Management and Control of a Grid-Connected PV/Tidal Hybrid System with Energy Storage

This work presents an optimal management strategy for a grid-connected PV/tidal hybrid system with energy storage. The considered system, dedicated to supplying electricity to a factory, includes a photovoltaic generator, a tidal turbine, and a bank of lithium-ion batteries for energy storage. The suggested configuration enables various sources to supply power to the load either independently or concurrently, contingent upon meteorological conditions. In response to demand, batteries facilitate the storage of surplus energy generated or provide power to the load during adverse meteorological conditions. To do this, we first present the modeling of the different sources equipped with MPPT controls allowing their production to be maximized. In the second part, an energy management algorithm is developed to guarantee a consistent allocation of energy transfers between the sources and the batteries. The manager is finally implemented in the MATLAB/Simulink simulator, The assessment of the complete hybrid system's functionality has been conducted. The results indicate that the proposed system represents a viable solution for sustainable applications.
