چکیده
The Modular multilevel converters (MMCs) have excellent performance when operated with high modulation index such as the case of gird-connected in voltage direct current (HVDC) system. Reliable and fault tolerant operation (FTO) system is very important HVDC. A novel FTO algorithm under sub module failure without using any additional redundant SMs proposed. In proposed method, bus control on-load tap changer (OLTC) strategy are combined for interruption free stress on switching devices degradation during fault. analytical details normal well given. verified through simulation also experimentally a prototype. experimental results presented.

DC Voltage Control and Power-Sharing of Multi-Terminal DC Grids Based on Optimal DC Power Flow and Flexible Voltage Droop Strategy
This paper develops an effective control framework for DC voltage control and power-sharing of multi-terminal DC (MTDC) grids based on an optimal power flow (OPF) procedure and the voltage-droop control. In the proposed approach, an OPF algorithm is executed at the secondary level to find optimal reference of DC voltages and active powers of all voltage-regulating converters. Then, the voltage ...

In this note, we show that the impedance control strategy proposed in the paper is not feasible from practical implementation point of view. Next, a robust impedance controller is proposed for electrically driven robots using Fourier series (FS). The fact that robots' actuators have limited voltage is also considered in controller design procedure. In comparison with other impedance controllers...
متن کاملA DC Voltage Control Strategy for Active Power Filter
Abstract: Active Power Filter (APF) is capable of changing the size and frequency of harmonics as well as changes in reactive power compensation. It is important to control the stability of the DC-link capacitor voltage stability for it. For DC voltage controls of APF, there are two important achievements. First, it is indicated that the control of DC voltage directly affects the compensation p...
