Modeling and Analysis of Grid-Connected Inverter for PV Generation

Abstract

In order to improve the efficiency of photovoltaic generation as well as the power quality, grid-connected inverters for PV generation research was carried out for photovoltaic maximum power point tracking. Based on some current studies on the incremental conductance method, an advanced incremental conductance control algorithm was proposed, which can track maximum power point rapidly and accurately. The oscillation phenomenon, which exists near the maximum power point, was improved at a great extent, so to the efficiency of photovoltaic cells generation electricity. The inverter control system has an advantage in its high speed and flexibility by applying advanced control algorithm. And the source harmonic current is remarkably reduced. In addition, the power factor is enhanced and the power quality is improved. Finally, according to the principle of inverter control system and based on the analysis on the mathematical model of photovoltaic inverter, a simulation model of that is established based on MATLAB/SIMULINK.

Optimization of Renewable Energy-Based Smart Micro-Grid System

“…In this micro-grid model, generator gives the reference signal in the micro-grid and manages the voltage and frequency using the diesel engine governor [30]. Diesel generator converts fuel energy (diesel or bio-diesel) into mechanical energy via an internal combustion engine, and next into electric energy by way of an Figure 13 presents model of diesel engine and output power curve in MATLAB/SIMULINK [26].…”

Design and Control of A Single-Phase Grid-Connected Inverter

“…An analytical approach is also examined in this of type inverter structure to provide the stability of the system [7]. Modeling, analysis, and design studies of grid-connected inverter structures are also investigated in PV integrated applications [8][9][10]. A grid-connected inverter structure is also evaluated in microgrid applications [11].…”
