Output regulation of hybrid renewable energy system through hysteresis control

Sreejith S.

Abstract


This paper proposes a hybrid energy conversion system combining photovoltaic and wind turbine as a small-scale alternative source of electrical energy where conventional generation is not practical. The hybrid system consists of photovoltaic panels, wind turbines and storage batteries. A new system configuration of the front-end rectifier stage for a hybrid wind/photovoltaic energy system is presented in the paper. It allows configuration allows the two sources to supply the load separately or simultaneously depending on the availability of the energy sources. The inherent nature of this Cuk-SEPIC fused converter, additional input filters are not necessary to filter out high frequency harmonics. Harmonic content is detrimental for the generator lifespan, heating issues, and efficiency. Controller is used to regulate the output voltage inspite of the input variations. Simulation and hardware results are given to highlight the merits of the proposed circuit.

Key Words- Hybrid energy system, Renewable, Cuk-SEPIC, Photovoltaic, Wind energy
