Providing an optimization scheme for energy planning in a micro grid connected to the residential grid

This paper proposes a control scheme to estimate the operating cost of a grid-connected micro grid supplemented by a battery energy storage system. By modelling battery degradation as a function of discharge depth and discharge rate and converting the incremental capacity loss per cycle into the associated cost, the objective function is defined and solved using GAMS. Simulation results are presented to verify the proposed approach that the proposed optimization scheme can easily manage the DG units in a way that reduces the operation cost and meets the constraints and objectives of the existing system.
