Abstract: This project is to implement an alternative topology for a series-series grid connected power system. The existing system uses traditional voltage-source inverters (VSIs) and these inverters have a limited operating range. To overcome the limited operating range, these inverters need to be connected with a separate dc-dc converter stage to enable them to operate in both buck and boost modes. [6] This topology commonly known as two-stage inverters is used in the existing system. An alternative topology for a series-connected photovoltaic system that is able to overcome the various limitations of VSIs and provide single stage voltage boosting capability is proposed with the use of Z-source inverters. In this Final Year Project, the focus is on design of the proposed series connected solar photovoltaic system using Z-source inverter (ZSI) topology. The focus of the project will be on the simulation of the proposed system and it is will be on the design of the PV-circuit, MPPT model, Z-source impedance network, PWM control strategy and filter design in the first part of the report. Subsequently, the AC/DC control of the Z-source series connected PV system will be implemented in the later part of the report. All of the simulations are conducted using MATLAB/Simulink.
