Dr. Sovannarith Leng was born on August 6, 1982, in Phnom Penh, Cambodia. He completed his primary and secondary education in Phnom Penh before pursuing higher education in electrical engineering at the Institute of Technology of Cambodia, where he graduated with a Bachelor of Engineering in Electrical Engineering in 2006. Following his undergraduate studies, Dr. Leng was awarded the prestigious AUN/SEED-Net scholarship to continue his graduate education at the Faculty of Engineering, Chulalongkorn University, where he obtained his Master of Engineering degree in 2008, specializing in electrical power systems. From 2008 to 2013, Dr. Leng served as a lecturer at the Institute of Technology of Cambodia (ITC), teaching courses in electrical power systems, power system analysis, and related engineering disciplines. During this period, he also contributed to the modernization and enhancement of Cambodia’s electrical engineering curriculum to better align with the country’s rapidly evolving power sector and growing energy infrastructure needs. In 2013, Dr. Leng was awarded the Erasmus Mundus scholarship by the European Union to pursue doctoral studies at Toulouse III - Paul Sabatier University in France. He completed his Doctor of Engineering degree in 2016, with research focused on advanced power system operation and stability analysis. Dr. Leng currently serves at Electricité du Cambodge (EDC) as Deputy Director of the Transmission Department, overseeing the National Control Center (NCC), which is responsible for the real-time operation and reliability of Cambodia’s national power system. In his current role, he leads teams responsible for: • power system operation planning, • transmission system analysis, • contingency and disturbance assessment, • grid reliability and stability studies, • and operational coordination of Cambodia’s interconnected power network. His work is particularly significant during Cambodia’s ongoing energy transition, as the country increases the integration of renewable energy sources, especially solar power, into the national grid. Dr. Leng has been actively involved in addressing the operational and technical challenges associated with variable renewable energy (VRE) integration, system flexibility, and grid stability in weak-grid and low-inertia operating conditions. In recent years, his work has also focused on the integration and operational assessment of Battery Energy Storage Systems (BESS) to support Cambodia’s evolving power system needs. This includes applications related to: • frequency regulation, • spinning reserve replacement, • voltage support, • renewable energy smoothing, • and grid-forming capabilities for improving system resilience and stability. Dr. Leng has contributed to technical evaluations and operational planning associated with integrating large-scale BESS into Cambodia’s transmission network as part of the country’s broader transition toward a cleaner, more flexible, and more reliable power system. With extensive experience spanning academia, system operation, transmission planning, renewable integration, and energy storage technologies, Dr. Leng is recognized for his practical expertise in power system stability, modern grid operation, and the deployment of advanced technologies to support sustainable energy transition in frontier power systems.
