Title:

Enabling gid-forming control in unbalanced distribution networks.

Abstract:

Distribution networks are often unbalanced, causing oscillatory responses in inverter control designed for balanced conditions. To address this problem, this paper develops a grid-forming control effective under unbalanced conditions and meets specifications by setting and regulating frequency and voltage, providing voltage support, sharing active power, injecting negative sequence current, and providing fault ride-through. The proposed control features enhanced frequency and voltage droop controllers and nested current and voltage control loops that all nicely integrate an enhanced current limiter. To achieve the control design, a time-domain transformation appropriate for inverter control is proposed. This enables time-domain decomposition of unbalanced electrical signals into positive and negative synchronous reference frames. The effectiveness of the proposed transformation and grid-forming control is demonstrated through real-time simulation of a modified IEEE 123 distribution network on the Real-Time Digital Simulator.
