The relevant system operator has sole discretion to decide about its participation.
1.Simulation of the performance of HVDC systems and DC-connected power park modules shall aim at demonstrating that the requirements of this Regulation have been fulfilled.
2.Notwithstanding the minimum requirements set out in this Regulation for compliance simulation, the relevant system operator may:
(a)allow the HVDC system owner or DC-connected power park module owner to carry out an alternative set of simulations, provided that those simulations are efficient and suffice to demonstrate that a HVDC system or DC-connected power park module complies with the requirements of this Regulation or with national legislation; and
(b)require the HVDC system owner or DC-connected power park module owner to carry out additional or alternative sets of simulations in those cases where the information supplied to the relevant system operator in relation to compliance simulation under the provisions of Chapter 3 of Title VI, is not sufficient to demonstrate compliance with the requirements of this Regulation.
3.To demonstrate compliance with the requirements of this Regulation, the HVDC system owner and DC-connected power park module owner shall provide a report with the simulation results. The HVDC system owner and DC-connected power park module owner shall produce and provide a validated simulation model for a given HVDC system or DC-connected power park module. The scope of the simulation models is set out in Articles 38 and 54.
4.The relevant system operator shall have the right to check that a HVDC system and DC-connected power park module complies with the requirements of this Regulation by carrying out its own compliance simulations based on the provided simulation reports, simulation models and compliance test measurements.
5.The relevant system operator shall provide the HVDC system owner or DC-connected power park module owner with technical data and a simulation model of the network, to the extent necessary to carry out the requested simulations in accordance with Chapter 3 of Title VI.
1.The HVDC system owner shall ensure that the HVDC system and HVDC converter stations are compliant with the requirements provided for by this Regulation. This compliance shall be maintained throughout the lifetime of the facility.
2.The DC-connected power park module owner shall ensure that the DC-connected power park module is compliant with the requirements under this Regulation. This compliance shall be maintained throughout the lifetime of the facility.
3.Planned modifications of the technical capabilities of the HVDC system, HVDC converter station or DC-connected power park module with possible impact on its compliance to the requirements under this Regulation shall be notified to the relevant system operator by the HVDC system owner or DC-connected power park module owner before initiating such modification.
4.Any operational incidents or failures of an HVDC system, HVDC converter station or DC-connected power park module that have impact on its compliance to the requirements of this Regulation shall be notified to the relevant system operator by the HVDC system owner or DC-connected power park module owner as soon as possible without any delay after the occurrence of such an incident.
5.Any foreseen test schedules and procedures to verify compliance of an HVDC system, HVDC converter station or DC-connected power park module with the requirements of this Regulation shall be notified to the relevant system operator by the HVDC system owner or DC-connected power park module owner in due time and prior to their launch and shall be approved by the relevant system operator.
6.The relevant system operator shall be facilitated to participate in such tests and may record the performance of the HVDC systems, HVDC converter stations or DC-connected power park modules.
1.The relevant system operator shall assess the compliance of an HVDC system, HVDC converter station and DC-connected power park module with the requirements under this Regulation throughout the lifetime of the HVDC system, HVDC converter station or DC-connected power park module. The HVDC system owner or DC-connected power park module owner shall be informed of the outcome of this assessment.
2.Where requested by the relevant system operator, the HVDC system owner or DC-connected power park module owner shall carry out compliance tests and simulations, not only during the operational notification procedures according to Title V, but repeatedly throughout the lifetime of the HVDC system, HVDC converter station or DC-connected power park module according to a plan or general scheme for repeated tests and specified simulations or after any failure, modification or replacement of any equipment that may have impact on the compliance with the requirements under this Regulation. The HVDC system owner or DC-connected power park module owner shall be informed of the outcome of these compliance tests and simulations.
3.The relevant system operator shall make publicly available the list of information and documents to be provided as well as the requirements to be fulfilled by the HVDC system owner or DC-connected power park module owner in the frame of the compliance process. Such list shall cover at least the following information, documents and requirements:
(a)all documentation and certificates to be provided by the HVDC system owner or DC-connected power park module owner;
(b)details of the technical data of the HVDC system, HVDC converter station or DC-connected power park module with relevance to the grid connection;
(c)requirements for models for steady-state and dynamic system studies;
(d)timeline for the provision of system data required to perform the studies;
(e)studies by the HVDC system owner or DC-connected power park module owner to demonstrate the expected steady-state and dynamic performance in accordance with the requirements set out in Titles II, III and IV;
(f)conditions and procedures including the scope for registering equipment certificates; and
(g)conditions and procedures for use of relevant equipment certificates, issued by an authorised certifier, by the DC-connected power park module owner.
4.The relevant system operator shall make publicly available the allocation of responsibilities to the HVDC system owner or DC-connected power park module owner and to the system operator for compliance testing, simulation and monitoring.
5.The relevant system operator may partially or totally assign the performance of its compliance monitoring to third parties. In this case, the relevant system operator shall ensure compliance with Article 10 by appropriate confidentiality commitments with the assignee.
6.The relevant system operator shall not unreasonably withhold any operational notification in accordance with Title V, if compliance tests or simulations cannot be performed as agreed between the relevant system operator and the HVDC system owner or DC-connected power park module owner due to reasons which are in the sole control of the relevant system operator.
7.The relevant system operator shall provide the relevant TSO when requested the compliance test and simulation results referred to in this Chapter.
