研究目的
To propose a new approach for grid integration of solar photovoltaic system using modified incremental conductance maximum power point tracking algorithm with multi-output converter and multilevel inverter.
研究成果
The proposed system is able to provide better quality output waveforms with lesser harmonic distortion and offers the advantage of lesser component count. Therefore the system is more suitable for photovoltaic grid connected operation and provides enhanced operation.
研究不足
The proposed grid connected system is examined only in standard test condition. It could be tested with sudden changes at irradiance condition in future work.
1：Experimental Design and Method Selection:
The proposed system utilizes a multi-output boost converter and reduced switch multilevel inverter (MLI) for grid integration of solar photovoltaic system. The multi-output boost converter is a combination of boost converter and switched capacitor function.
2：Sample Selection and Data Sources:
The system is tested with standard test conditions using MATLAB/SIMULINK.
3：List of Experimental Equipment and Materials:
The multi-output boost converter consists of single switch, single inductor, 2N-1 diodes and 2N-1 capacitors. The reduced switch MLI consists of basic units connected in series with a full bridge inverter.
4：Experimental Procedures and Operational Workflow:
The multi-output boost converter switch is operated at 24 kHz. The switches in reduced switch MLI are operated at 5 KHz switching frequency and the switches in full bridge inverter are operated at 50 Hz frequency.
5：Data Analysis Methods:
The performance of the system is analyzed based on the output voltage and current waveform quality and harmonic distortion.
