“…The inner loop controller controls the current in the AC side of the VSC [16]. The outer loop feeds the current references to the inner loop in order to maintain an adequate voltage reference for the VSC; it includes the DC voltage regulator, the AC voltage regulator and the active and reactive power regulators [17]. However, all these regulators cannot be used in the same time, the choice of the controller depends on the application mode of the VSC-HVDC system.…”

The use of high voltage direct current based voltage source converter (VSC-HVDC) in power transmission systems knows a great progress in recent years. Above all, with the new generation of power electronics converters such as the modular multi-level converter (MMC), with his scalable structure it can theoretically meet any voltage level requirement, which allows to increase the size of the power transferred compared to conventional converters. In this sense, this paper presents a study of a VSC-HVDC system based on a modular multi-level converter (MMC). The main objective of this work is to analyze the performance of the VSC-HVDC system based MMC without the AC filters and its control in the event of a fault, during set point changes and unbalanced grid conditions. After realization a mathematical model of the system studied and its control, simulations are done over in Simpower System/Matlab. The results obtained confirm the robustness of the system control and the system gives a good energy quality, that manifests by a good output currant and voltage curves with no need to use a voluminous AC filter.

“…In addition, this structure is robust to a poleto-ground fault, which does not cause steady-state fault currents for the test system [20]. The pi section model is widely used in the literature to simulate the HVDC cables for transient studies [21][22][23][24][25][26][27]. To obtain satisfactory simulation accuracy, each cable is modeled with 10 pi sections in this paper to simulate high frequency behavior during a fault [22,28].…”

Abstract-VSC based Multi-terminal HVDC transmission is employed for the integration of offshore wind and wave farms. Flexibility, reliability and reduced transmission losses are the main/primary reasons for preference of MTDC networks. The transmission layout still suffers from some drawbacks, of which the most prominent is fault ride through capability in terms of its response to either a temporal or permanent loss of converter station(s). This paper presents the simulation analysis of hysteresis based and PI-based DC grid voltage control techniques for fault ride through capability of a 4 terminal HVDC network (MTDC), which consisted of a wind farm, wave farm and two onshore converters. The analysis showed that the PI method resulted in a faster response time as well as smaller overshoots and dips when a three phase to ground fault occurs. A detailed electromagnetic transient (EMT) study was performed using MATLAB/Simulink. Index Terms--Fault ride through (FRT), Hysteresis controller, PI controller, VSC HVDC, MTDC.
