Item type:Publication, Access status: without files , Real-time Test Platform for Enabling Grid Service Virtualisation in Cyber Physical Energy System(2020-09-01); ; ; ; The challenge of reliable operation in Cyber-Physical Energy Systems (CPES) is constantly increasing due to more participating actors and associated disruptive events. The supporting automation systems for monitoring, communication and control is a vital part for reliable operation, realized by grid services such as voltage control, frequency control, system restoration. However, to ensure the availability of these services during and after disruptive events is challenging. Management technologies such as virtualization are key drivers to provide the necessary flexibility to reallocate, orchestrate and update such grid services. This paper introduces a multidisciplinary real-time test platform for integration of grid service management in CPES. Furthermore, a detailed description of the test environment including real-time power system simulation, communication system simulation, grid virtualisation management kit and virtualized hardware-software components are provided. Finally, the test platform is evaluated by a set of scenarios for modified CIGRE MV grid and its communication infrastructure.Publicationtype: Conference Paper42 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Virtualization management concept for flexible and fault-tolerant smart grid service provision(2020-05-02); ; ; ; In modern power systems, reliable provision of grid services (e.g., primary and ancillary services) are highly dependent on automation systems in order to have monitoring, processing, decision making and communication capabilities. The operational flexibility of automation systems is essential for the reliable operation of power systems during and after disruptive events. However, this is restricted by integrated hardware-software platforms. Therefore, it will be difficult to reconfigure control strategies during run time. This paper presents the concept of Grid Function Virtualization (GFV) as a potential approach to improve the operational flexibility of grid automation systems. GFV has been proposed to offer a new way to deploy and manage grid services by leveraging virtualization technology. The main idea of GFV is to run grid services (i.e., software implementation of services) independently from underlying hardware. To realize the important design considerations, the GFV architecture and its building blocks is elaborated in details. To this end, an exhaustive review of applications of virtualization in several domains is provided to show the importance of virtualization in improving flexibility and resource utilization. Finally, the advantages of the proposed concept to deal with disruptions in power systems is demonstrated in a proof of concept based on a CIGRE MV benchmark grid.Publicationtype: Journal Article45
