Does a battery-supercapacitor energy storage system work with a VSC?

The efficacy of the proposed control algorithm under the load dynamics, normal source voltages, source voltages’ sag, unbalanced sag, swell, and interruption is verified through the experimental setup of the VSC with the battery–supercapacitor energy storage system. 2. Structure of VSC with battery–supercapacitor energy storage system

How does a VSC operate during a Voltage swell?

During the voltage swell, the VSC operates in the VCM and maintains the load voltages at 1.1 p.u., as shown in Fig. 12 (a) and (c). During this period, the VSC takes the required reactive power from the source. The source and VSC currents are increased due to this reactive power, as shown in Fig. 12 (b).

How does VSC work in CCM?

The source voltage is at 1 p.u. before t 1 and after t 2. The VSC works in CCM during these periods. The load voltage ( v l a) and source current ( i s a) are in phase with each other, as shown in Fig. 10 (b) and (d). The VSC current ( i f i a) includes the reactive and harmonics components of the load current ( i l a ).

How do you calculate VSC power?

This VSC power is calculated as given below: (11) P s h = − 1 T ∫ t 1 − T t 1 ( v l a i f p a + v l b i f p b + v l c i f p c) d t. Since the direction of i f p a, i f p b, and i f p c is from the VSC to the PCC in Fig. 1, a negative sign is used in (11) to indicate the power flow from the source to the VSC.

What is VSC-HVDC power regulation?

In recent years, VSC-HVDC technology has emerged with the strengths of flexible power regulation and strong voltage support. This paper firstly analyzes the VSC-HVDC power transmission characteristics and clarifies the mechanism of the VSC-HVDC power regulation.

Why is a VSC operated in a VCM during a voltage sag and swell?

During the voltage sag and swell, the priority is to regulate the load voltages. Therefore, the VSC is operated in the VCM during the source voltage sag and swell. In the VCM operation, the VSC supplies the required reactive power to the PCC to regulate the load voltage at its reference value.
