The Operation Handbook is divided into three parts:
- General part comprising the introduction and the glossary of terms
- Policies comprising technical criteria, requirements, standards, procedures and measures
- Appendices with technical description of the subject
It is recommended to start with the introduction document (I). Basic principles and frameworks for the complete handbook are described here in detail. Moreover, the introduction includes the full table of operation policies that are part of the handbook.
The glossary of terms (G) needs to be consulted as a reference only. All terms written in capitals can be found here. In case of unknown terms, acronyms or units please refer to this glossary for definitions and explanations.
For reading a policy (policies are numbered by #) it is recommended to start with the introduction of the policy and to consult the corresponding appendices (A#) before reading the requirements, standards and guidelines. The appendices usually give a general motivation and technical description of the subjects that is required for reading the policies.
The policies themselves (P#) are organised in independent chapters (starting with A), each of them in sections with numbered paragraphs. Before reading a policy it is necessary to have background knowledge on the subjects concerned. Internal references may point to other paragraphs of this policy before or after the current paragraph, external references may point to other policies or appendices as well.
Revision of Emergency Operations (Policy 5) of the Continental Europe Operation Handbook
What has been updated:
A new definition for total load. This definition will be used when TSOs design the schemes for disconnection of demand at low frequency level. The new definition takes into account the percentage of connected renewable energy sources with the overall objective to minimize the disconnection of generation connected to distribution systems.
In order to optimize performance of the demand disconnection scheme, the new definition of total load takes into account the percentage of renewable energy sources connected to distribution systems with the overall objective to guarantee that renewable generation units remain connected under a demand disconnection situation.
Detailed description of roles and responsibilities of TSOs in the restoration processes: this framework ensures coordination of national control centres and ensures efficient management of wide area emergency situations under challenging time constraints. Through these processes TSOs can bring the system back to the normal operating conditions and minimize the impact for consumers.
Updated TSO/DSO coordination framework: this framework addresses the importance of the TSO/DSO coordination in the management of emergency situations in the planning phase (design of defence plans ) as well as in the operational processes in real-time emergency situations.
