Renewable Power Systems and in particular Grid-Connected PV Inverter Should not be limited injecting the active power into the grid. However, it must be able to absorb or to generate sufficient reactive power for a certain amount of time according to the grid demand in order to maintain the grid voltage. This paper aims to design a system that controls the active and the reactive power for a Single-Phase...
Now a days due to recent advances in Photovoltaic (PV) panels, the demand on solar energy is increasing. In order to commercialize & utilize solar energy properly we have connect it the grid. This paper deals with the design & simulation of two stage converter system for integrating PV panel with the grid. It consists of PV panel, boost dc- dc converter for stepping up the PV panel voltage,...
The proposed experimental system uses TMS320F28027 as the control core to realize the functions of maximum power point tracking (MPPT), synchronizing of the output voltage with the given frequency and phase, under voltage and over current protection, under voltage recovery and others. The topology of the main circuit is a full bridge inverter controlled by the unipolar sinusoidal pulse-width-modulation...
This paper presents a single-phase 11-level (5 H-bridges) cascade multilevel DC-AC grid-tied inverter. Each inverter bridge is connected to a 200 W solar panel. OPAL-RT lab was used as the hardware in the loop (HIL) real-time control system platform where a Maximum Power Point Tracking (MPPT) algorithm was implemented based on the inverter output power to assure optimal operation of the inverter when...
