Welcome to DynPOWER 2022

GENERAL INFORMATION

We are in a post-pandemic time, where fundamental activities are gradually returning back to normal. Although we are still in times of uncertainties of a different character, it is possible to meet again face to face, and we want to use this new opportunity to once again hold our international workshop.

Energy transitions worldwide are a reality and are in the process of implementation. Although global geopolitical circumstances can impact the future development plans, there still technical questions open that urge to be answered.

In this context, the international workshop is an open free forum that brings together experts from industry and academia from all over the world, where their most recent developments to overcome these inherent challenges are discussed. The event aims to address challenges related but not limited to the operation, monitoring, protection and control of the future power grids.

The workshop will take place on Monday 19th of September 2022, in the city of Winterthur, Switzerland. The venue is the CASINOTHEATER, which is at the heart of the city centre. The event will take place in a hybrid form, this means that we will host up to 50 persons on site and the presentations will be in parallel live streamed for the international audience that we have gained over the last two years.

► Power system monitoring and state estimation under dynamic conditions: a measurement perspective

The effective management of modern power systems requires the availability of suitable monitoring architectures, designed to achieve specific performance objectives for the quantities of interest. Power systems control centres require accurate and high-rate information to track on-going dynamics, to support timely decision making and to obtain effective contingency analysis, fault detection and protective actions. New generation instruments, like Phasor Measurement Units (PMUs) and Smart Meters, have huge potentialities in Power Grid Monitoring and, in particular, in state estimation applications. However, their performance under dynamic conditions is much different from that claimed in their specification or assessed via compliance tests. In addition, innovative procedures that allow considering different and adaptive values of the accuracies of different measurement devices in the estimation process are needed. Measurements from heterogeneous devices and information concerning the uncertainties to be applied in the estimation process, considering the actual operative state of the monitored nodes, need to be collected and used. The presentation will focus on these aspects of the monitoring process and aims at being twofold: give a measurement perspective with concrete examples and suggest possible routes for new generation monitoring systems.

► Cybersecurity Challenges for Cyber-Physical Energy Systems Stability

Rapid advancements in power electronics along with the increasing penetration of distributed energy resources (DERs) are transforming the electric power grids. Furthermore, increasing types and number of loads and electric transportation are stressing the network. Overall, the power system is facing unprecedented changes in operation and control as more and diverse sources and loads are being connected to this complex cyber-physical energy system. In light of this modernization, and due to the growing number of Internet-of-things (IoT) connected controllers, and the use of communication and control interfaces, making the CPES resilient to high-impact, low-probability cyber-physical adverse events, such as cyber-attacks, is a major priority for power grid operations. Such incidents, if left unabated, can intensify and elicit system dynamics instabilities, eventually causing outages and system failures. In this talk, we will give an overview of the research of the Secure Next Generation Resilient Systems (SENTRY) lab (sentry.kaust.edu.sa) at KAUST, presenting different methodologies, in the age of renewable energy, contributing toward building secure and stable cyber-physical grids.

► Hardware-in-the-Loop Testing for Grid Stability and Resilience

We are standing on the threshold of a new electrical revolution. Global events are driving the need for more locally managed and sustainable power systems. Often, this means integrating renewable energy sources coupled with novel energy storage systems into the existing grid infrastructure. However, transforming the energy system comes with significant grid stability, safety, and resilience challenges. The successful digitalization, decentralization, and decarbonization of power systems requires software that will control and aggregate numerous distributed energy sources and loads simultaneously. This software needs to be tested, and this is only possible with the help of specialized advanced tools that are the core business of Typhoon HIL.

► Real-Time Co-Simulation of Transmission and Distribution Networks with Frequency and Voltage Optimal Control

The real-time power hardware-in-the-loop co-simulation is a cost-effective, low-risk and highly repeatable alternative for testing the impact of modern control schemes for frequency and voltage support of transmission networks by exploiting the power injection of battery energy storage systems (BESS) on the frequency and voltage regulation of the power network. In this context, the viability and dynamic performance of an optimal hierarchical closed-loop control framework are experimentally verified in a laboratory environment with the successful interconnection of several real time emulators of different brands and power hardware-in-the-loop.

► Modelling of the European power system for dynamic simulations in current and future scenarios

The European power system is projected towards a transformation process related to the worldwide commitment for clean energy. A strong increase of renewable energy sources and the corresponding curtailment of synchronous generation are therefore expected. In this context, the development of accurate simulation models of the European system plays a fundamental role in the analysis of potential future scenarios, dominated by converter-interfaced generation sources. The presentation will give a preliminary overview of the existing models of the European power system, and then it will focus on the large-scale dynamic model of the Continental Europe synchronous area provided by the ENTSO-E. This model has been extended, replacing different amounts of synchronous generation and introducing the corresponding amount of non-synchronous generation sources. These modifications are intended to reflect future scenarios, and they will be shown as application cases. Modal analysis and time-domain dynamic simulations of the European system will be presented, and the results will bring to attention some relevant considerations about the frequency dynamics and the oscillatory behavior of the system in converter-dominated scenarios. Finally, the derivation of equivalent dynamic models from the large-scale model of the European power system will be also discussed.

