Optimal Control for Improved Damping of Virtual Synchronous Machines
2020 IEEE PES Innovative Smart Grid Technologies Europe (ISGT-Europe), 2020The fraction of generation from power electronics driven Distributed Energy resources (DERs) is increasing. Therefore, DERs must also take up functionalities, such as inertia provision and oscillation damping, traditionally offered by synchronous generators (SG).

vMPCP: A Synchronization Framework for Multi-core Virtual Machines
2014 IEEE Real-Time Systems Symposium, 2014The virtualization of real-time systems has received much attention for its many benefits, such as the consolidation of individually developed real-time applications while maintaining their implementations. However, the current state of the art still lacks properties required for resource sharing among real-time application tasks in a multi-core ...

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 ...

A synchronization controller for grid reconnection of islanded virtual synchronous machines
2015 IEEE 6th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2015The control of power electronic grid interfaces as Virtual Synchronous Machines (VSMs) is emerging as a suitable approach for converters in distributed power systems. VSM implementations including an internal model of a virtual inertia can also inherently allow for both grid-integrated and standalone applications.

A Simplified Synchronous Machine Model for Virtual Synchronous Generator Implementation
2019 IEEE Power & Energy Society General Meeting (PESGM), 2019Virtual Synchronous Generator control of inverters is one of the promising solution to the insertion of renewable energies on Microgrids which still insure the system's stability. In this paper an improved synchronous machine model for the VSG-based inverter is proposed. The model represents the dynamics of the synchronous machine and has the advantage

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.

Algorithm for Virtual Synchronous Machine Phase Resynchronization
2018 9th IEEE International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2018In this paper, the idea of operating parallel inverters to mimic the dynamic stability of a synchronous generator (SG) is investigated when the inertia and damping constants are differed. These inverters are virtual synchronous machines (VSM) due to the replication of the inertial dynamics inherent to the SGs. Instead of using a conventional Phase-Lock

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.

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 ...
