Virtual synchronous machines with fast current loop
Abstract Virtual synchronous machines (VSM) are inverters that behave towards the power grid like synchronous generators. One popular way to realize such inverters are synchronverters, whose control algorithm has evolved over time, but both theoretical analysis and practical observations show that the output currents of a synchronverter are very ...

A Parallel Virtual Machine for Bulk Synchronous Parallel ML [PDF]
We have designed a functional data-parallel language called BSML for programming bulk-synchronous parallel (BSP) algorithms. The execution time can be estimated and dead-locks and indeterminism are avoided. The BSMLlib library has been implemented for the Objective Caml language.

Review on grid-forming converter control methods in high-proportion renewable energy power systems
Grid-forming (GFM) converters can provide inertia support for power grids through control technology, stabilize voltage and frequency, and improve system stability, unlike traditional grid-following (GFL) converters.

A Comprehensive VSM Control Strategy Designed for Unbalanced Grids
A virtual synchronous machine (VSM) is a converter which, compared to other types of converters, has more friendly interactions with the power grid because it is able to simulate the external characteristics of a synchronous machine, which can provide ...

From BSP to a virtual von Neumann machine
Bulk synchronous parallel architecture incorporates a scalable and transparent communication model. The task-level synchronization mechanism of the machine, however, is not transparent to the user and can be inefficient when applied to the coordination ...
