Efficiency assessment of technologies implementation in Vietnam power transmission system

Many flaws have emerged on Vietnam power transmission system, such as obsolete technology and aging components. High voltage direct current (HVDC) system, 750 kV system, Aluminum Conductor Composite Core (ACCC) conductor are determined by Vietnam government to be implemented because of their performance as well as their suitability to the existing system. Newton Raphson load flow method is utilized to analyze different scenarios, in which performance of these technologies are compared with each other to identify the most robust method to decrease real power loss in steady state working condition. As results signified, 750 kV system is the solution with highest efficiency, whereas ACCC and HVDC’s performance does not match the expectation.
