Micro grids are inclined to use renewable energy sources within the availability limits. Energy storage improved the management of hybrid energy resources used in parallel with the grid. This study models the hybrid usage of wind and solar energies as a support for the grid with the availability of batteries. A mixed integer mathematical model is proposed to schedule the use of different resources minimizing the cost following the power market. Capacity, energy balancing and demand constraints are taken into account for this purpose. This model can be used as a decision support system for micro grid load planning.
