Serbia Power System Study: Power system generation, network plan and modelling (Phase 1)

Identification of total system costs for the existing renewable development scenario with the aim to identify tariff impact caused by renewable integration.

In the Phase 1, analytical work encompassing modelling of the power system at generation and network level and the identification of needed investment to support RE going forward.

Generation analysis identifies yearly operational costs, export & import volumes and CO2 emission in year 2020, 2025 and 2030 through generation simulations, based on official generation development plans, average hydrology and average RES generation hourly profiles. Network analysis (load flow and short circuit studies) are focused on 400, 220, and 110 kV networks for winter peak and summer off peak on the year 2020, 2025, and 2030 with the aim to analyze obstacles in transmission network of Serbia and to propose necessary reinforcements to meet forecast demand and planned generation development. These analyses help in assessment of technical challenges of integrating RES shares of the government targets at various stages of development (2020, 2025 and 2030) and identification of solutions and associated costs for the analyzed base case scenario.

Type of services provided:

• Modeling of the power system elements in GTMax
• Simulations and determination of total costs, prices, exchanges and emissions in 2020, 2025 and 2030 year
• Transmission network modeling
• Simulations (load flow/short circuit) in characteristic hours (winter max and summer min) in 2020, 2025 i 2030 year and identification of constraints related to RES integration
• Identification of solutions and associated costs
