Black Sea Regional Transmission System Planning Project (BSTP) - Optimal Power Flow Sensitivity and Network Analysis
client: USEA, USAID
type: Study (Transmission, Market)
finishing date: September 2013
team: Milos Stojkovic – Project Manager, S. Mijailovic – Consultant and Coordinator, N. Jovic, T. Martinovic, D. Vlaisavljevic
Objective of this study is to collect national inputs and the development plans for further update of regional transmission model that will be used for power transmission system analysis for 2015 and 2020, thus promoting regional cooperation in transmission planning among Black Sea region TSOs.
This phase of the project was focused on performing further Sensitivity Analyses utilizing the regional OPF model in order to indicate potential features of electricity market development within Black Sea region. This phase of the project focused on performing further Sensitivity Analyses utilizing the regional OPF model in order to indicate potential features of electricity market development within Black Sea region. The goal of this analysis was to evaluate planned transmission network capacities for the analyzed period as well as possibilities for their further development throughout the asynchronous/synchronous integration of the whole region. In order to understand the sensitivity of obtained results to the input data assumptions, the Sensitivity Analysis determined which assumptions significantly impact the OPF results. In addition to the analysis, the existing OPF models was updated and validated to identify which economic factors have an influence on the model and the electricity market behaviour.
