Control Strategy Design and Parameter Selection for Suppressing Circulating Current Among SSTs in Parallel
TL;DR: The “matching concept” regarding the parameter selection of virtual and external inductance is proposed to ensure the reliable operation of the system through constructing the complete small-signal model of SST and the adaptive virtual impedance control strategy is proposed by introducing the feedback of circulating current into the conventionalvirtual impedance control.

Seamless Mode Transition Technique for Virtual Synchronous Generators and Method Thereof
TL;DR: This article deals with a method for seamless transition of three-phase virtual synchronous generator, switched between off-grid and grid-interfaced modes and vice-versa, which eliminates the need for synchronizing tools such as phase-locked-loops, and separate islanding detection techniques during unintentional islanding events.

Wireless-Control Strategy for Parallel Operation of Distributed-Generation Inverters
TL;DR: Adapt virtual output impedance is proposed in order to achieve a proper reactive power sharing regardless of the line impedance unbalances and can be properly shared due to the addition of a current harmonic loop in the control strategy.
