Speaker: Musse Mohamud Ahmed

Musse Mohamud Ahmed joined the Department of Electrical & Electronics Engineering (EEE), Faculty of Engineering, Universiti Malaysia Sarawak (UNIMAS), in July 2016 as a Professor. He currently serves as a consultant for senior power engineer for the World Bank project related to AC Extra High Voltage Transmission Interconnections. With a Ph.D. from Universiti Teknologi Malaysia (UTM) in 2000, he held the several positions in some of Institutions of Higher learning (IHL) such as, MMU as a Lecturer (200-2002); KUTM/UTeM Melaka as Lecturer, Senior Lecturer, and as Associate Professor and as Deputy of Postgraduate and Research & Development at the Faculty of Electrical Engineering (2002-2009); and an Associate Professor at the Kulliyyah of Engineering, International Islamic University Malaysia (IIUM) from 2009 to 2016. He is an IEEE senior member with 39 years of industry and teaching experience. His expertise encompasses Smart Grid Technology, Digital Substations, Large Power System Operation and Control, and Renewable Energy, Energy Management, IOT based applications to power and energy areas among others. He has authored 100+ articles and proceedings, along with books on Distribution Automation, Energy Efficiency, and Solar Energy Applications. He supervised over 30 postgraduate students, managed National and International research projects, and has been a prominent figure in IEEE-PES Malaysia for 22 years. He conducted many Electrical Engineering and Energy Courses for professional engineers in diverse geographical locations.

Title: DC Green Grid as Green Energy Production


Power Transmission lines are either designed in AC or DC according to the requirement by the specific requirement, or infrastructure owner preference such as national grid system owner or state level grid system owner. In Malaysia all the transmission line systems are in AC systems while tie lines connected to either Thailand or Singapore are DC tie lines as interconnection lines. This tutorial proposes a new DC line system that could be used to supply DC sources based renewable energy as green energy transmission line carrier.  to take care of all the newly quantified renewable energy sources in in Malaysia and elsewhere in the world as alternative transmission to the already existing AC transmission line systems.

Why Green Grid is Necessary?

The reason why this new DC transmission line system is proposed is summarized as:

  1. To get an alternative DC transmission line system that may tackle future Green Energy Grid for urbanization mega project such as LRT/MRT, Monorails, transportation, hydrogen infrastructure that solely uses DC system.
  2. Electric Vehicle Station (EVS) which uses DC storage system.
  3. To provide DC system to the existing distributed renewable energy so that they can inject to their DC consumers located in remote areas in Malaysia specially in Sarawak State and Sabah States.

The Main Contents of the Tutorial

  1. Introduction
  2. Why Green Grid is needed.
  3. Comparison between DC and AC after AC-DC Conversion during DC based infrastructure projects.
  4. Where to go from here
  5. Points to nurture
  6. Q&A
