Special Issue Information

Dear Colleagues,

Power systems around the globe are faced by the need to decrease environmental and climate footprints of our electricity and energy use. Technological advances and legislative framework are further increasing the speed and impact of the evolutionary process of the power systems.

Operating and controlling of electrical power systems in the future cannot be done based on the same strategies which have been used in the past. Future scenarios are diverging to such extent that historical knowledge cannot be used to plan ahead without proper methods and tools. Furthermore, new dynamic phenomena are arising which requires novel solutions to analyse and to mitigate.

Advances in control and analysis of power systems are thus imperative to maintain a reliable and secure power system in the future.

The aim of this special issue is to provide examples of developments in power system analysis and control supporting the sustainable development of the electrical power systems.

Potential topics include, but are not limited to:

Methods and tools for operation and operational planning
Advanced control solutions for secure operation
System Integrity Protection Schemes
Techniques for analysis of dynamic phenomena

Digital Twin Development of a Dynamic Hardware Emulator

by Sandro Kellermüller, Artjoms Obushevs, Miguel Ramirez Gonzalez and Petr Korba

Abstract

The increasing deployment of new technologies to contribute to the decarbonization of power systems is imposing new challenges in terms of system dynamics and stability. To deal with different operating and control issues in this sense, and support actual needs, advanced tools and solutions are required. Therefore, this paper presents a digital twin of a dynamic hardware emulator that can be used for controller hardware in the loop (CHIL) testing and is based on a small-scale laboratory system. To build the simulation model, the parameters of involved synchronous machines, excitation systems, prime movers and transmission lines have been identified and then compared to laboratory measurements to assess the accuracy of the digital twin. Static and dynamic accuracy have been investigated and an overall good accuracy can be shown with the help of quantification of errors. Furthermore, a case study is presented where the digital twin was used to design a controller to damp inter-area oscillations with the help of wide area measurements. This controller was then implemented and tested within the dynamic hardware emulator in the laboratory. Full article

System Integrity Protection Schemes: Naming Conventions and the Need for Standardization

by Stefan Stanković, Emil Hillberg and Susanne Ackeby

Abstract

The energy transition is placing increased strain on power systems and making it challenging for Transmission System Operators (TSOs) to securely operate power systems. System Integrity Protection Schemes (SIPSs) are one of the solutions to address these challenges. SIPSs are a type of over-arching power system control; their goals are to increase the secure utilization of power system assets and to limit the impact of large disturbances on the system. Due to societal developments, the interest in utilizing SIPSs is increasing internationally, highlighting the importance of the standardization of terms and definitions to support collaboration between internationally interconnected power systems. This paper addresses the issue of increasing SIPS literature and the efficient exchange of knowledge about SIPSs by providing a new, up-to-date literature review and proposal for the standardization of SIPS terminology. The need for standardized terminology is highlighted by gathering various terms used to describe SIPSs and proposing a standardization of definitions, terms, and SIPS operational execution steps. The goal of the proposed standardization is to provide clarity and to decrease the sources of misinterpretation in an international collaborative environment. The analyzed literature is further classified according to the SIPS features it addresses, and conclusions about well-established and interesting future research areas are drawn. For example, it has been observed that the most commonly considered SIPS action is load shedding, while more sophisticated actions, e.g., using HVDC (High Voltage Direct Current) and FACTS (Flexible AC Transmission System) installations, controlled together with var rescheduling, are more in the realm of future research that may provide additional benefits to TSOs.
