Professor Ir Dr Hazlie Mokhlis FASc is an expert in electrical power systems, a field crucial due to the high dependency on electrical energy across various sectors. He and his research team work on various methods to improve the performance of the electrical energy supply system for planning and operation. He has over 300 publications, an H-index of 63, and 16,426 citations. Among his significant contributions is the identification of lightning strike types in Tenaga Nasional Berhad’s transmission lines for effective mitigation. He also helped UM to reduce electricity costs through the implementation of a distribution system configuration. Building on his expertise, his outstanding contributions led to his appointment to the project advisory committee on the Smart Grid Project in 2019. He was also selected as an expert consultant for the Development of a Replication and Scale Up Plan of Smart Grid in Malaysia by Universiti Tenaga Nasional (UNITEN). Both projects, funded by United Nations Industrial Development Organization (UNIDO) and Tenaga Nasional Berhad, will change the energy landscape in Malaysia by introducing clean, efficient, and intelligent systems to manage electrical energy usage. Professor Hazlie has actively participated in working groups dedicated to developing industry standards in Malaysia. Two of the standards contributed to High Voltage Switchgear Control Gear & Assemblies (MS IEC 60265-1:2006) and Guidelines for Power System Steady State, Transient Stability, and Reliability Studies (MS 2572:2014) have been widely adopted by industries along with two other standards: Protection Relay Devices (NSC OS/TC 7 /WG 5) and Solar Energy Technologies (NSC 5/TC 8/WG 5) being developed. He represents Malaysia in the standard development activities of the International Electrotechnical Commission (IEC) in TC 8/JWG 10, focusing on system aspects of electrical energy supply.
