In the heart of Indonesia, a groundbreaking study is shedding light on how battery energy storage systems (BESS) can revolutionize the integration of renewable energy sources, paving the way for a more stable and reliable electricity grid. Led by Mudakir Mudakir from Malang State University, the research focuses on the potential of BESS to mitigate the intermittency issues associated with solar and wind power in North Sulawesi and Gorontalo.
The Indonesian government has set an ambitious target to achieve a 23% share of new and renewable energy (NRE) in its national energy mix by 2025. However, the fluctuating nature of solar photovoltaic (PV) and wind turbine (WT) outputs poses significant challenges to grid stability. This is where BESS comes into play, offering a promising solution to smooth out the variability of renewable energy generation.
Mudakir’s study, published in the Journal of Mechatronics, Electrical Power, and Vehicular Technology, employs a combination of technical simulations to assess the performance of BESS in stabilizing voltage and frequency fluctuations within the electricity system. The research includes power flow analysis, transient stability testing, and short-circuit studies, both with and without the integration of BESS.
The findings are compelling. Implementing a 10 MW/5 MWh BESS can significantly reduce frequency deviations, limiting frequency drops to 49.82 Hz during disturbances, compared to 49.67 Hz without BESS. “This improvement is crucial for maintaining grid stability and preventing potential blackouts,” Mudakir explains. Furthermore, BESS helps maintain voltage stability at critical substations by reducing voltage fluctuations by up to 40%.
The commercial implications of this research are vast. As renewable energy sources become more prevalent, the need for reliable energy storage solutions will only grow. BESS can enable a more stable and reliable grid, supporting the development of renewable energy without compromising power quality. This is particularly relevant for regions like North Sulawesi and Gorontalo, which have significant wind and solar energy potential.
The integration of BESS can also lead to cost savings for energy providers and consumers alike. By smoothing out the variability of renewable energy generation, BESS can reduce the need for expensive backup power sources and improve the overall efficiency of the electricity system. This can result in lower energy costs and a more sustainable energy future.
As the energy sector continues to evolve, the role of BESS in supporting renewable energy integration will become increasingly important. Mudakir’s research provides valuable insights into the potential of BESS to stabilize the grid and support the growth of renewable energy. As we move towards a more sustainable energy future, the integration of BESS will be a key factor in ensuring a stable and reliable electricity supply.
