500kw grid-connected photovoltaic inverter reference
This paper aims to select the optimum inverter size for large-scale PV power plants grid-connected based on the optimum combination between PV array and inverter, among several
The control design of this type of inverter may be challenging as several algorithms are required to run the inverter. This reference design uses the C2000 microcontroller (MCU) family of devices to implement control of a grid connected inverter with output current control.
The user must not touch the board at any point during operation or immediately after operating, as high temperatures may be present. Do not leave the design powered when unattended. Grid connected inverters (GCI) are commonly used in applications such as photovoltaic inverters to generate a regulated AC current to feed into the grid.
GRID-CONNECTED POWER SYSTEMS SYSTEM DESIGN GUIDELINES Assume that the minimum voltage window for an inverter is 140V. Recommended that a safety margin of 10% is used. Minimum inverter voltage of 1.1 x 140V = 154V should be used. The minimum number of modules in a string is = 154 / 26.6 = 5.79 rounded up to 6 modules
