After plotting the active power set point versus irradiance chart, the chart allows the student to analyze the voltage, current and power output for a photovoltaic plant. The project is divided into two parts. Firstly, the student is focused on developing a complete model using MATLAB/Simulink. In details, some irradiance data are introduced into a PV model. The power output from the model is passed through a DC-DC boost converter. Then the power is passed through a DC-AC inverter before being supplied into the grid. For the DC-DC boost converter, a maximum power point tracking (MPPT) algorithm is integrated to extract maximum power at different irradiance levels. The MPPT model has been successfully designed. Secondly, real-time data for 1kW and 2.7kW are verified with the data simulated from Simulink. To obtain the real-time data, National Instrument LABVIEW is implemented to log real-time data. Developing a P/Q capability chart for 1kW and 2.7kW PV plant could also be done using the proposed mothed.

The brief summary of Zhang Qiyu’s Final Year Project is provided in this report. The objective is to develop a model which can produce optimum P corresponding to sets of irradiance data using MATLAB/Simulink software. After plotting the active power set point versus irradiance chart, the chart allows the student to analyze the voltage, current and power output for a photovoltaic plant.
The project is divided into two parts. Firstly, the student is focused on developing a complete model using MATLAB/Simulink. In details, some irradiance data are introduced into a PV model. The power output from the model is passed through a DC-DC boost converter. Then the power is passed through a DC-AC inverter before being supplied into the grid. For the DC-DC boost converter, a maximum power point tracking (MPPT) algorithm is integrated to extract maximum power at different irradiance levels. The MPPT model has been successfully designed.
Secondly, real-time data for 1kW and 2.7kW are verified with the data simulated from Simulink. To obtain the real-time data, National Instrument LABVIEW is implemented to log real-time data. Developing a P/Q capability chart for 1kW and 2.7kW PV plant could also be done using the proposed mothed. Fast and reliable measurement functions such as measurement results presentation and data acquisition are advantages of NI LABVIEW. Simulink detailed model iss successfully verified by comparing Simulink output active power and real-time logged active power.
By developing this project, characterizing a PV plant in terms of P injection into grid is proven to be possible. This P capability chart can help students and engineers to calculate the unit of energy produced. |
