This project models and simulates a 5 MW grid-connected photovoltaic (PV) system using a 3-phase voltage-source inverter (VSI) in MATLAB/Simulink. It demonstrates PV power generation, MPPT control, inverter operation, and grid synchronization under variable irradiance.

A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The resulting AC frequency obtained depends on the particular device employed.

The inverter outputs three phase AC current to a step-up transformer. The step-up transformer outputs to a collector in the substation component, in which flows to the collector arrangement, feeder arrangement and key protection component.

Most quality inverters operate at 85-95% efficiency, meaning 5-15% of input power is lost as heat during AC-to-DC conversion. For example, charging a 100Ah battery at 12V requires approximately 1.
