چکیده

This paper presents a new circuit topology of a phase-locked loop that can be used for synchronising a singlephase wind turbine generator (WTG) with the low voltage utility grid. The circuit is based on the time-delay digital tanlock loop (TDTL) architecture and was modelled and simulated using Simulink/MATLAB. The results presented demonstrate the ability of the circuit not only to synchronise a WTG with the grid, but also to re-gain synchronization following a sudden disturbance in the grid voltage. The simulated disturbances included a ramp and a multi-step change in the phase of the grid voltage waveform.

Grid Integration of a Single-Source Switched-Capacitor Multilevel Inverter with Boosting Capability

This paper investigates the connection of a single-phase multilevel inverter structure to an existing power grid. The applied voltage source inverter is able to generate a near sinusoidal voltage waveform with an amplitude six times the input voltage by using a single DC input power supply. A proportional-resonant (PR) controller regulates the injected current into the grid. While the EPLL is u...

Low Voltage Ride-Through Capability Improvement of Doubly Fed Induction Generator using DVR and SMES

Abstract: With the growth of communities and the increasing need for electricity, and because of the many benefits of renewable energy sources, the wind turbine has become a completely commercial and inevitable process, with increasing penetration into the electricity grid. Distribution networks, on the other hand, are subject to fault that cause power fluctuations and outflow of wind units. In...

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...

Power Management in a Utility Connected Micro-Grid with Multiple Renewable Energy Sources

As an efficient alternative to fossil fuels, renewable energy sources have attained great attention due to their sustainable, cost-effective, and environmentally friendly characteristic. However, as a deficiency, renewable energy sources have low reliability because of their non-deterministic and stochastic generation pattern. The use of hybrid renewable generation systems along with the storag...
