Pumped storage units bring stability to the electrical power system, so they must remain connected to the grid even during grid faults. In this paper, the authors propose efficient and simple solutions for a doubly fed induction machine pumped storage (DFIMPS) system during grid faults. In case of balanced grid faults, a control reconfiguration strategy is introduced and a hardware solution is ...

Grid faults are common in power systems and can have a severe impact on the operation of the converters in the system. In this paper, the operation of a Modular Multilevel Converter (MMC)-based Static Synchronous Compensators (STATCOM) is investigated during grid faults. The study focuses on the challenging internal control of the converter to allow the independent control of the energy levels ...

Rapid renewable energy sources (RESs) deployments in transmission and distribution networks have changed power systems’ operation control mechanisms. This fundamental shift makes the interaction between systems more sensitive requires robust TSO–DSO coordination to ensure system stability ancillary services for entire network. paper uses an electromagnetic transient (EMT) simulation tool using ...

In order to utilize Doubly Fed Induction Generators (DFIGs) as primary power source in an isolated system, they should be able to regulate the voltage and frequency of the system as well as ride-through faults. This paper proposes a new control strategy for a DFIG operating in an isolated power system, accomplished by a Dynamic Voltage Restorer (DVR) and a Supercapacitor Energy Storage System (...

This paper presents a comparative assessment of four low voltage fault ride through (LVFRT) techniques that alleviate the effects power imbalance during AC network faults for source converter (VSC)-based wind energy conversion systems (WECSs). The appraised include software-based coordinated control (CC) technique, commercially available dumping resistor (DR) and two storage techniques, namely,...
