How a parallel PV/BSS is integrated with the grid?
Parallel PV/BSSs are integrated with the grid using a VSG control. The VSG control is utilizing an ADC for the system frequency regulation. GA optimization is used to find the optimized values for VSG control parameters. Three different case studies including an IEEE 14 bus system is utilized.
What is the reference frequency of vsg-1 and VSG-2?
The reference frequency of both VSG-1 and VSG-2 remains at 314.156 Hz/s (f = 50 Hz) where, both VSGs follow an equivalent droop control of multi-VSG system sourced by two VSGs. An advanced droop control of VSG is compared with simple VSG control shown in Table 1 , , . Table 1. Comparison of simple VSG control and proposed VSG control.
Do parallel converter-based VSGs have active and reactive power?
Output active and reactive powers of parallel converter-based VSGs with and without the virtual resistance at Rline / Xline = 1/8. The subject of this paper is dedicated to the control of parallel-operated converter-based VSGs in low-voltage grids with dominant resistive line impedances.
How can a VSG reduce power oscillation?
A relatively large virtual inertia in a VSG may result in power oscillation, and consequently in [ 29] a control scheme is suggested to mitigate the power oscillation by adjusting virtual synchronous reactance, damping and load frequency coefficients.
What is VSG power system?
The VSG system comprised of power electronics components having a droop control mechanism like the conventional synchronous generator, which provides the necessary frequency stability to the power system.
Does secondary frequency control work for multiple VSGs in parallel?
That is, after the completion of secondary frequency control, each VSG assumes a load power of 25 kW, and the output of the three VSGs is consistent. The effectiveness of the improved secondary frequency control strategy for multiple VSGs in parallel is verified.
