A Hybrid Simulation Model for VSC HVDC

Nonlinear Control of Back-to-Back VSC-HVDC System via Command-Filter Backstepping

“…The traditional AC and DC transmission technology is still unable to effectively solve the above problems in the technical and economic benefits [2]. With the development of power electronics and control technology, the above problems can be solved by using voltage-source-converter high voltage direct current (VSC-HVDC) composed of IGBT, IGCT, and other new full controlled power electronic devices, which can realize the independent control of active power and reactive power [3]. VSC-HVDC has the following two main advantages, one is that VSC-HVDC transmission technology supplies power to the passive load without the commutation voltage of the AC system, the other one is that VSC-HVDC does not need AC power grid to provide reactive power to stabilize DC voltage, which can work as static synchronous compensator (STATCOM) [2][3][4].…”

Moreover, the other advantages are the following: large transmission capacity, small harmonic of output voltage, low cost and little loss, and the current of the AC-side being controlled so that the short-circuit capacity of the system can not be added [2][3][4][5].…”

Approach to Creating an Information-Control System of Hybrid Power System Simulator

“…Developed according to this approach the concept and tools of adequate simulation in real time of EPS, including smart grids, are considered in [4][5][6]. Hybrid RealTime Power System Simulator (HRTSim) is developed according to this concept.…”

Hybrid Models of Alternative Current Filter for Hvdc

“…The HVDC (high voltage direct current) systems are widely used in electric power system (EPS) with its technical and economic advantages [1,2]. However, operation specific of convertor stations of HVDC is the cause of harmonics which reduce the power quality and disturb the communication system [3,4].…”

“…In this paper the fragments of design of double turned and second-order high pass AC filter models for hybrid model of HVDC, presented in [2,5], are introduced.…”
