4 4 FG System Operation, Public Workshop, , ACER/Ljubljana Scope. Special focus on the interoperability among all TSOs connected to the synchronous areas.. All TSOs actions with regard to System Operation within a synchronous area or between them bear cross-border character due to law of physics.. Rulebooks already exist in the different synchronous areas, but the debate with the Expert Group revealed problems that have not been tackled by these rules. Hence, a more coherent framework is needed. Technical operation of the interconnected grid, including generation control, performance monitoring and reporting, reserves, security criteria and specific operational measures.

7 7 FG System Operation, Public Workshop, , ACER/Ljubljana Background Originally, European transmission networks have been developed on a national basis. Their increasing interconnection has largely been carried out to provide the power systems with better operational security and to pool power reserves.

8 8 FG System Operation, Public Workshop, , ACER/Ljubljana General Context. Existing agreements. Increase of flows and transactions at interconnections. Opening and integration of the electricity markets and increased number of electricity market participants. Integration of variable energy resources and demand side response Safe and secure technical operation of the electrical network is a prerequisite to develop an efficient energy market, without creating any barriers (1)Security of Supply (2)Integrated Energy Market (3)2020 Targets on RES, CO2 and energy efficiency 3 main drivers on EU level

9 9 FG System Operation, Public Workshop, , ACER/Ljubljana Problems Need for more — and better — information exchange Misunderstan- dings in system planning and operation Hard to forecast power flows Lack of real- time information 1 Increasing interdepen- dence of control areas Growing amount of distributed and variable gene- ration capacity Lack of rules between synchronous areas 234 Lack of aware- ness of the roles Gaps and overlaps in existing rules Severe system failures due to not matching requirements Uncoordinated trippings and reconnections Generation connected at distribution level  Limited observability and control  Differing rules Lack of reliable generation information Integration of DC lines Equivalent rules do not exist for interconnectors

11 11 FG System Operation, Public Workshop, , ACER/Ljubljana General Objectives. Safe and secure system operation has highest priority to ensure full integration of the energy markets. To develop a harmonised system operation regime that does not compromise the security and stability of the power systems, enabling at the same time the proper functioning and technical evolution of the European electricity market and transmission network through coordinated action from TSOs, DSOs and grid users. Achieving and maintaining normal functioning of the power system with a satisfactory level of security and quality of supply, as well as efficient utilisation of infrastructure and resources. Safe operation of the European electrical systems:  From agreements to binding codes

12 12 FG System Operation, Public Workshop, , ACER/Ljubljana Specific Objectives (1) To operate the electrical system in a safe, secure, effective, efficient manner Maintain and improve system safety and security Operate the electrical system in a safe and secure manner within normal operation limits including cooperation between TSOs and DSOs and grid users Reduce the number of critical incidents, avoid major incidents  and limit the consequences when they occur Provide conditions for specific, ongoing human resources development 1 To enable the integration of innovative technologies 2 Enable the integration of renewables, especially regarding variable generation Prepare the network for integrating distributed generation Make efficient and effective use of smart grid applications Provide conditions for exploiting the demand-side potential Enable the integration of advanced power electronic systems and meshed DC-lines concepts

13 13 FG System Operation, Public Workshop, , ACER/Ljubljana Specific Objectives (2) To apply the same principles for different systems Apply same principles  ensure strict rules within synchronous areas  have modified rules across asynchronous systems Improve alignment of European rules (technical standards) in third countries connected to ENTSO-E systems 3 To make full use of information and communi- cation technologies 4 Provide conditions for improved data collection, handling and exchange Provide framework for compatibility of e.g. forecast, simulation and modelling tools Strengthen the TSOs and DSOs in terms of auditing and monitoring capabilities and performances of generation units and consumers

15 15 FG System Operation, Public Workshop, , ACER/Ljubljana FG Structure Key ChallengesObjectivesTopics Security Criteria TSOs‘ Roles, Methods Data Exchange To operate the electrical system in a safe, secure, effective and efficient manner To apply same principles for different systems To make full use of information and communication technologies To enable the integration of innovative technologies The key challenges are identified to highlight existing and expected future problems within system operation. The objectives go one step further and translate the diffuse challenges into bounded target statements, which subsequently provide base for policy option analysis. A final modification spreads the objectives on core processes of system operation, in order to enhance both, execution of the selected policy option in the Framework Guidelines and operational implementation as Network Codes.

