIPV system can perform much better through energy throughput compare to other reported scenarios. The correlation analysis has been presented for techno-economic performance indicators and observed that there is a strong correlation among PV energy production and grid energy supply. Correlation analysis among the technical and economic performance indicators may be useful for techno-economic of BIPV system.
