ITS Campus, ITS News — The lengthy electricity distribution channels often result in significant power loss and voltage drops. To address this issue, a recent doctoral graduate from the Department of Electrical Engineering at Institut Teknologi Sepuluh Nopember (DTE ITS) has proposed a distribution network optimization system through the integration of Distributed Generation (DG).

During his Doctoral Promotion Session at DTE ITS on Monday (12/8), Dr. Sujono ST MT explained that DG is a system that places small-scale power generation units closer to the load center. These generation units can be based on renewable energy sources such as solar, wind, or biomass. According to Sujono, this system can improve voltage stability and network efficiency while reducing the power flow from the main grid.

Sujono further explained that when the distribution network is disconnected from the main grid, an optimally positioned DG can maintain a continuous power supply to critical loads. This ensures the safety of vital loads that cannot tolerate power interruptions. “DG also has relatively low operational costs, offering significant profit potential,” he said.

The Karanganyar native added that his DG integration optimization approach utilizes approximation methods by applying metaheuristic algorithms. Sujono explained that these algorithms are used to find optimal solutions for complex optimization problems. “These algorithms are also part of artificial intelligence,” added the researcher.

The algorithms employed by Sujono include the Grey Wolf Optimizer (GWO), Particle Swarm Optimization (PSO), Differential Evolution (DEA), and the Adaptive Modified Firefly Algorithm (AMFA). Among these, Sujono noted that the AMFA-DE algorithm is the most effective in delivering optimal results for DG optimization. “This algorithm can find more accurate and efficient patterns in complex data sets,” he stated.

In his development, the lecturer from Budi Luhur University’s Department of Electrical Engineering emphasized that technology in efficient energy conversion systems can significantly enhance DG’s power generation capacity. Affordable, efficient, and reliable energy storage technologies can accelerate DG adoption in meeting electricity demand.

Sujono also highlighted that renewable energy-based DG relies heavily on natural conditions, introducing uncertainty in power generation capabilities. Therefore, he stressed the importance of studies related to predicting DG’s generation potential. He is committed to advancing research on optimizing affordable, efficient, and environmentally friendly energy storage and network protection systems.

Looking ahead, this graduate from Universitas Indonesia’s Master’s Program in Electrical Engineering hopes that the public will become aware of Indonesia’s vast and abundant renewable energy potential. According to Sujono, policies related to renewable energy utilization must be implemented to encourage the use of these resources. “This is crucial for meeting the public’s electricity needs and accelerating the process of energy distribution,” he concluded.
