Black Sea Regional Transmission System Planning Project (BSTP): Analysis of the Potential to Provide Cross-Border Balancing Reserves and Energy in the Black Sea Region; PSS/E NTC Calculation Workshop; Workshop on Modelling HVDC

Whole project consists of three parts (one study and two workshops) with the following objectives:

• Analysis of the Potential to Provide Cross-Border Balancing Reserves and Energy in the Black Sea Region:
• Building on the results of the Phase I: Impact Assessment of Regional Balancing Integration in the BSTP Electricity Market Study completed in 2016, the objective of Phase II is to describe possible options, constraints and risks to integrating balancing markets in the Black Sea region, as well as to estimate the potential benefits from common use of balancing capacities and energy.
• The analytical focus will be on Secondary and Tertiary control (both Automatic and Manual Frequency Restoration (aFRR/mFRR) and Replacement Reserve (RR), i.e. Slow Tertiary control), as there are several potential options for integrating the provision of these reserves or a sub-regional basis, including:
• Applying imbalance netting to minimize counteracting activation of balancing energy;
• Integrating individual merit order lists for balancing energy into one common merit order list and;
• Cooperation for balancing capacity.
• PSS/E NTC Calculation Workshop/Preparation for Joint BSTP/BSRI Workshop:
• ENTSO-E Net Transfer Capacity (NTC) Calculation Methodologies;
• BSTP PSS/E NTC Calculation Simulation Model update with explanations and practical calculation examples in the BSTP region.
• Workshop on Modelling High Voltage Direct Current (HVDC) Converter Stations and BSTP Models Update:
• This Workshop with corresponding process of regional model upgrading discusses the most important types of analysis that are necessary for the planning of HVDC based networks, addressing the simulation models which are recommended for each of these studies. The focus is on steady state and dynamic stability simulation analyses which are supported by regional BSTP PSS/E planning models for 2020 and 2025 (winter max, summer max and summer min regimes).

Type of services provided:
