  • Power Quality Performance: Continuity of end-to-end electric power supply and voltage waveform quality (magnitude, frequency, symmetry). Analysis covers emission assessments from disturbing installations, measurement and simulation methods, identification of quality indices, monitoring techniques, immunity of sensitive installations, and mitigation techniques taking into account a co-ordinated approach across all voltage levels.
  • Electromagnetic Compatibility (EMC): High frequency disturbances on the end-to-end electricity supply and all disturbances (HF or LF) reaching equipment other than through the electricity supply. Studies include measurement and simulation methods. Health effects related to low frequency EMF are however excluded.
  • Power System Dynamics: Development of advanced tools and new analytical techniques for assessment of power system dynamic/transient performance, security, design of controls and modelling of existing and new equipment, real time stability evaluation and control.
  • Lightning: Analysis of lightning characteristics and interactions of lightning with electric power systems and equipment, including protection in MV and LV networks against lightning, and their standardisation.
  • Insulation Co-ordination: Methods and tools for insulation co-ordination and electromagnetic transient analysis in electric power systems and equipment, contributing to optimisation of their cost and reliability.

  • Environmental impacts of power system development and operation, sustainable development vs. economic development, risk assessment and the economics of impact containment, power system efficiency and the environment
  • Stakeholder engagement and communication, effective communication with the public and regulatory authorities, public acceptance of power system infrastructure
  • Tools and measures for quantifying, controlling and mitigating the environmental impact such as life-cycle assessment (LCA), environmental product declarations (EPD), global benchmarking, etc.
  • Global environmental changes relevant to the power system, awareness of the activities of global organisations in the environmental field and establishing appropriate co-operations and liaisons.

C2 Power System Operation and Control

  • Control, monitoring and switching of equipment, management of ancillary services (such as voltage control, frequency control), monitoring of operational limits and actions to maintain network security and to avoid congestion (e.g. congestion management). Reserves and emergency strategies, management of disturbances, restoration and resilience enhancement strategies, interaction between the system players. Use of PMUbased data (such e.g. WAMS, WAMPS and WAMPACS), their integration within control centre environment and its contribution to power system analysis and security assessment functionalities.
  • Developments and changes in the business of System Operators and their integration into the evolving environment: energy transition impact, changes in costumer behaviour, integration of new technologies, management and operation of large-scale energy storage, operation from pure AC to hybrid AC/DC systems, including cross-border interconnection, and common and coordinated activities between System Operators, between Transmission, Distribution and service providers. Consequences of higher penetration of DG/RES resources, increasing information exchange and controllability coming from all voltage levels. Interaction with market players, regulators, and service providers.
  • Evaluation and benchmarking of the system performance in terms of disturbance frequency, power interruptions, power quality, operational and outage planning efficiency, both from the technical and economical points of view.
  • Requirements, methods, tools and performance indicators for Control Centres and training of System Operators.
  • Short-term planning and coordination of capacity calculation and network security. Development and use of power system analysis and security assessment functionalities within operational planning and real-time supervision, supporting system operators. Automation of processes and optimisation, e.g. application of remedial actions.

  • Utilization of methods and tools for power system steady state and dynamic analysis in system planning and economic analyses.
  • Planning predicaments and methods in competitive and regulatory structures and with stakeholder involvement for public acceptance. Progress and new approaches in application of power system planning criteria and reliability (security, adequacy, resilience) assessment.
  • Capacity enhancement by use of risk-based security assessment and advanced information, communication and power-electronics technology for improving system stability and dynamic performance.
  • Future dependence, requirements and economy of ancillary services for frequency and voltage control and other system needs (grid codes).
  • System planning issues in newly industrialised and developing countries including metropolitan areas.
  • Asset management strategies applied across a range of power system assets for the definition of optimal policies using e.g. total life cycle cost of ownership.
  • Impact on system development of new solutions and technologies in fields such as generation, demand side management (DSM), energy storage, “smart” and evolving distribution systems. • The impact of pricing and tariff methods for transmission services on system development and project priorities in the context of market design and grid ownership structures.
  • Planning issues related to long distance transmission and international interconnections. • Interface and allocation issues in transmission and distribution planning, and delivery of multi-party/cross-jurisdiction projects.

2025 B3 Technical Presentation – Video

  • Issues in all phases of the substation lifetime; from conception, through research, development, design, production, deployment, operation and end-of-life.
  • At all stages, technical, safety, economic, environmental and social aspects are addressed, as well as interactions with and integration into the evolving power system and environment.
  • All aspects of performance, specification, testing and the application of testing techniques are within the scope, with particular emphasis on the impact of changing interactions and requirements due to the evolution of the power system.
  • Life cycle assessment techniques, risk management techniques, education and training are also important aspects.
