Power Park Modules (PPM)

Guidance Documents

Documents relating to controllability, categorisation, and certification are listed below, along with Technical specification documents which are published regularly.  

This TSO & DSO Wind Farm Testing Protocol sets out the agreed approach between the TSO and the DSO in relation to Distribution Code Compliance Testing process for Controllable Power Park Modules with a registered capacity of 5MW or more.

Power Park Module Updates or Testing

Power Park Modules must submit a PPM Load Profile Request Form before making any changes to Power Park Module characteristics, software upgrades or before carrying out any testing that is not scheduled with us.

PPM On-site testing

All TSO and DSO connected PPMs must carry out a site survey in coordination with on site EirGrid personnel.

TSO connected PPMs must carry out a black start shutdown test in coordination with on site EirGrid personnel and NCC personnel.

For DSO connected PPMs must carry out a Dispatch Fail test in coordination with EirGrid and DSO. Please refer to DSO for DFT template.

Note there is no operational requirement for Black Start Shutdown scheme for Battery Energy Storage Power Stations. For hybrid sites e.g. WFPS and Battery, Black Start Shutdown will be required due to the presence of the WFPS. This requirement extends to Dispatch Fail Lamp (DFL) and Blue Alert Lamp (BAL) for distribution connected batteries.

PPM Site Survey Procedure

 Black Start Shutdown Test Procedure

EirGrid Grid Code version 8 has been updated in accordance with the European Network Requirements for Generators (RfG). Generators will now be categorised as RfG or Non-RfG under the Grid Code (references below).

Battery Energy Storage Power Stations (ESPS) are considered non-RfG units.

A Generation Unit with a signed Connection Agreement:

a) Connected to the Network on or before the 30th November 2018; or

b) Whose owner has concluded a final and binding contract for the purchase of the main Plant on or before the 30th November 2018 and provides evidence of same, as acknowledged by the TSO, on or before the 31st May 2019. Such evidence shall at least contain the contract title, its date of signature and date of entry into force, and the specifications of the main Plant to be constructed, assembled, or purchased; or

c) Is one of the exceptions to the applicability of the New Generation Unit requirements and is a Generation Unit as follows:

(i) Installed to provide back-up power and operate in parallel with the Network for less than five minutes per calendar month while the system is in  normal system state; or

(ii) No permanent Connection Point and is used by the TSO to temporarily provide power when normal system capacity is partly or completely unavailable; or

(iii) Energy Storage Units except for Pumped Storage Plant.

An Existing Generation Unit that undergoes a substantial modification to its Connection Agreement and concludes a final and binding contract for the purchase of the Plant being modified after the 30th November 2018 will be deemed a New Generation Unit, unless the Plant being modified is one of the exceptions listed in c) above.

Windfarm Signal Lists

EirGrid issues a signal list for each controllable wind farm. Templates are published here for different types of wind farms: Signal List Template TSO, Signal List Template DSO Topology 1, Signal List Template DSO Topology 2 and Signal List Template DSO Topology 3, 4 and 5. These templates include a list of information the wind farm must provide for EirGrid to develop a site-specific signal list, to include Control System Parameters.

Note 1. For multiple market units: there shall be one set of Voltage related signals/measurands per connection point. There shall be one set of all other signals/measurands per market unit.
Note 2. The signal list templates now include a tab specifying how signals shall function or be calculated.

Grid Code Compliance Testing
The Schedule of Tests is a list of all tests that a Power Park Module must complete to achieve an Operational Certificate. These tests are divided into phase A (up to energisation), phase B (up to operational readiness) and phase C (up to operational certificate). A template procedure for each test in phase C and a corresponding PPM Grid Code Compliance Test Report to help with the tests are published in the table below. A workbook Test report workbook is also published to help with calculations in the report.

The Schedule of Tests is a list of all tests that a Power Park Module must complete to achieve an Operational Certificate. These tests are divided into phase A (EON) (up to energisation), phase B (ION) (up to operational readiness) and phase C (FON) (up to operational certificate). A template procedure for each test in phase C and a corresponding PPM Grid Code Compliance Test Report to help with the tests are published in the table below. A workbook Test report workbook is also published to help with calculations in the report.

Battery Energy Storage Power Stations (ESPS) are classified as PPMs in the EirGrid and SONI Grid Codes. Battery ESPS with a registered capacity greater than 1 MW (EirGrid) / 5 MW (SONI) must be controllable and dispatchable.

An implementation note for integration of Battery ESPS is linked here.

 

Battery ESPS Signal Lists

EirGrid issues a signal list for each controllable battery unit. Templates signal lists will be published in future.

Note 1. For multiple market units: there shall be one set of Voltage related signals/measurands per connection point. There shall be one set of all other signals/measurands per market unit.
Note 2. The signal list templates shall include a tab specifying how signals shall function or be calculated.
