Ukraine Power System Support Project (UPSS): Winter 2014/2015 Ukraine Power System Analysis (Phase I)

The Ukraine Power System Support (UPSS) Project was established in September 2014 to investigate the technical potential of the regional high voltage networks ability to support and strengthen transmission network reliability in Ukraine. The project comprises of an emergency network study that assesses the stability of the high voltage transmission network in response to curtailed gas and coal fueled electric power generation coupled with expected increased demand for electricity resulting from consumers switching to electric heat. The UPSS Project is sub-regional to the Black Sea Regional Transmission Planning Project (BSTP) and supports USAID’s goals of: strengthening the interconnections of the Ukrainian power system, enhancing energy security and optimizing the generation fleet.

This project consider the development of different scenarios related to curtailment of gas and coal fuelled generation capacity as well as development of scenarios related to expected increases in electricity consumption.

The main objectives of the Project are to:

• investigate the current status of the Ukrainian transmission network, including damaged transmission elements in the Eastern part of the country;
• agree to assumptions regarding neighboring power system equivalents, basic national electricity consumption levels for the winter season and the availability of power plants and coal mines;
• taking into account the above assumptions, develop a set of indicative scenarios to include: potential support from other regional networks, re-allocation of coal resources, the production of generation plants; and
• propose appropriate recommendations for remedial actions based on standard static analysis by taking into account network limitations imposed on the system resulting from generation curtailment and increased load.

Type of services provided:

• Creation of simulation models for the scenarios
• Load Flow analysis with network element loadings for non-contingency status
• Voltage profile analysis of transmission network for non-contingency status
• Contingency analysis (N-1)
• Recommendations for remedial actions
• Providing ongoing technical support to Ukrenergo (Ukrainian TSO) to modify and run models and analyze various scenarios as contingencies arise.
