Most of inverters in the grid are based on constant current control where inner current control loop tries to limit the current. Hence acting as a constant current source. I was wondering how control philosophy will be difference if we were to model the same inverter as a constant voltage source?
The output F/V characteristics of the inverter, that is, the load torque output mode, are basically divided into two types: a constant relationship (corresponding to constant torque mode) and an exponential relationship (corresponding to the fan-type load mode), not divided into constant power and constant torque.
At higher real power production the inverter produces (or absorbs) higher reactive power, with the converse at lower real power production. The power factor setting of many smart inverters is adjustable from + 0.8 to 1.0. According to IEEE 1547-2018, constant power factor mode with 1.0 power factor is the default reactive power control mode.
Most of the inverters on the grid are based on energy storage in an inductance, either in a discrete inductor, or the inductance of a transformer. The purpose of the outer loop is to control the flow of power to the load. The purpose of the inner loop is to control the cycle by cycle energy contained in the energy storage element.
