Smart grid operations and control challenge by implementing SSSC tailored to optimize performance in between United Arab Emirates and Oman on the GCC power grid
This research work is novel technique to control and optimize SSSC operations with degree of precision in between United Arab Emirates and Oman. The SSSC model developed and simulated in order to identify and determine its control and opera...
Strategy of AC-isolated island detecting and control mode switching over in Zhoushan Project
One of the greatest challenges faced by Zhoushan Project is that AC-isolated island can easily be formed due to the weakness of the AC grid connected to the VSC system and vulnerability to typhoon attack. A strategy based on frequency varia...
Real time control of a distribution connected MVDC link (ANGLE-DC)
This paper investigates the real-time control of a Point to Point DC link. The DC link will be used to simultaneously control both power flow and voltage within a constrained distribution network. The operational envelope, overall control s...
Initial designs for the ANGLE DC project; converting existing AC cable and overhead line into DC operation
ANGLE DC is an innovative project which will convert two existing AC distribution circuits from the island of Anglesey to the Welsh mainland to operate as DC circuits. At present, there is a double circuit 33kV AC connection between the Lla...
The importance of engineers in successful consenting for project developers
National Grid Interconnector Holdings (NGIH) develops HVDC interconnector projects and in recent years has been responsible for developing Nemo Link [1], North Sea Link (NSL) [2], IFA2 [3] and Viking Link [4]. Through our experiences we hav...
Study and application on the starting test technology for series transformer of UPFC project
Due to the special topology and interconnection mode to the power network, the start-up testing method for conventional transformer will be not fit to series transformer in UPFC project. For the construction of a practical UPFC project, a f...
A calculation method for maximum steady-state loss of VSC-HVDC grounding resistor in Luxi back-back HVDC interconnector
A back-back HVDC interconnector project is under construction at Luxi, Yunnan Province, China. One of two HVDC links of the project is rated 1000 MW using VSC-HVDC technology. The secondary side of converter transformer of VSC-HVDC is groun...
Research on flexible graphite-copper composited electrical grounding material
The metallic grounding material such as copper, steel and alloys plating used in power system nowadays are facing lots of problems such as corrosion, high maintenance cost and so on. To solve these problems, a new type of grounding material...
Optimal redundancy configuration method of wave-shaping circuits and director switches in hybrid multi-level converters
Alternate arm converter (AAC) and hybrid cascaded multilevel converter (HCMC) are two promising hybrid multi-level converters (HMCs) for long-distance overhead line (OHL) based high voltage direct current (HVDC) transmission systems. This p...
Stablity of a modular multilevel converter based HVDC system considering DC side connection
This paper conducts a detailed analysis on the dc side interaction of a modular multilevel converter based HVDC system. The dc side is modelled as a cable system with a voltage controlled remote converter. To implement such research, detail...
