Effects of Injection of Solar Photovoltaic Voltage to the Electrical Grid

DC-to-DC boost converter and a DC-to-AC inverter are used extensively by the grid-connected solar PV system which is the subject of interest of this work to deliver quality power to the utility grid. The main parts of the system, includes two solar arrays, a boost converter, and a grid-side three-level inverter. A modified Perturb & Observe (P&O) based relatively new maximum power point tracking (MPPT) method is also employed in this work to observe the performance of proposed grid connected system. At the initial part of this work, the principle and operation of the proposed system has been described briefly and subsequently each part of the elements was investigated separately. A three-level DC to AC inverter of switching frequency 5 kHz is used to regulate the DC-to-DC converter's output voltage and links the PV system to the grid. Proposed Maximum power point tracking (MPPT) based algorithm measures the maximum power of a PV cell. The simulation results show that the variations in solar radiation may affect the performance of PV systems as well as the performance and dynamic behavior of grid-connected photovoltaic systems.
