Coordinated Control Strategy of DC Fault Ride-through for the WF Connected to the Grid Through the MMC-HVDC

Control System Design and Fault-Ride-through Performance Analysis of Grid-Connected Microturbine Generation System

In recent years, microturbines as one the distributed generation sources have widly used. This paper investigates the control structure of the microturbine and analyzes its performance in grid-connected mode. In this way, first, the mechanical model of the microturbine is presented. Then, the electrical structure of the microturbine, consisting  of permanent magnet synchronous generator (PMSG) ...

Fault Ride Through Effects on Alternators Connected to the Grid

Traditionally, industrial countries have generated most of their electricity in large centralised facilities, such as fossil fuel (coal, gas), nuclear, large solar power plants or hydropower plants. Although these plants have excellent economies of scale, they usually transmit electricity over long distances and negatively affect the environment. More recently, a surge in the concerns over clim...

Intelligent Controller Based Improved Fault Ride-through Capability of Hvdc System Connected to Weak Ac Grid

In the paper, a novel HVDC transmission system operating with weak ac system has been modeled with speed and precision & analyses the control strategy & performance of system, which is controlled using fuzzy. The system can feed a weak or even dead network under fluctuations and big variations of the input power. The fuzzy logic-based control of the system helps to optimize the efficiency of th...

Efficient low-voltage ride-through nonlinear backstepping control strategy for PMSG-based wind turbine during the grid faults

This paper presents a new nonlinear backstepping controller for a direct-driven permanent magnet synchronous generator-based wind turbine, which is connected to the power system via back-to-back converters. The proposed controller deals with maximum power point tracking (MPPT) in normal condition and enhances the low-voltage ride-through (LVRT) capability in fault conditions. In this method, to...
