Modelling and Simulation of Grid-Connected Solar-Hydro based Hybrid Power System

In this paper DC linked, grid connected solar/hydro hybrid system is modelled and simulated. A control scheme is developed for solar and hydro system for variable solar irradiance and variable load. Synchronous generator based hydro system is used to feed bulk of the power and whenever solar irradiance is available solar system along with hydro system and grid supply to the load. The performance analysis of the proposed HES and its power management strategy has been done using the simulink toolboxes of MATLAB software. The proposed system consists PV system hydro system, battery and grid. In some remote/rural areas, it is very difficult to satisfy the demand of electrical power throughout the year with the power grid. In such areas, the power requirement can be fulfilled by renewable energy system such as hydro or PV system. Either the hydro system or PV system is not capable of supplying power requirement throughout the year as both systems are intermittent. Hence, the judicious combination of hydro and PV system has been modeled for electrification. The power management strategy is modeled to manage the power flow of the energy systems to fulfill the load demand. The presented results clearly show that the proposed HES and its control strategy are suitable for implementation in remote/rural areas.
