What is the control design of a grid connected inverter?
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.
How is an inverter connected to a grid?
The inverter is interfaced to the grid via an LCL filter. A relay is used to connect and disconnect the inverter from the grid whenever required by the application. The schematic in Figure 11 shows the filtering and relay schematic section.
How to synchronize grid-connected inverters with grid current?
Initially, the proposed control of the grid side is introduced. Secondly, to synchronize the grid side voltage with grid current, a synchronous reference frame (SRF) based phase locked loop (PLL) is applied. Finally, the simulation of grid-connected inverters using PSIM is presented to illustrate concepts and results.
Can a grid connected inverter be left unattended?
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. The control design of this type of inverter may be challenging as several algorithms are required to run the inverter.
What is a grid-connected inverter?
4. Grid-connected inverter control techniques Although the main function of the grid-connected inverter (GCI) in a PV system is to ensure an efficient DC-AC energy conversion, it must also allow other functions useful to limit the effects of the unpredictable and stochastic nature of the PV source.
Can grid-connected PV inverters improve utility grid stability?
Grid-connected PV inverters have traditionally been thought as active power sources with an emphasis on maximizing power extraction from the PV modules. While maximizing power transfer remains a top priority, utility grid stability is now widely acknowledged to benefit from several auxiliary services that grid-connected PV inverters may offer.
