PV self-consumption improvements with energy flow management and storage - Case of solar home in the north of Algeria.

This paper discusses the impact of the combined action of storage and energy distribution management on the improvement of self-consumption in the residential sector. The case study is a house that is equipped with a photovoltaic system with backup and connected to the network. Several configurations of the PV-batteries system were considered in order to determine the optimal configuration to satisfy the energy demand of the house located in the north of Algeria. An energy management strategy based on the availability of photovoltaic energy and the state of charge and discharge of the battery was implemented and analyzed over a one-year period. The obtained results show that the storage improves the rate of selfconsumption by 20 to 40% according to the seasons.
