Improvement of Low Voltage Ride – through Capability of Distributed Generation in a Microgrid Using Superconducting Fault Current Limiter
Although the introduction of distributed generation (DG) in a distribution system improves the power quality of power system, it increases the fault current level reducing voltage at point of common-coupling (PCC). Hence, there is a need of improving fault ride-through (FRT) capability to avoid sudden tripping of DG units from the utility grid during voltage sag in a faulty condition. In this p...
متن کاملA New Method to Enhance the Low Voltage Ride Through Capability of Doubly Fed Induction Generator Using Resistive Type Superconducting Fault Current Limiter
In the event of voltage sag at the nearing of a wind park, severe currents may pass through the power electronic devices of the Doubly Fed Induction Generators (DFIGs). Hence, according to the Low Voltage Ride Through (LVRT) requirements, the wind parks are allowed to disconnect from the network after a certain time. Therefore, to avoid such actions, the LVRT requirement of wind parks is consid...

This paper presents modeling of an Alternating Current (AC) Photovoltaic (PV) module using Matlab/Simulink. The proposed AC-PV module model is simple, realistic, and application oriented. The model is derived on module level as compared to cell level directly from the information provided by the manufacturer data sheet. DC-PV module, MPPT control, BC, VSI and LC filter, all were treated as a si...
متن کاملLow Voltage Ride Through Enhancement Based on Improved Direct Power Control of DFIG under Unbalanced and Harmonically Distorted Grid Voltage
In the conventional structure of the wind turbines along with the doubly-fed induction generator (DFIG), the stator is directly connected to the power grid. Therefore, voltage changes in the grid result in severe transient conditions in the stator and rotor. In cases where the changes are severe, the generator will be disconnected from the grid and consequently the grid stability will be attenu...
متن کاملRegulation of Current/Voltage Characteristics in Photovoltaic Pumping Systems
A PV pumping system using induction machine is thoroughly investigated in this work. The power structure is constituted of multiple parallel DC/DC step-up converters directly connected to the inverter. Each DC/DC converter is used as a DC current transformer. The input characteristic of the inverter is enforced by means of an appropriate regulation, in order to avoid problematic dynamic resista...
