  Inspired by the kinetics of wave phenomena in reaction-diffusion models of
biological systems, we propose a novel grid-forming control strategy for
control of three-phase DC/AC converters in power systems. The
($\lambda-\omega$) virtual oscillator control or (lambda-omega) VOC is a
natural increment on ideas from virtual oscillator dynamics rotating at a fixed
nominal frequency to adaptive, angle-based frequency function. We study a
network of identical three-phase DC/AC converters interconnected via $\Pi$
transmission lines. For this, we prove almost global asymptotic stability for a
reduced (time-scale separated) version of the model, associated to a
well-defined set of controller gains and system parameters. Additionally, we
link the (\lambda-\omega) VOC to well-studied controllers in the literature,
e.g. droop control. Finally, we validate our results on an example three DC/AC
converter network.
