An Improved Damping Method for Virtual Synchronous Machines
IEEE Transactions on Sustainable Energy, 2019A virtual synchronous machine (VSM) approach is proposed to integrate inverter-based distributed energy resource units into the power and energy system. VSMs emulate the model of a synchronous machine in the inverter's controller. Among different aspects, emulating the damper windings or devising an alternative damping strategy is critical.

Efficiently Synchronizing Virtual Machines in Cloud Computing Environments
2011 IEEE Third International Conference on Cloud Computing Technology and Science, 2011Infrastructure as a Service (IaaS), a form of cloud computing, is gaining attention for its ability to enable efficient server administration in dynamic workload environments. In such environments, however, updating the software stack or content files of virtual machines (VMs) is a time-consuming task, discouraging administrators from frequently ...

Energy storage configuration strategy for virtual synchronous machine
2016 IEEE Energy Conversion Congress and Exposition (ECCE), 2016This paper investigates energy storage configuration strategy for virtual synchronous machine (VSM). The proposed VSM provides virtual inertia and damping to maintain stability of grid. Virtual inertia and damping need to be established by energy storage system (ESS).

Synchronous Evacuation for Dual Virtual Machines Under Disaster Risks
2020 43rd International Conference on Telecommunications and Signal Processing (TSP), 2020Network virtualization enables Internet service providers to flexibly provision heterogeneous virtual networks (VNs) over shared substrate networks (SNs). As more and more applications are carried by VNs, the survivability of VNs becomes a critical challenge under large-scale disaster risks.

Automated virtual prototyping of permanent magnet synchronous machines for HEV's
Digests of the 2010 14th Biennial IEEE Conference on Electromagnetic Field Computation, 2010Ecological awareness has spurred a renewed interest in hybrid electrical vehicles (HEV), because of their ability to combine the drive power of a combustion engine with that of electrical machines. PMSM's notoriously offer large torque/weight ratios and are therefore particularly well suited for inclusion in HEV drivetrains, where the available space ...

Virtual synchronous machine control with virtual resistor for enhanced short circuit capability
2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe), 2017Increasing shares of power electronic converters in renewable generation challenge power system stability. For very high shares the state of the art current-control approach should be replaced by grid forming control schemes. The virtual synchronous machine (VSM) approach is grid forming and fully compatible to conventional synchronous-machine-based ...

Control of modular multilevel converters as virtual synchronous machines
2017 IEEE Power & Energy Society General Meeting, 2017Modular multilevel converters (MMC) have been a research focus in high-voltage power conversion, covering modulation techniques, capacitor voltage balancing and circulating current control. In this paper, a control method is proposed to control MMCs to behave like virtual synchronous machines (VSM). It can be operated in the set mode and the droop mode.
