The study addressed both how electricity markets and prices will be affected by substantial amounts of RES development, and how the transmission grid will need to adapt – both within the BSTP countries and between them – as RES becomes a more significant share of the generation mix by 2030.

The impact of large-scale RES integration on market operation has been analysed using the Antares software tool. This analysis enabled the BSTP members to assess the impact of large-scale RES integration on wholesale market prices, country balances, cross-border flows and congestion costs.

The PSS/E software tool has been used to analyze the impact of large-scale RES integration on the grid. This analysis enabled BSTP members to better understand the effects of large-scale RES integration impact on load flows, voltage profiles, secure grid operations and congestion in the regional transmission network. The Consultant ran the models sequentially, first determining the market results for large-scale RES development under selected scenarios. Thereafter, the Consultant analyzed whether the results are consistent with a robust and reliable network.

In support of the study, the Consultant conducted three capacity building workshops over the course of 2020 activities, focusing on the following topics:

  • RES Integration Capacity Building Workshop
  • Advanced Antares Workshop
  • Capacity Calculation and Congestion Management Workshop.

Type of services provided:

  • Development of the BSTP power systems model in Antares sw tool
  • Analyses of the system operation in 2030 in different RES Scenarios
  • Implementation of the MonteCarlo simulations for different climatic, hydrological and thermal availability conditions
  • Calculation of system operation indicators
  • Selection of the relevant operating regimes for grid analyses
  • BSTP regional transmission network model update
  • Load flow calculations and voltage profiles assessment
  • Network loading and security analyses
