Coordinated Supply of Solar and Wind Energy Using MPPT to Power Micro-Grids along with Battery

Harris B. Mathews, Soumya Saraswati

Abstract: Wind and solar energy are two of the most feasible non-conventional energy sources due to their availability and environment friendly nature. Research has been done on operating both the energy sources alongside one another in order to take advantage of their complementary characters and leading to improve in efficiency and power dependency. Simulation analysis and experiments show that the hybrid system is able to capitalize the correlative nature of the two energy sources, and deliver energy reliably yearlong. A wind-PV hybrid power station is more beneficial than an individual wind or PV power station because when one system is faulted other can supply the power. Maximum Power Point Tracking (MPPT) system with Perturb And Observe (P & O) algorithm is used, which extracts maximum power from the PV system and wind system. Bi-directional converter is utilized to store DC power in battery bank and supply power to the micro-grid by converting the DC power into AC power. Hybrid generation systems are more conventional than making use of a single source to generate power that matches the requirements. Therefore by using both the power sources in parallel, power is extracted from the source which provides a higher output power at a given time. The process of battery getting charged and power supplied to the micro-grid is done simultaneously by any one of the sources. And the battery can be discharged to supply power directly when both PV and wind turbines aren't able to provide sufficient power to the grid. By using hybrid power stations higher generating capacities and uninterrupted power transfer to the micro-grid can be easily achieved. In this work, a coordinated supply of wind and solar energy would have been implemented to assure a continuous supply of power at the load end and the system is simulated using MATLAB.
