9. OPERATION OF THE UES OF RUSSIA |
|
In 2003, the AC frequency in the UES of Russia, the energy systems of the CIS and Baltic countries was maintained 100% of calendar time within the norms defined for the West European energy pool.
In 2003, the Unified Energy System demonstrated stable operation. The power companies delivered electricity to industries and households in Russia and fulfilled their contractual obligations for the supply of electricity to the former USSR republics and beyond. The systemic reliability of the UES of Russia in an increasingly competitive environment in the energy industry was ensured by the results of the reform in the operational dispatch management within the framework of preparation for the restructuring and liberalization of the electric power industry. The average AC frequency in the UES of Russia in 2003 was 50.00 Hz. The Unified Energy System of Russia operated at the standard electrical frequency prescribed by the Federal standard (GOST) 100% of calendar time. The efforts to improve the frequency control quality allowed the frequency within the energy pool of Russia, the CIS and Baltics to be maintained 100% of time in 2003 within the standard established by the West European energy pool, or UCTE (50.00±0.05 Hz). In 2003, the UES of Russia worked parallel with the energy systems of Azerbaijan, Belarus, Georgia, Kazakhstan, Latvia, Lithuania, Moldova, Mongolia, Ukraine, and Estonia. The energy systems of the Central Asia–Uzbekistan, Kirghizia, Turkmenistan, and Tajikistan,–operated in parallel with the UES of Russia through the energy system of Kazakhstan. Finland's energy system, which is part of the Nordic energy pool NORDEL, operated in parallel with the UES (via a DC link). Electricity from the UES power grid was supplied to some areas of Norway, China, Poland, and Turkey.
Organization of Dispatch Management
The key objective at the initial stage of the electric power industry reform is the restructuring of regional operational dispatch management by transferring these functions from regional energos to OAO "UES SO-CDA". By now the formation of the operational dispatch management hierarchy within OAO "UES SO-CDA" has been virtually completed. As at 31 December 2003, 58 regional energos transferred the performance of functions of regional operational dispatch management to OAO "UES SO-CDA". Another 10 regional energy system completed the transfer of the RDA functions to branches of the System operator in the first half of 2004. To complete the formation of a unified operational dispatch management system within the UES of Russia, it is necessary to transfer the functions of regional operational dispatch management from OAO "Komienergo", OAO "Tatenergo", OAO "Bashkirenergo", OAO "Novosibirskenergo", and OAO "Irkutskenergo" to OAO "UES SO-CDA". One of the most important means of maintaining the reliability and robustness of the UES of Russia is its multilevel system of anti-breakdown automatics unparalleled in the western energy pools. This system helps contain and prevent the expansion of system outages by:
The business process reengineering of operational dispatch management undertaken in 2003 ensured timely technological readiness of the System Operator for holding trading in the competitive segment of the wholesale electricity market. The System Operator carried out a comprehensive task of workflow automation which made it possible to start the transition to a competitive electricity market. With effect from 00:00 hours on 2 November 2003, the operational management of the UES of Russia is performed in an environment of coexistence of the competitive and regulated electric power market segments. It has been confirmed that the trading system, as well as the technological infrastructure are ready for the functioning of the competitive wholesale electricity market. Since 1 November 2003, there have been no breakdowns in the information management system of the power exchange. The integrated hardware and software of the System Operator is undergoing further development with the purpose of enhancing automation of business processes during the period of implementation of the transitional model for the wholesale electric power market. The System Operator is preparing to replace its SCADA/EMS information system with a system for the upper level purchased from the world-renowned suppliers. An order to develop the corresponding system for the SO-RDA level has been placed with a Russian development company. As the energy system entities do not have sufficient commercial metering facilities, one of the priorities in the preparation for the launch of a transitional wholesale electricity market was to create a temporary system of commercial metering. The day-ahead planning of the UES operation, as opposed to the three-days ahead schedules or more, makes it possible to use more up-to-date information reflecting the state of the principal equipment of power plants, electrical network topology, and consumption forecast. The better planning ultimately results in decrease of deviations of actual operation modes from the planned ones.
