Impact of Power Quality of Microgrids with High Penetration of Renewable Energy on the Characteristics of LED Lamp

Microgrids are an increasingly popular solution for providing communities and facilities with a reliable, efficient, and resilient energy supply. In a microgrid, several energy sources are combined to form a small self-contained grid that can operate independently of the main grid. Renewable energy sources such as solar, wind, and hydropower are playing an increasingly important role in microgrid design due to their environmental sustainability, cost-effectiveness, and ability to provide a reliable energy supply. However, integrating renewable energy sources into microgrids can pose technical challenges, particularly regarding the electrical equipment within the system. This study aims to explore the effects of power quality on the performance of electrical equipment, specifically LED lamps, within microgrids that feature significant integration of renewable energy sources. Simulation testing will be carried out using the microgrid model in the electric power system simulation software (OPAL-RT) scenario. The output voltage from the microgrid simulation was used to power the LED lamps, and the light emitted by the lamps was analyzed using a spectrophotometer. The results showed that voltage and frequency fluctuations affect the power consumption and efficiency of LED lights in the microgrid, which can affect the overall system performance, stability, and possibly the lifetime. This study provides insight into the challenges and opportunities in integrating renewable energy sources into microgrids and can contribute to sustainable development in the energy sector.
