This work proposes an optimization method for
the management of a Battery Energy Storage System (BESS)
integrated in an islanded Micro-Grid, including Renewable
Energy Systems (RESs) and generators burning fossil fuels. The
optimized control of the battery State of Charge (SOC) allows to
get the BESS available as much as possible to support the RES
power production, hence minimizing the use of fossil fuels. The
optimization of the BESS is based on load demand and RES
production forecast. The Optimization Algorithm that has been
adopted is the Linear Programming, using the method of the
Interior Point.
