- Abstract
The specific character of Latvian power system is the factor, that nearly 70% of all primary energy sources are imported, as well as 50% of all consumed electric power. Power deficit is covered by the import from the border countries - Lithuania, Estonia and Russia. That's why the question of Latvian power independence and external power supply, increase is very actual. It is also important to form free electric power market in Baltic states and to integrate it into the electric power market of European Union in the future. In the Latvian government basic positions on Latvian power industry development there is pointed out, that in the year 2012 Latvian power system must achieve 80% of self-provision on electric power, but in the year 2016 this level should be 100%. After Ignalina APP shutdown in 2010 it will be necessary to cut down import of electric power from Russia. Otherwise durable overload regimes in the transmission networks of neighboring counties may take place. Also additional problems may occur in those country system operators' synchronous operation. On electric power deficit in the country also influence unforeseen stoppage and unpredictable operation of aging devices on power plants in Narva (Estonia) and Kaliningrad TPP. The problem may be resolved by transmission networks and power generation development. Simultaneously it is necessary imported power sources diversification. As a perspective solution is offered opportunity to build power connection between Latvia and Sweden using sea cable in Baltic Sea. For the electrical connection with Sweden the best place in Latvia is Kurzeme region (town Ventspils). This variant complies with the minimal cable line length. If it will be made a decision to build cable line between Sweden and Latvia, than it is necessary to build 330 kV transmission line from Grobina to Ventspils and further to Riga. Also cable line Ventspils Parnu over the Gulf of Riga is needed. Without those lines it is not possible to buy, and sell electric power. In the work there are looked out three 330 kV network development strategies in Kurzeme region and coal power plant location variants Technologically-economical analyze is made using decision making theory in uncertainty condition and problem's multicriterion nature. Inspected criterions are thrown together into one criterion that determines economical efficiency of development plan. To chose the optimal strategy of highvoltage network development in Kurzeme region in Latvia was used Vald minimax criterion, that is oriented on the worst perspective plan realization perspectives and gives secure success with minimal risk. The gotten results of Latvian power system development in Kurzeme region optimization may be used as additional acknowledgment of accepted by Latvian government plans to build coal power plant in Liepaja.
