Abstract: Large solar photovoltaic (PV) penetration using inverters in low-voltage (LV) distribution networks may pose several challenges, such as reverse power flow and voltage rise situations. These challenges will eventually force grid operators to carry out grid reinforcement to ensure continued safe and reliable operations.
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 voltage level of the low-voltage grid connection system accessing the power grid is usually 380V (three-phase) or 220V (single-phase), which is exactly the common voltage in our daily electricity consumption.
The high-voltage grid-connected inverter has a high-voltage output capacity. The AC grid-connected voltage levels of 1100V DC high-voltage inverters are generally 480Vac, 500Vac, 540Vac, etc., and the AC grid-connected voltage level of 1500V DC high-voltage inverters is 800Vac.
