Article 20 U.K. Requirements for type B power park modules

1. Type B power park modules shall fulfil the requirements laid down in Articles 13, except for Article 13(2)(b), and Article 14.

2. Type B power park modules shall fulfil the following additional requirements in relation to voltage stability:

(a) with regard to reactive power capability, the relevant system operator shall have the right to specify the capability of a power park module to provide reactive power;

(b) the relevant system operator in coordination with the relevant TSO shall have the right to specify that a power park module be capable of providing fast fault current at the connection point in case of symmetrical (3-phase) faults, under the following conditions:

(i)

the power park module shall be capable of activating the supply of fast fault current either by:

• ensuring the supply of the fast fault current at the connection point, or

• measuring voltage deviations at the terminals of the individual units of the power park module and providing a fast fault current at the terminals of these units;

(ii)

the relevant system operator in coordination with the relevant TSO shall specify:

• how and when a voltage deviation is to be determined as well as the end of the voltage deviation,

• the characteristics of the fast fault current, including the time domain for measuring the voltage deviation and fast fault current, for which current and voltage may be measured differently from the method specified in Article 2,

• the timing and accuracy of the fast fault current, which may include several stages during a fault and after its clearance;

(c) with regard to the supply of fast fault current in case of asymmetrical (1-phase or 2-phase) faults, the relevant system operator in coordination with the relevant TSO shall have the right to specify a requirement for asymmetrical current injection.

3. Type B power park modules shall fulfil the following additional requirements in relation to robustness:

(a) the relevant TSO shall specify the post-fault active power recovery that the power park module is capable of providing and shall specify:

(i)

when the post-fault active power recovery begins, based on a voltage criterion;

(ii)

a maximum allowed time for active power recovery; and

(iii)

a magnitude and accuracy for active power recovery;

(b) the specifications shall be in accordance with the following principles:

(i)

interdependency between fast fault current requirements according to points (b) and (c) of paragraph 2 and active power recovery;

(ii)

dependence between active power recovery times and duration of voltage deviations;

(iii)

a specified limit of the maximum allowed time for active power recovery;

(iv)

adequacy between the level of voltage recovery and the minimum magnitude for active power recovery; and

(v)

adequate damping of active power oscillations.
