PO MPPT for wind energy system with grid in MATLAB
We delve into the intricacies of grid-integrated wind energy conversion systems in ML (Machine Learning). In this simulation model, we explore the components and control mechanisms involved in harnessing wind energy and integrating it into the electrical grid.
Components of the System:
The grid-integrated wind energy conversion system comprises several key components:
Wind Turbine with a 3 kW rating.
Permanent Magnet Synchronous Generator (PMSG).
Boost Converter controlled by Perturb and Observe (P&O) method.
Diesel Link, including an inverter for grid connection.
Inverter with a single-phase inverter connected to the grid via a LCL filter.
Control Logic, incorporating voltage and current controllers, as well as a feedforward decoupling control concept.
Power Measurement Devices, monitoring rectifier voltage and current for control purposes.
Operation and Control:
The wind turbine generates power, which is converted to DC by the PMSG and diode rectifier.
The Boost Converter regulates the DC voltage based on P&O method and feeds it to the diesel link.
The inverter converts DC to AC and injects it into the grid after appropriate control actions.
Control logic involves voltage and current control loops, ensuring efficient power transfer and grid synchronization.
Feedforward decoupling control optimizes power injection into the grid based on measured variables.
Simulations and Results:
The simulation involves varying wind speeds to observe system response.
Scopes display voltage, power, and current waveforms at different points in the system.
Power quality is assessed through Total Harmonic Distortion (THD) analysis, indicating compliance with standards.
Conclusion:
Grid-integrated wind energy conversion systems play a crucial role in renewable energy generation and grid stability. Through sophisticated control mechanisms and careful design, these systems enable efficient utilization of wind energy resources while maintaining power quality standards. Continued research and development in this field are essential for achieving a sustainable energy future.
