A Cascaded Inverter For Single-Phase Grid-connected Photovoltaic system

Katnal, Ranjita (2013) A Cascaded Inverter For Single-Phase Grid-connected Photovoltaic system. BTech thesis.



The Photo Voltaic (PV) energy system, used in this project, is a very new concept in use, which is gaining immense popularity due to increasing importance to research on alternative sources of energy over depletion of the conventional fossil fuels all around the world. The systems which are being developed extract energy from the sun in the most efficient manner and suit them to the available loads without affecting their performance. In this project, The design and control issues associated with the development of a 1.8 kW prototype single-phase grid-connected photovoltaic system a multilevel cascaded inverter are discussed in this project. For the current controller a ramp time zero average current error control algorithm combined with an optimized cyclic switching sequence is suggested. Simulation results have been presented to demonstrate the suitability of the control method. Simulation results exhibits improved performance under the presence of harmonics and the studied system is modeled and simulated in the MATLAB/Simulink.
