On May 8 and 9, at Zaporizhzhya NPP, specialists of SE NNEGC Energoatom and PJSC NPC Ukrenergo carried out tests of the power unit for ancillary frequency maintenance reserve services provision to the transmission system operator in the amount of +/- 20 MW, the press service reports.
The tests should confirm the compliance of ZNPP power unit 1 with the requirements of the Transmission System Code in order to obtain a certificate entitling Energoatom to introduce the power unit to the ancillary services market.
This is a crucial stage of the Unified power system of Ukraine preparation for integration with the Unified European continental power system.
Upon processing the test results, the conformity assessment body will make a technical report regarding the unit’s capacity to provide ancillary services. The next stage is obtaining a certificate by ZNPP unit No.1 and putting it on the Register of ancillary service providers, following which Energoatom will be able to enter the ancillary services market.
As a reminder, on April 16-17 similar tests were carried out at ZNPP power unit No.2. Furthermore, formerly NPC Ukrenergo researched generator excitation and load-frequency control systems of domestic NPPs. The test results are used by specialists to create a mathematical model of the Unified power system of Ukraine.
