TITLE IVU.K. COMPLIANCE

CHAPTER 6 U.K. Compliance simulations for power park modules

Article 55U.K.Compliance simulations for type C power park modules

1.In addition to the compliance simulations for type B power park modules set out in Article 54, type C power park modules are subject to the compliance simulations set out in paragraphs 2 to 7. Instead of all or part of those simulations, the power-generating facility owner may use equipment certificates issued by an authorised certifier, which must be provided to the relevant system operator.

2.With regard to the LFSM-U response simulation the following requirements shall apply:

(a)the power park module's capability to modulate active power at low frequencies in accordance with point (c) of Article 15(2) shall be demonstrated;

(b)the simulation shall be carried out by simulating low frequency steps and ramps reaching maximum capacity, taking into account the droop settings and the deadband;

(c)the simulation shall be deemed successful in the event that:

(i)

the simulation model of the power park module is validated against the compliance test for LFSM-U response set out in Article 48(3); and

(ii)

compliance with the requirement laid down in point (c) of Article 15(2) is demonstrated.

3.With regard to the FSM response simulation the following requirements shall apply:

(a)the power park module's capability to modulate active power over the full frequency range as referred to in point (d) of Article 15(2) shall be demonstrated;

(b)the simulation shall be carried out by simulating frequency steps and ramps big enough to trigger the whole active power frequency response range, taking into account the droop settings and the deadband;

(c)the simulation shall be deemed successful in the event that:

(i)

the simulation model of the power park module is validated against the compliance test for FSM response set out in Article 48(4); and

(ii)

compliance with the requirement laid down in point (d) of Article 15(2) is demonstrated.

4.With regard to the island operation simulation, the following requirements shall apply:

(a)the power park module's performance during island operation in accordance with the conditions set out in point (b) of Article 15(5) shall be demonstrated;

(b)the simulation shall be deemed successful in the event that the power park module reduces or increases the active power output from its previous operating point to any new operating point, within the P-Q-capability diagram and within the limits set out in point (b) of Article 15(5), without disconnection of the power park module from the island due to over- or underfrequency.

5.With regard to the simulation of the capability of providing synthetic inertia, the following requirements shall apply:

(a)the model of the power park module's capability of providing synthetic inertia to a low frequency event as set out in point (a) of Article 21(2) shall be demonstrated;

(b)the simulation shall be deemed successful if the model demonstrates that it complies with the conditions set out in Article 21(2).

6.With regard to the reactive power capability simulation, the following requirements shall apply:

(a)the power park module shall demonstrate that it can provide leading and lagging reactive power capability as set out in points (b) and (c) of Article 21(3);

(b)the simulation shall be deemed successful if the following conditions are cumulatively fulfilled:

(i)

the simulation model of the power park module is validated against the compliance tests for reactive power capability set out in paragraph 6 of Article 48; and

(ii)

compliance with the requirements laid down in points (b) and (c) of Article 21(3) is demonstrated.

7.With regard to the power oscillations damping control simulation, the following requirements shall apply:

(a)the model of the power park module shall demonstrate that it can provide active power oscillations damping capability accordance with point (f) of Article 21(3);

(b)the simulation shall be deemed successful in the event that the model demonstrates compliance with the conditions described in point (f) of Article 21(3).
