متن کاملA New Control Method for Single-Phase Grid-Connected Inverter Using Instantaneous Power Theory
Because of installation for local consumers and since it is free of all contaminations, connecting photovoltaic cells to the grid via single-phase inverter is significantly on the rise. In this paper, a new simple current control is proposed for a single-phase grid-connected voltage source inverter. Using the PQ theory and modelling a single-phase system as an unbalanced three-phase system, a m...
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 کاملFuzzy Based Improvement of Power Quality in 1-Φ Grid-Connected PWM Voltage Source Inverter
The Distributed generated system originated due to the demand of electrical energy and keen scarcity of conventional energy sources. The main problem is the harmonization of the DG to the utility grid. Usually, for synchronizing the utility grid with DG source current regulated PWM voltage-source inverters (VSI) are used in order to meet the following objectives: 1) To improve grid stability 2)...
