Matching Photovoltaics Generation with Commercial Load Profiles – Case From Central Sweden Jurasz J*, Wallin F, Dąbek P. B.

Abstract

Cities evolved to be major energy consumption centers. However, their potential to generate electricity from renewables is in most cases constrained to photovoltaics. Therefore, transforming them into sustainable and self-sufficient urban areas is a challenging task. In this preliminary study, we have investigated the match between photovoltaics (PV) generation and electrical load of five commercial buildings located in Sweden. First, the rooftop PV potential was assessed. Secondly, the optimization was performed aiming at reducing the energy flow between building/buildings and local electrical network. Results indicate that from the perspective of minimal power flow (for single buildings) optimal are PV system oriented to the southeast and southwest with a relatively small tilt angle of 15°.
