Generally, inverters do not require a voltage stabilizer as they have some voltage regulation capabilities. However, in certain situations, such as in areas with poor grid quality or for devices requiring high-precision power supply like electric vehicles, using a voltage stabilizer can better ensure stable operation of electrical devices.
Although the inverters’ set-points are 3 kW and 1 kW, respectively, they supply power after deviating from their nominal power set-points because of the application of droop control with line resistance. In a resistive network, the active power flow depends on its own voltage and difference in voltage between the two points shown in Fig. 9.
During network contingencies, this voltage increases and exceeds the safe limit which causes the protection scheme to shut down the inverter. As this phenomenon decreases a system's reliability, a regulator is designed to control the dc-link voltage during a voltage limit violation and thereby protecting the inverter from shutting down.
Inverter is a convenient power converter that can convert DC power into AC power which is the same as the mains power for general electrical appliances. An inverter must be a component of an inverter device. It is directly different from a transformer. In other words, it can realize DC input and then output AC.
Inverter is to convert direct current (DC) to alternating current (AC), to provide a stable power supply for electrical equipment. It is mainly composed of two parts: oscillation circuit and step-up transformer. ● Voltage conversion: Converts low-voltage DC to high-voltage AC.
From Eq. (15), it can be concluded that, as the active power of the inverter depends on its own terminal voltage, even if the voltage difference between terminal voltages equals zero, it will still flow. Eq. (16) reveals that the reactive power depends basically on the power angle difference and does not flow if this difference is zero.
