This paper deals with the implementation of open loop control method for the grid connected inverter. 120-degree mode of inverter control is used in paper for simulation. The control method gives less THD in inverter output current and the inverter output current is in phase with grid voltage so it gives unity power factor operation. 1.
Configuration is carried out under Cluster Controller > Grid management services > Active power. In order for the inverters to be able to receive output values from the Cluster Controller in the course of closed-loop control, you must configure the inverters appropriately.
This control is based on the single phase inverter controlled by bipolar PWM Switching and lineal current control. The electrical scheme of the system is presented. The approach is widely explained. Simulations results of output voltage and current validate the impact of this method to determinate the appropriate control of the system.
Note that with a 0-watt closed-loop control in the PV system, there is always a base load (self-consumption) of approx. 25 W x number of inverters in the PV system. This results in minor control deviations.
