(b) the test 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. Simulated frequency deviation signals shall be injected to perform the test;

(c) the test shall be deemed successful if the following conditions are fulfilled:

(i)

the activation time of the full active power frequency response range as a result of a frequency step change is no longer than that required by point (d) of Article 15(2);

(ii)

undamped oscillations do not occur after the step change response;

(iii)

the initial delay is in line with point (d) of Article 15(2);

(iv)

the droop settings are available within the ranges specified in point (d) of Article 15(2) and the deadband (threshold) is not higher than the value chosen by the relevant TSO; and

(v)

the insensitivity of active power frequency response does not exceed the requirement set out in point (d) of Article 15(2).

5. With regard to the frequency restoration control test the following requirements shall apply:

(i)

operation in excess of 60 % of maximum capacity for 30 min;

(ii)

operation within the range of 30-50 % of maximum capacity for 30 min; and

(iii)

operation within the range of 10-20 % of maximum capacity for 60 min;

(c) the test shall be deemed successful if the following criteria are fulfilled:

(ii)

the power park module's capability to change to any reactive power target value within the agreed or decided reactive power range is demonstrated; and

(iii)

no protection action takes place within the operation limits specified by the reactive power capacity diagram.
