Control for Grid-Connected and Intentional Islanding Operations of Distributed Power Generation

TL;DR: An intelligent load-shedding algorithm for intentional islanding and an algorithm of synchronization for grid reconnection to implement grid-connected and intentional-islanding operations of distributed power generation are proposed.
Journal ArticleDOI

A Robust Control Scheme for Grid-Connected Voltage-Source Inverters

TL;DR: This paper analyzes the stability problem of the grid-connected voltage-source inverter (VSI) with LC filters, which demonstrates that the possible grid-impedance variations have a significant influence on the system stability when conventional proportional-integrator (PI) controller is used for grid current control.
Journal ArticleDOI

An Energy-Stored Quasi-Z-Source Inverter for Application to Photovoltaic Power System

TL;DR: Two strategies are proposed with the related design principles to control the new energy-stored qZSI when applied to the PV power system and prove the effectiveness of the proposed control of the inverter's input and output powers and battery power regardless of the charging or discharging situation.
Journal ArticleDOI

A Family of Z-Source Matrix Converters

TL;DR: Simulation and experimental results verify operation of the proposed Z-source matrix converter, analytical results, and control method, and achieve low cost, high efficiency, and reliability, compared to the traditional matrix converters.
Journal ArticleDOI

Current-Fed Quasi-Z-Source Inverter With Voltage Buck–Boost and Regeneration Capability

TL;DR: In this paper, a reverse-blocking insulated-gate bipolar-transistor-based current-fed qZSI prototype was developed in the laboratory, and the available operating regions for motoring and regeneration operation were analyzed.