18 18 FG System Operation, Public Workshop, , ACER/Ljubljana General. Providing comprehensive definition section. Key content is organised in tables, based on common properties: » Scope & Objectives » Criteria » Methodology & Tools » Roles & Responsibilities » Information Exchange » Implementation Issues

19 19 FG System Operation, Public Workshop, , ACER/Ljubljana Operational Security. Ensuring - on a high level - coherent and coordinated behaviour of bulk transmission networks and power systems in each control area under normal operation, in alert (disturbed) operating states as well as in critical (emergency) operating states.. Achieving and maintaining a satisfactory level of operational security allowing for efficient utilisation of the power system and resources, including, but not limited to, the necessary inputs to congestion management and balancing.. Avoiding further deterioration of operational security in cases, where security constraints are violated and systems are not in normal operating state.

20 20 FG System Operation, Public Workshop, , ACER/Ljubljana Operational Planning & Scheduling. Ensuring coherent and coordinated behaviour of transmission networks and power systems in preparation of real-time operation.. Achieving and maintaining a satisfactory level of operational security and efficient utilisation of the power system and resources.

21 21 FG System Operation, Public Workshop, , ACER/Ljubljana Load-Frequency-Control. Real-time operation of an electric power network requires a balance between generation and load, whereas deviations impact the system frequency. Hence, load-frequency-control is a core task of System Operation, with the main features: » Ensuring coherent and coordinated behaviour of transmission networks and power systems in real-time operation. » Achieving and maintaining a satisfactory level of frequency quality and efficient utilisation of the power system and resources.

22 22 FG System Operation, Public Workshop, , ACER/Ljubljana Staff Training & Certification. The transmission system operators working at control rooms must be properly trained to make decisions in ensuring secure and efficient network operation. The aim is to develop and maintain the transmission system operators’ skills adequately.. Common training principles and standards - and finally certification - shall ensure smooth cooperation and coordination up to European level.. The certification shall extend primarily to the TSO organisation and lead transmission system operators in charge (e.g. shift engineers).

23 23 FG System Operation, Public Workshop, , ACER/Ljubljana Emergency & Restoration. The remedial actions may include e.g. the activation of active or reactive power reserves, automatic load shedding or any other emergency measure.. Recovery or restoration from the alert or critical, to the normal operating state shall occur as fast, effective, reliable and efficient as possible in order to avoid new disturbances and/or further deterioration of system security.. Ensuring that all efforts in restoration after a major disturbance or a blackout are well coordinated and led by the TSOs within a synchronous area and that no individual measures or attempts to restoration of supply adversely affect the overall common goal of the re-establishment of System Operation as soon as possible.

24 24 FG System Operation, Public Workshop, , ACER/Ljubljana New Applications. Addressing new requirements and future needs for respective consideration in the System Operation framework of the issues listed below should be covered by Network Codes. » Integration and operation of DC bulk-power-transport lines, for “collecting” the massive wind power and solar-thermal generation. » Methods and tool enabling high-level and efficient TSO coordination during the operational planning and real-time system operation, like adequate operational observability. » Dynamic rating of power cables and overhead transmission lines. » Close interaction of the future integrated electricity balancing markets of Europe with the intraday trade and manually activated (tertiary) reserves. » Coordinated usage of phase-shifting transformers and/or FACTS for active load flow control and system stability augmentation.. The Network Codes should also address the issues of integration of any other new technology that could be beneficial and have an influence on System Operation.
