In a groundbreaking study published in the Ain Shams Engineering Journal, researchers have explored innovative methods to enhance the performance of a 7 MW solar power plant in Thailand, focusing on critical aspects of grid stability and energy management. The research, led by Chattariya Sirisamphanwong from the Department of Physics and General Science at Nakhon Sawan Rajabhat University, highlights the challenges and solutions associated with integrating renewable energy sources into existing power grids.
The study emphasizes two key strategies: reactive power control and energy time shift combined with voltage range control, both of which aim to maintain grid voltage within acceptable limits. The findings reveal that while the reactive power control method effectively stabilized the grid voltage, it came at a significant cost—resulting in a reduction of energy generation by over 5,600 MWh. Sirisamphanwong noted, “Our research illustrates the delicate balance between maintaining grid stability and maximizing energy output. The trade-offs we observed are crucial for energy providers to consider.”
Conversely, the energy time shift mode demonstrated remarkable efficacy in meeting grid load demand, achieving an impressive 99.98% match. This approach, however, required the integration of a Battery Energy Storage System (BESS), which, while effective, also extended the system’s payback period due to the additional investment costs involved. The voltage range control method also showed promise, meeting 68.75% of grid load demand while ensuring voltage stability.
The implications of this research are significant for the energy sector, particularly as countries like Thailand continue to ramp up renewable energy deployment. With the global push toward sustainability, understanding how to optimize solar energy production while maintaining grid integrity is paramount. “This study could serve as a model for future solar projects, helping to refine strategies that minimize costs while maximizing efficiency,” Sirisamphanwong added.
As the energy landscape evolves, the integration of advanced technologies like BESS will be critical for enhancing the reliability of renewable energy systems. The research not only contributes to academic discourse but also provides practical insights that can influence policy and investment decisions in the energy sector.
