  • UKRENERGO CONCLUDES A SERVICE CONTRACT TO INVESTIGATE SYNCHRONOUS INTERCONNECTION OF IPS OF UKRAINE TO ENTSO-E

    Ukrenergo has signed a Service Contract with the ENTSO-E Consortium of TSOs to explore the possibility of synchronous operation of the Ukrainian grid with ENTSO-E. The contract envisages developing a common mathematical model of the Ukrainian grid and ENTSO-E and studying the grid’s dynamic and static stability. These studies are an integral part of the Agreement on the Conditions of Future Integration of the IPS of Ukraine into ENTSO-E.

    Preparations for the research started last summer, including developing test procedures, techniques and programmes and securing USAID funding. In January-April 2019, observers from the Ukraine/Moldova Project Group took part in tests of automatic frequency and power regulation and automatic control of generator excitation at 11 units of 8 power plants.

    Within the framework of the Service Contract, mathematical models of the power grid will be created based on the obtained test results and additional data to simulate its operation in different modes. This will allow to observe the response of the grid to different situations, to show how quickly it recovers when disturbances occur in the backbone network, etc.

    Findings of the analysis will allow to form the conclusions, which will serve as the basis for deciding on the possibility of synchronous integration of the IPS of Ukraine into ENTSO-E or highlight additional measures required.

    The €2.2 million study is to be funded by the World Bank loan under the Second power transmission project (PTP-2). The study is expected to be completed by the end of 2020.

    Similar studies will be conducted for the Ukraine/Moldova joint control block and will be conducted in the Moldovan power system under a separate contract between Moldelectrica IS and the Consortium.

    ENTSO-E Consortium of transmission system operators was created in April 2019 by decision of the Regional Group ENTSO-E Continental Europe. It includes TSOs in Germany, Poland, Slovakia, Hungary, Romania, Serbia.
