Optimal sizing of domestic grid-connected microgrid maximizing self consumption and battery lifespan⋆

The research work presented in this paper consists of making an individual house partially autonomous by installing local renewable production resources. Photovoltaic panels, wind turbine, and batteries are optimally sized for household self-consumption and batteries lifespan maximization using Sequential Quadratic Programming (SQP) method. Simulations using real meteorological data from two cities, namely Brest in France and Algiers in Algeria, are presented and discussed to study the continuity of service, the achieved energy self-sufficiency, and lifetime of the battery for both cold and hot climate. The simulation results show that the grid-connected domestic PV-Wind-Battery based microgrid is reliable and cost-effective in the long term. Copyright (C) 2022 The Authors.
