Inverter-based distributed generations (IBDGs) are the main approach to utilizing clean energy in distribution networks (DNs). Compared with synchronous source, fault response of IBDG is very different. As a result, in DNs with high penetration of IB

Abstract Considering that no current limiting inductances (CLIs) are installed at the end of the DC line in the flexible DC distribution grid, the protections relying on line boundary are no longer applicable. To overcome this problem, the paper prop

Abstract The total electric field around the DC line is composed of both the ion flow field produced by coronae and the electrostatic field produced by the conductor charge. Under the effect of the total electric field, the disconnected pole will gen

Abstract The emergence of distributed generators has changed the operational mode and fault characteristics of the distribution network, in a way which can severely influence protection. This paper proposes a d-axis-based current differential protect

The flexible DC distribution grid is suitable for distributed energy resource integration and DC load power supply. However, the fast-increasing fault current has a great impact on the system when a short circuit fault occurs. Besides, the existing m

Abstract This paper proposes a novel directional pilot protection method based on the transient energy for bipolar HVDC line. Supposing the positive direction of current is from DC bus to the DC line, in the case of an internal line fault, the transi

Due to the labyrinthine topology of the MMC-MVDC system, identification of the faulty feeder especially for a single-pole-to-ground (SPTG) fault is a challenging task. Based on the characteristics analysis of capacitance charge–discharge, this arti

High-resistance clamping grounding is a common grounding mode of modular multilevel converter (MMC) based DC distribution network. Due to the current limiting function of grounding resistor, pole-to-ground fault can only cause limited steady-state fa
