摘要:In many future power systems, the power generation may be predominantly supplied from converter interfaced sources (i.e. wind, solar, HVDC interconnection). In the context of the UK, the government is aiming for a share of wind capacity in the total generation mix as high as 29 G...

摘要:With the development of high-voltage direct current (HVDC), modular multilevel converter (MMC) is seeking its application in onshore wind power integration. AC and DC faults are important issues for the wind power integration system, during which the wind generation system contin...

摘要:The optimum design of power system components is becoming a relevant topic in power system studies. Genetic algorithms (GAs) are considered as a proper approach for optimisation problems in which non-linear elements are involved. Several trends are presently leading GAs to a new ...

摘要:Modular multilevel converters (MMCs) play a critical role in the future energy Internet pattern. Therefore, proper models for the simulation of complex systems with multiple MMCs are required. This study proposes a simplified equivalent model (SEM) based on the implicit trapezoid...

摘要:To date, numerous concepts for converter station designs for use in voltage source converter (VSC)-based high-voltage direct current (HVDC) systems have been proposed. These differ not only in converter circuit topology, sub-module design, and control scheme but also in AC-or-DC ...

摘要:In view of the facts that existing line commutated converter based high voltage direct current (LCC-HVDC) line protection cannot realise satisfactory selectivity, speed, sensitivity, reliability and practicability simultaneously, and that the work of setting calculation for line...