Rossano Musca received the PhD degree in Electrical Engineering at the University of Palermo (Italy) in 2010. In the period 2011-2018, he worked for the software company NEPLAN AG, Zürich (Switzerland), leading the development of the "Dynamic Analysis" (RMS and EMT) and the "Small Signal Stability" simulation modules. Since 2018, he is a researcher at the University of Palermo, where he works mainly on stability and control of power systems, with a focus on the dynamic aspects related to large integration of converter-based generation, power system damping, and oscillations, grid-following and grid-forming advanced controls.

► Analysis of the two systems splits within the Continental European Synchronous Area in year 2021

During year 2021, the Continental European (CE) Synchronous Area faced several incidents that seriously challenged its interconnected nature. Thanks to the close collaboration of European TSOs through the ENTSO-E, and thanks to the inherent resilience of such a large power system, none of these events lead to catastrophic consequences and the system was brought back into a safe operating mode after a few hours. First, on January 8th due to a large power flow from South-East to North-West Europe, cascaded trips of several transmission elements split the system into two separate regions, with the separation line crossing Croatia, Serbia, and Romania. Then, on July 24th the Iberian Peninsula was separated from the rest of the CE power system due to a wildfire in the eastern French double circuit near the Spain-France interconnection that triggered the automatic protection devices of the tie-lines and led to further cascaded trips.

The ENTSO-E Subgroup System Protection and Dynamics had a leading role in carrying out the technical investigations that followed these events and actively contributed to the definition of future recommendations. The tutorial/panel expands on the methods and tools that were used during such investigations, with a particular focus on dynamic stability criteria.

Asja Derviškadić received the B.Sc. and M.Sc. degrees (Hons.) in electrical engineering from the University of Rome "La Sapienza," Rome, Italy, in 2012 and 2015, respectively, and the Ph.D. degree in electrical engineering from the Swiss Federal Institute of Technology of Lausanne (EPFL), Lausanne, Switzerland, in 2019. From 2019-2020 she was a Postdoctoral researcher at the Distributed Electrical Systems Laboratory (DESL) of EPFL and her research interests focused on synchronized sensing technologies for wide-area situational awareness of electrical grids operating in non-stationary conditions. She is currently with the short-term network modeling team of Swissgrid, the Swiss transmission system operator, where she works as a grid studies engineer. She is a member of the ENTSO-E Subgroup System Protection and Dynamics.

► Systems for supporting power system operation of modern TSO

Transmission System Operations are faced with challenges such as very fast an high integration of renewables, fast dynamic changes in the network, congestion managing and so on. Despite all the challenges, the system must still remain reliable and stable. To facilitate system operation in these challenging conditions, the new system are implemented in the control room.

One of them is the wide area monitor (WAM) system that gives to a dispatcher in the control room a real-time picture of the grid state in terms of stability through angle difference or oscillating monitoring. Also, the WAM system, through the implemented algorithms reports conditions such as the appearance of asymmetry in the network, broken conductor, or island detection.

Besides that, one of the newer systems is the dynamic thermal rating (DTR) system which has been installed on the critical power lines that are often highly loaded. For those power lines, DTR gives the prediction of transfer capacity for the purpose of planning and real-time estimation of the transfer capacity based on the weather forecast in the vicinity of the power line and the power line parameters measured. The results of DTR system are used in real-time applications for security analysis and day-ahead power flow-based forecast calculation.

► Applications of Real-Time Digital Twin Simulation along with WAMS for improving the power system dynamic security

The operation of electric power systems is experiencing several technical challenges associated with the new paradigms of management and planning such as the inclusion of deregulated markets, the interconnection with neighbouring regional systems, the diversification of energy sources, the inclusion of environmental constraints and even the massive penetration of renewable generation plants. Under these conditions, unexpected disturbances may cause violations to the security limits established for the electric power system leading to the outage of important system elements and even partial or total blackouts. Real-time monitoring of the static and dynamic security of the power system plays a fundamental role inside the applications used in Control Centers; however, proper analytics need to be performed by operators in order to be prepared for tackling the phenomenon both in planning and real-time operation stages. In this connection, the combination of synchrophasor measurement systems (PMU/WAMS) together with advanced real-time simulations can give enough information for improving the planning and operations decision-making. This presentation shows the experiences of the Ecuadorian Electricity Operator on structuring a Testbed for PSS Tuning using eMEGAsim and an Operators’ training Environment using ePHASORsim, both along with the WAMS platform WAProtector.

Jaime Cepeda is an Ecuadorian Electrical Engineer. He got the Ph.D. degree at Universidad Nacional de San Juan, Argentina in 2013 and the Master degree in Big Data at Universidad Europea Miguel de Cervantes, Spain in 2021. His doctoral thesis was awarded by the “Domingo Faustino Sarmiento” 2014 prize, he was also recognized by the MIT Technology Review Innovators under 35 award in 2015, and he obtained a prize for Innovation on Digitalization from CIER in 2021 for PSS tuning using WAMS. He has been the Chief Executive Officer at Ecuadorian Agency of Energy and Non-Renewable Resources and the Head of Research and Development Department at National Electricity Operator CENACE. At present, he also serves as part-time University Professor in Master and Doctoral Programs. His special fields of interest comprise power system operations, WAMS, and application of big data and machine learning into power systems.
