Trial Phase. A Trial Phase is only required for processes that have potential impact on system security. In case one or more TSOs submit a new process proposal every proposing TSO is obliged to perform an assessment on potential impact on system security. In case where system security impact is detrimental, RG CE or SOC (in case of inter-Synchronous Area impacts) shall decide whether a Trial Phase shall be performed. Trial Phase for Imbalance Netting, Cross-Border Activation of Reserves, Exchange of Reserves and Sharing of Reserves processes The relevant TSO involved in an Imbalance Netting Process, a cross-border aFRR Activation or mFRR Activation Process, a cross-border RR Activation Process, an exchange or sharing of Reserves between LFC Blocks within or between Synchronous Areas shall foresee a trial phase of at least one year. The Trial Phase shall include a regular reporting. The regular report shall be delivered each 6 months (or as otherwise agreed by SG CSO) and provided to the SG CSO with at least the statistical evaluation of ACE, cross-border power interchange, possible impact on the Frequency Quality as well as evaluation of operational procedures. The SG CSO shall decide about the successful completion of the Trial Phase based on the evaluations provided by the regular report. Trial Phase for Additional processes In case a Trial Phase for an Additional Process has been approved by the RG CE according to the Notification of Additional Processes, the SG CSO shall: report every three months to the RG CE evaluate the impact of the process on Operational Security at the end of the trial phase inform the RG CE about the final results and recommend a final decision to the RG CE. The RG CE shall decide on the implementation of the process. requirements concerning the availability, reliability and redundancy of the technical infrastructure according to Article 118(1)(p) SO GL (mandatory) Reliability The frequency restoration controller of aFRR shall be operated on-line and shall have a very high reliability. The tools for activation of mFRR and RR shall be operated on-line and shall have a very high reliability as well. A hot-stand-by-backup system must be available to take over the control function in case of an outage or fault of the main system. This requirement applies as well for all European platforms performing cross-border Imbalance Netting or a cross-border FRR and RR activation process. Reliability of Measurements Measurements must be transmitted in a reliable manner, i.e. redundant/parallel data links, to the frequency restoration controller. The used communication protocols must allow detecting invalid values and missing or invalid measurement values shall cause an alarm. For each LFC Area of Synchronous Area CE, the related TSO shall have frequency measurements from at least two different geographical locations available within this LFC Area. Redundancy TSO Control Rooms Redundancy The control room functions shall be backed up to face any damage to the main installations. This shall be activated within less than three hours and tested at least once a year. Manual Control Capability In case of deficiency of the automatic frequency restoration controller, manual control of reserves must be possible. Metering and Measurement Transmission to Opposite Side The operating TSOs of a tie-line shall agree on a common primary measurement, whose measured value shall be used in the load frequency controller of the concerned TSOs. A secondary measurement shall be used as backup and shall be available in parallel to the primary measurement in case the active power-flow can exceed 50 MW. Accuracy and cycle times for the secondary measurements must fulfil the same characteristics as the primary measurements. Availability Data Recording Each TSO of Synchronous Area CE shall perform continuous recordings with a measurement period equal to or shorter than 10 s of all values needed for monitoring of the input and response of the frequency restoration controller and for analysis of normal operation and incidents in the Synchronous Area. These values include: the frequency measurement, the total active power flow measurement and the power exchange set-point value. Sharing of information The TSO shall inform in real-time all TSOs within the Synchronous Area CE about its Wide Area State of the system. In case of not being in Normal State, the constrained TSO shall provide more details on critical operational conditions and at minimum to the interconnected TSOs, expected time to come back to Normal State and shall call for help if needed (refer to bi-multilateral TSOs agreements). The constrained TSO shall communicate the information via the following ways: EAS, preformatted messages (Fax, e-mail, web-based, etc.), phone calls to complement messages. Inter-TSO Contact lists for system operation Inter-TSO agreements shall include a list of functional positions directly involved in the system operation to be contacted at any time with phone numbers, fax numbers and e-mail addresses that shall be provided by all TSOs of the Synchronous Area CE and regularly updated. This list includes desks of control rooms and the relevant staff. All critical information about real-time operation shall be sent to these TSO counterparts. Common Rules for the Operation in Normal State and Alert State according to Article 118(1)(q) SO GL (mandatory)
