Wind and Solar Hybrid Power Generation for DC grid

Abstract

The creation of a DC microgrid employing a hybrid wind-solar power system for LED street lights and a sporadic power system is the subject of this study. All of them are free and plentiful. The usage of wind-solar hybrid power systems and LED lighting helps reduce electricity costs while increasing energy efficiency. The system's goal is to utilize wind, solar, DC storage (battery), LED lighting, and a controller with maximum power point tracking [MPPT] for solar power, a PID controller for operational charging/dispatch for wind power, and LED dimming control for energy conservation to monitor the system's performance and maintenance. By utilising a timer, all of the LED bulbs will automatically light up between the hours of 6:00 PM and 6:00 AM, using up to 90% less energy than incandescent lamps. Utilizing a timer and dimming controls, 50% of light can be achieved from 10 PM to 6 AM. The suggested technology continuously overcharges the battery to safeguard it from over- or under-voltage while also focusing on energy conservation. Using MATLAB simulation, the proposed system was examined with regard to the battery voltage and the hybrid input power's operational state. By simulating using MatLAB/Simulink, the hybrid system is identified.
