Very Large Power Grid Operators (VLPGO)
Formation of the VLPGO A voluntary initiative of the world’s largest Power Grid Operators Representing together more than 60% of the electricity demand
in the world. Created in 2004 Not-for-profit organization Followed several blackouts across the world To investigate fundamental issues of common interest to its members To develop joint action plans addressing the improvement of power system security. Formalized in 2009 Specific Focus Issues related to Very Large Power Grids Membership Size > 50 GW
VLPGO : Role of Grid Operators Worldwide Work constantly to plan, monitor, supervise and
control the energy delivered as a continuous process 24 hours a day Delivering the electricity that powers modern societies Critical role of Grid Operators includes
acting on behalf of Consumers, to ensure quality while minimizing costs and recognizing economic and societal dependence on electricity; a technical role in planning, designing, and managing the Power Systems; an interface role with generators, market participants and distributors, which are the most direct users of the transmission grid; a natural role of interlocutors with power exchanges, regulators and governments.
Common Challenges for VLPGO Providing power system reliability and security Smart Grid development Integration of Renewables Integration of Electric Vehicles Capacity development and optimization including system
renovation and development, equipment upgrading. Reducing CO2 emissions Improve productivity and energy efficiency Power system visualization Demand Side Management Interconnections Development of new technologies and HVDC Establishment and coordination of new control centers 10
VLPGO Vision and Mission Vision

Benchmarking Model The TSO Comparison Group is using an advanced
multidimensional Benchmark Model for comparing TSOs’ System Operation organization. The Model’s “multidimensional approach” provides insight into
the efficiency and effectiveness of each TSO with respect to both its own environment (size, structure, regulation et al) and to other TSO environments. The Model’s output has demonstrated the capability of
identifying generic differences (resulting in ad hoc peer-groups) as well as generic similarities. The Model’s output has been utilized for mergers (in defining
staff sizing requirements), and tested for self-analysis (in validating actual staff sizes).
Features of the benchmarking model The model aids in highlighting the effects of non-traditional
changes within peer groups.
As non-traditional changes, such as new Market initiatives are
developed, the Model will display the areas of change.
Although the value of those changes will vary with corporate
objectives, the magnitude and the areas impacted by the changes will be highlighted by the Model.
The key feature of the Model is that it does not focus on defining
the “best” and the “worst” TSOs, but rather focuses on identifying differences between TSOs.
Whether differences are good or not will depend on many factors
– the Model allows the user to make those value decisions based on the goals of the respective user.
For Benchmark purposes a ‘standard TSO’ with five key System Operation processes has been defined..

..and a process which takes into account the remaining differences between TSOs
Data Collected annually since 2000, validated by KEMA, verified by group Example of data points: Operations Planning (1 year to 2 weeks before day of operation) − Number of Planned Transmission Outages − Number of Planned Generating-unit Outages Scheduling (2 weeks to 1 day before day of operation): − Accuracy of peak load forecast − Accuracy of minimum load forecast − Transmission congestion: Generation constrained "on". − Foreseen transmission concerns − Scheduled transmission outage requests − Scheduled generation outages Real Time Operation (Day of Operation): − Frequency control performance − Average overall system deviation − Generation and load instructions − Personnel on shift − RTO transmission outages taken
Support − Operator training hours of teachers − Number of SCADA database points (Status points, Analog points, Control points) Overall Performance: − Transmitted energy at risk − Response Time of Area Control Error or Frequency − Energy unsupplied due to 'unsupplied energy incidents' − Unsupplied energy incidents − Voltage excursions Reference Data − Number of Staff in Full Time Equivalents, separately for each process − Costs, separately for each process and network losses − Network date, including e.g. Circuit Ends, Line lengths, Generators, Peak Load, Transmitted Energy, Interconnectors.

CIGRE (INTERNATIONAL COUNCIL ON LARGE ELECTRIC SYSTEMS)
Aim CIGRE (International Council on Large Electric
Systems) is one of the leading worldwide Organizations on Electric Power Systems, covering their technical, economic, environmental, organisational and regulatory aspects. A permanent, non-governmental and non-profit International Association, based in France, CIGRE was founded in 1921 and aims to:
Facilitate the exchange of information between engineering personnel and specialists in all countries and develop knowledge in power systems. Add value to the knowledge and information exchanged by synthesizing state-of-the-art world practices. Make managers, decision-makers and regulators aware of the synthesis of CIGRE's work, in the area of electric power.
CIGRE: Developing Technical Knowledge CIGRE develops technical knowledge through 3 types
of activities: - Organizing Conferences and meetings, where papers are discussed, - Carrying out Permanent studies by 16 Study Committees, each dealing with a specific technical field, publishing reports and organizing Tutorials. - Making its publications available to members of CIGRE and others.
Study Committee C2 - System Operation and Control The Study Committee C2 serves within Cigré by forming a
working concept for the functionalities, structures and competence needed to operate integrated power systems in a way that is in compliance with the social requirements for security of electricity supply.
The performance of power systems in real time depend on
technical quality factors built into the systems through various activities and knowledge currently covered by the other Cigré Study Committees. SC C2 therefore needs to use and combine results provided within these committees.
An area which is unique for C2 is however the dependency on a
good performance of human resources in real-time system operation activities.
In these respects SC C2 encircles a wide range of competence
areas and interfaces to other disciplines.
Mission and Scope of CIGRE Study Committee C2 Mission of SC C2:
To facilitate and promote the progress of engineering and the international exchange of information and knowledge in the field of system operation and control. To add value to this information and knowledge by means of synthesizing state-of-the-art practices and developing recommendations. The Scope of SC C2:
The scope of the SC covers the technical, human resource and institutional aspects and conditions for a secure and economic operation of existing power systems under security requirements against system disintegration, equipment damages and human injuries
Driving forces for future work The priorities to important emerging factors that will
influence and define new requirements on the System Operation performance. Directions are:
Integration of regional and national grids into large open markets Management of generation capacity and energy shortages Management of capacity shortages Impact from new sources of dispersed generation and related system requirements Influence from customer needs and response Interaction between open market trading mechanisms and power system operation in congestion and transit flow management Integration of information and communication technology
