<![CDATA[A Power losses in medium voltage distribution networks remain a significant concern for utility companies, particularly in developing regions. This study presents an analytical investigation into the role of control systems in minimizing power losses within the 20 kV medium voltage distribution network at PT PLN (Persero) ULP Balige. This paper research focuses on identifying key components contributing to energy losses, such as unbalanced loading, reactive power flow, and suboptimal voltage regulation. A control system approach is analysed through simulations and system performance evaluations, involving the implementation of automatic capacitor bank control, transformer tap changers, and load balancing strategies. Using simulation tools such as ETAP and actual operational data from the Balige, distribution network, the study evaluates system behaviour under various control scenarios. The results show that implementing a responsive and automated control system significantly reduces technical losses, improves power factor, and enhances voltage profile stability across the network. The study concludes that an integrated control strategy tailored to the characteristics of the local network can optimize distribution efficiency and reduce operational costs. This research provides practical recommendations for PT PLN and similar utilities seeking to modernize their distribution infrastructure through smarter control technologies and data-driven planning.]]>
