Application Form Part A EUROPEAN COMMISSION CONNECTING EUROPE FACILITY ENERGY A1 TENtec proposal number General Information on the Proposed Action Call for proposals CEF-Energy-2017 ▼ Call priority Not applicable ▼ Call sub-priority Not applicable Title of the proposed Action Study on Dynamic behaviour of synchronously interconnected Baltic States and continental European electricity network (via Poland), including preparatory works for application request to ENTSO-e for extension of synchronous area Proposal type Study▼ Start date of the proposed Action 29/09/2017 End date of the proposed Action 01/06/2018 Scope and objectives of the proposed Action (up to 2000 characters) The Study (Action), contributes to implementation of the Project of Common Interest “Various aspects of the integration of the Baltic States’ electricity network into the continental European network (CEN), including their synchronous operation” (Generic Project). The experience of extension of Continental Europe (CE) synchronous area has shown that power system dynamic and transient stability is one of the major limiting factors, in other words power flows from peripheral areas and inter-area oscillations can provoke instability of the interconnected power system operation, so the proposed Action is crucial for evaluation of feasibility of extension of CE synchronous zone in terms of stability phenomena, taking into account identification of necessary measures facilitating the Baltic States’ system synchronization process. The Action scope consists of: model preparation, verification and validation of both Baltic and CE models as well as adjustment of model parameters to their expected behavior in the interconnected system; transient stability and small signal stability analysis for selected scenarios to determine potential risks for interconnected power system operation, analysis of the Baltic power system connection impact on the CE system critical inter-area oscillations; analysis of the obtained results will enable to determine potential small signal stability risks for interconnected operation; recommendations and measures. The result of this Action is planned to be as a final step and important input to an application for catalogue of measures for synchronous interconnection of the Baltic power system with the CE power system via Poland to the respective bodies of ENTSO-E, namely to the Continental Europe Regional Group. Polish TSO will be directly involved in the preparation of the dynamic study On 29 th September Lithuania, Latvia, Estonia and Poland TSOs held a kick off meeting and took a common decision to perform a common dynamic study.
