Compared with the grid-following VSI, the self-synchronizing voltage source inverter (SSVSI) adopts a series of control schemes without PLL operation, such as droop control , , and virtual synchronous generator (VSG) control , , . SSVSI based on VSG control has received a lot of attention in recent years.
Self-synchronizing voltage source inverter (SSVSI) can effectively improve grid frequency stability. However, the synchronous frequency resonance (SFR) inevitably exists in SSVSI. In this paper, a small-signal model considering power coupling is established to analyze the system characteristics.
Plenty of research has been conducted on the self synchronized voltage source control strategy in steady state, but few research is focused on the soft grid integration, which is a complicated process involving wind turbine control and power converter control.
For addressing this issue, this paper proposes a novel control scheme named as power self-synchronization control (PSSC), which enables VSC to operate under grid conditions with short circuit ratio (SCR) from 1 to infinity. Similar to PSC, the proposed method also includes power synchronization loop, voltage control loop, and current control loop.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
Abstract Self-synchronized voltage source inverters (SSVSIs) have attracted much attention for their capability to improve the voltage and frequency stability of power systems.
