Resonant Characteristics Analysis and Suppression Strategy of Multiple Parallel Grid-connected Inverters with LCL Filter
The multiple parallel inverters have more than one resonant frequency influenced by many factors, which tends to result in stability and power quality problems. This paper develops the multiple input multiple output model of the grid-connected inverters system using the closed-loop transfer function. The influence factors of resonant characteristics are analyzed with the developed model. The an...
متن کاملLoad Sharing Control of Parallel Inverters with Uncertainty in the Output Filter Impedances for Islanding Operation of AC Micro-Grid
Parallel connection of inverter modules is a solution to increase reliability, efficiency and redundancy of inverters in Micro-Grid system. Proper load sharing among parallel inverters is a key point. The circulating current among the inverters can greatly reduce the efficiency or even cause instability of the system. In this paper, a control strategy for improving the load sharing performance ...
متن کاملPower control flexibilities for grid-connected multi-functional photovoltaic inverters
This study explores the integration issues of next-generation high-penetration photovoltaic (PV) systems, where the grid is becoming more decentralised and vulnerable. In that case, the PV systems are expected to be more controllable with higher efficiency and reliability. Provision of ancillary and intelligent services, such as fault ride-through and reactive power compensation, is the key to ...
متن کاملModeling and Analysis of Resonance in LCL-Type Grid-Connected Inverters under Different Control Schemes
As a basic building block in power systems, the three-phase voltage-source inverter (VSI) connects the distributed energy to the grid. For the inductor-capacitor-inductor (LCL)-filter three-phase VSI, according to different current sampling position and different reference frame, there mainly exist four control schemes. Different control schemes present different impedance characteristics in th...
