Voltage and power regulation in a solar-wind hybrid energy system

This paper presents the analysis of power to observe the reliability of a solar-wind hybrid energy system which consist of a Photovoltaic (PV) array, a wind turbine, a Permanent Magnet Synchronous Machine (PMSM), a three phase diode bridge rectifier, a LTC3784 controller, a grid interface inverter, a step-up transformer and a low-pass LC filter. The power from solar-wind hybrid system is combined and then the output from here is transferred to the controller LTC3784 for a fixed output voltage which is then inverted using an SPWM-based full-bridge inverter, and stepped up using step-up transformer to feed into the utility grid. Both input and output power has been verified to check the reliability of the system. The proposed model is mathematically designed and simulated by PSIM and LTspice software. The simulation results show the effectiveness and reliability of the designed solar-wind hybrid energy system.
