Distributed Power System Virtual Inertia Implemented by Grid-Connected Power Converters

A Novel Control Strategy for a Single-phase Grid-connected Power Injection System

In this paper, a novel and simple control strategy, based on state feedback method is suggested to control the power injection system (PIS). The considered PIS is composed of, a DC voltage source, a voltage source inverter (VSI) and a L-C-L filter. The DC source includes the battery source with boosted voltage. The battery can be charged with photovoltaic cells. Since, the grid voltage acts as ...

Power Conversion System for Grid Connected Micro Hydro Power System with Maximum Power Point Tracking

Optimal Operation of Doubly-fed Induction Generator used in a Grid-Connected Wind Power System

In this paper, a wind power system based on a doubly-fed induction generator (DFIG) is modeled and simulated. To guarantee high-performance control of the powers injected into the grid by the wind turbine, five intelligent super-twisting sliding mode controllers (STSMC) are used to eliminate the active power and current ripples of the DFIG. The STSMC controller is a high-order sliding mode cont...

Active Power Control of Grid-Connected Distributed Generation Unit

The growth in energy consumption and awareness on global warming has increased the focus on Distributed Generation (DG) using non-conventional energy sources. The stand-alone DGs are used to mitigate the challenge of rural electrification and the grid connected DGs are used to reduce demand on power system network. The DG in grid connected mode operates in parallel with main grid and supplies a...

Power Converters for Grid Integration of Wind Power Systems

This paper presents the different power converters for grid integration of wind power systems. In wind power systems while integrating with grid, power quality issues are becoming more predominant. This can solve by using power electronics converters like two level back to back converter and matrix converters. Converters are compared on the basis of efficiencies, voltage conversion ratios and T...
