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 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.
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 VCM?
The VSC current ( i f i a) includes the reactive and harmonics components of the load current ( i l a ). The battery current is zero as it is fully charged. A source voltage sag of 20% is created at t 1 and removed at t 2. The VSC works in VCM during this period. The load voltage is maintained at 0.9 p.u., as shown in Fig. 10 (a) and (c).
How many energy storage de- vices are used in the WSCC 9-bus test system?
Three energy storage de- vices are considered, namely, SMES, CAES and BES. With this aim, the WSCC 9-bus test system (see Fig. 11) is used for all simulations. This benchmark network consists of three synchronous machines, three transformers, six transmission lines and three loads.
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.
