1.The requirements set out in this Chapter apply to the connection to the network of AC-connected power park modules located offshore. An AC-connected power park module located offshore which does not have an offshore connection point shall be considered as an onshore power park module and thus shall comply with the requirements governing power park modules situated onshore.
2.The offshore connection point of an AC-connected offshore power park module shall be specified by the relevant system operator.
3.AC-connected offshore power park modules within the scope of this Regulation shall be categorised in accordance with the following offshore grid connection system configurations:
(a)configuration 1: AC connection to a single onshore grid interconnection point whereby one or more offshore power park modules that are interconnected offshore to form an offshore AC system are connected to the onshore system;
(b)configuration 2: meshed AC connections whereby a number of offshore power park modules are interconnected offshore to form an offshore AC system and the offshore AC system is connected to the onshore system at two or more onshore grid interconnection points.
The frequency stability requirements laid down respectively in Article 13(1) to (5), except for Article 13(2)(b), Article 15(2) and Article 21(2) shall apply to any AC-connected offshore power park module.
1.Without prejudice to point (a) of Article 14(3) and point (a) of Article 16(3), an AC-connected offshore power park module shall be capable of staying connected to the network and operating within the ranges of the network voltage at the connection point, expressed by the voltage at the connection point related to reference 1 pu voltage, and for the time periods specified in Table 10.

| Synchronous area | Voltage range | Time period for operation |
|---|---|---|
| Great Britain | 0.90 pu – 1.10 pu where the voltage base for pu values is below 300kV | Unlimited |
| 0.90 pu – 1.05 pu where the voltage base for pu values is from 300kV to 400kV | Unlimited | |
| 1.05 pu – 1.10 pu where the voltage base for pu values is from 300kV to 400kv | 15 minutes] |
The table shows the minimum period during which an AC-connected offshore power park module must be capable of operating over different voltage ranges deviating from the reference 1 pu value without disconnecting.
4.The voltage stability requirements specified respectively in points (b) and (c) of Article 20(2) as well as in Article 21(3) shall apply to any AC-connected offshore power park module.
5.The reactive power capability at maximum capacity specified in point (b) of Article 21(3) shall apply to AC-connected offshore power park modules, except for Table 9. Instead, the requirements of Table 11 shall apply.
| Synchronous area | Maximum range of Q/Pmax | Maximum range of steady-state voltage level in PU |
|---|---|---|
| Great Britain | 0, at the offshore connection point for configuration 1 (as described in Article 23(3)(a)). | 0.225 |
| 0.33, at the offshore connection point for configuration 2 (as described in Article 23(3)(b)). | 0.225] |
