Mppt with single dc–dc converter and inverter for grid connected hybrid wind-driven pmsg–pv system
1 like87 views
This document describes a new hybrid distributed generator system that uses a photovoltaic array and permanent magnet synchronous generator driven by wind to generate power. The system uses a single boost converter and inverter to connect the sources to the grid, requiring fewer power converters than previous schemes. MATLAB/Simulink is used to model and simulate the system. Low-cost controllers are proposed for the boost converter and inverter to independently track the maximum power from each source. Simulation and experimental results demonstrate the successful operation and performance of the new hybrid system.

CONCLUSION:
A new reliable hybrid DG system based on PV and wind driven PMSG as sources, with only a
boost converter followed by an inverter stage, has been successfully implemented. The
mathematical model developed for the proposed DG scheme has been used to study the system
performance in MATLAB. The investigations carried out in a laboratory prototype for different
irradiations and PMSG shaft speeds amply confirm the utility of the proposed hybrid generator in
zero-net-energy buildings. In addition, it has been established through experimentation and
simulation that the two controllers, digital MPPT controller and hysteresis current controller,
which are designed specifically for the proposed system, have exactly tracked the maximum
powers from both sources. Maintenance-free operation, reliability, and low cost are the features
required for the DG employed in secondary distribution systems. It is for this reason that the
developed controllers employ very low cost microcontrollers and analog circuitry. Furthermore,
the results of the experimental investigations are found to be matching closely with the
simulation results, thereby validating the developed model. The steady state waveforms captured
at the grid side show that the power generated by the DG system is fed to the grid at unity power
factor. The voltage THD and the current THD of the generator meet the required power quality
norms recommended by IEEE. The proposed scheme easily finds application for erection at
domestic consumer sites in a smart grid scenario.

In this generator, the sources are connected together to the grid with the help of only a single boost converter followed by an inverter. Thus, compared to earlier schemes, the proposed scheme has fewer power converters. A model of the proposed scheme in the d − q-axis reference frame is developed. Two low-cost controllers are also proposed for the new hybrid scheme to separately trigger the dc–dc converter and the inverter for tracking the maximum power from both sources. The integrated operations of both proposed controllers for different conditions are demonstrated through simulation and experimentation. The steady-state performance of the system and the transient response of the controllers are also presented to demonstrate the successful operation of the new hybrid system. Comparisons of experimental and simulation results are given to validate the simulation model. KEYWORDS: 1. Grid-connected hybrid system 2. Hybrid distributed generators (DGs) 3. Smart grid 4.
