Increasing building`s self-sufficiency rates through PV plus storage hybrids

Decarbonizing the building stock is of utmost importance for achieving sustainability as buildings are holding an important role for the clean energy transition. In this paper, the impact on the electrical consumption and building related CO2 emissions are analysed through real measurements by taking the effect from the implementation PV plus battery energy storage hybrids within 5 residential buildings in Plovdiv area. Increased self-sufficiency rates are quantified for a period of 3 years under pure self-consumption mode, where no power sells are taking place. Indicators such as monthly and yearly self-sufficiency rates with and without storage are compared. Building`s related CO2 avoidance are also compared in two scenarios-with and without battery energy storage system.
