Cost Optimization Based on a Linear Programming Approach for a Hybrid Renewable Energy System

The objectives of the studies presented here are to develop an efficient method adapted to the energy production of an isolated hybrid power system located on the island of Djerba, Tunisia. To this end, we have proposed two optimization methods, based respectively on linear programming (LP) and software (HOMER), with the aim of minimizing the energy cost of the hybrid system while respecting constraints linked to all the elements of the system. We therefore compared the two optimization strategies. The proposed linear program yields an electricity cost of 0.206$/kWh, lower than the HOMER cost of 0.308$/kWh. This system would therefore have advantages in terms of energy independence in particular.
