Techno-Economic Case Study of Micro-Grid System at Soccer Club of Skagerak Arena Norway

subject

description

The photovoltaic system and battery energy storage can be used in a microgrid system for reducing peak demand from the grid and it enhances overall techno-economic performance of the system. In this work, a functioning micro-grid of 800 kWp photovoltaic system and 1 MWh lithium ion battery, located at Soccer Club of Skagrek Arena (Norway), is used for techno-economic analysis and operational load from years 2015 to 2018. The system performance has been analyzed for understanding the techno-economic operation, and contributions from the PV and battery energy storage for reducing peak demand from the grid. In this study, it has been observed that the integration of PV and battery energy storage can reduce the peak demand by 33%, whereas the micro-grid system electricity cost and net present cost have increased by 28% and 39% respectively compare to grid tied supply system. To reduce grid peak demand, the battery energy throughput has been following the same pattern as saving from grid supply. It has been noticed that the energy saving during summertime is nearly two times more as compare to wintertime. Results from this work are going to contribute for developing an institutional micro-grid facility considering demand side management and grid constraints.
