Phase locked loop and synchronization methods for grid - interfaced converters : a review

Phase locked loop and synchronization techniques are one of the most important issues for operating grid-interfaced converters in practical applications, which involve Distributed Power Generation Systems, Flexible AC Transmission Systems (FACTS), and High Voltage Direct Current (HVDC) Transmission, and so on. This paper presents a comprehensive review of the recently developed phase locked loo...

Software Phase Locked Loop Design Using C2000TM Microcontrollers for Single Phase Grid Connected Inverter

Grid connected applications require an accurate estimate of the grid angle to feed power synchronously to the grid. This is achieved using a software phase locked loop (PLL). This application report discusses different challenges in the design of software phase locked loops and presents a methodology to design phase locked loops using C2000 controllers for single phase grid connection applicati...

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 ...
