Abstract
The world is moving at a fast pace towards the renewable energy sources, especially solar power, which is abundantly available all over the world. The solar power can be used for generation of electrical energy either by solar PV or by solar thermal. Generation through solar PV is most promising as it can be used for generation of power as low as few watts to several MWs. But to convert from solar PV to ac, we need an inverter. Multilevel Inverter (MLI) is more recent and popular type of power electronic converter that synthesizes a desired output voltage from several levels of dc voltage as inputs. If sufficient number of dc sources are used, a nearly sinusoidal voltage waveform can be obtained. As compared to hard-switched two-level PWM inverter, multilevel inverter offers several advantages such as, ability to operate at higher voltage with lower dv/dt per switching, high efficiency and low electromagnetic interference etc. Nowadays, newer MLI topologies are emerging with reduced switch and driver count for reduction of switching devices without affecting the performance of inverter and reducing its cost and increasing its efficiency.
The main objective of this project is to develop an interface between solar PV and load, utilising Hybrid Multilevel Inverter (MLI) and P&O MPPT for standalone PV system with Selective Harmonic Elimination (SHE) for efficient and power quality grid code compliant inverter output.
The desire objectives have been achieved by following steps:
- Development of 15-level hybrid multilevel inverter with reduced switch count and control circuit.
- Minimization of harmonic contents in the voltage/current produced by the inverter. The equations representing the different harmonic components will be solved using Selective Harmonic Elimination (SHE) or Optimization Techniques for minimization/ elimination of harmonic components in the output line/ phase voltage/ current.
- Integration of PV array and P & O MPPT with battery to design a rigid DC voltage source.
- Integration and stabilization of developed voltage sources with hybrid MLI circuit.
The simulation results for 15-level multilevel inverters for equal values of DC sources have been verified through experimental results.
