Sustainable building for the quality of power supply

The photovoltaic (PV) systems, together with energy storage devices, interconnected in parallel with the utility can improve the reliability during power quality perturbations in the main system supply. The paper presents a possible solution with high level of power supply continuity, where a hybrid system is simulated in case of power quality negative events. Reference is made on an existing plant relevant to a case of building integrated PV system installed in Italy. An economic analysis is also developed in order to weigh also the power quality aspect into the revenue indices.
