Power supply reliability is one of the main criteria in estimation of power system networks. The decisions on radical changes in branch of electric power control and trade are still caused by essential monopolization, then reasoned with politicians, public, economic and technical factors and not less with international influence followed by ascendance to international alliances and wherewith connection...
Power supply reliability is one of the main criteria in estimation of power system networks. There have been many power system blackouts during the last years, which have resulted interruption in power supply and big material loses in many countries all over the world. In order to prevent similar problems in a future it is necessary to elaborate new methods of power supply reliability assessment,...
The risk assessment method for power system standard evaluation in regard to generation and transmission capacities adequacy for the perspective 5 and 10 years period under the information uncertainly conditions is being analysed in the paper. The tool of the method is the programme LDM-T&G'05 (Latvian Dynamic Model for Transmission and Generation). The programme provides the opportunity to perform...
Paper presents optimization method of power system development under uncertainty. Method is used for LDM family. Laboratory of Electric Power System Simulation worked out software of Latvian dynamic model (LDM) family. All softwares of LDM family ensure possibilities: 1) to eliminate investments, which increase prime cost, 2) to arrange the required investments by their efficiency. The databases LDM...
Distributed (dispersed) generation (DG) entities are private and operated independently upon the main grid in Latvia. In the paper the impact of connected DG to the distribution network is analysed in regard to network operation modes and network operation parameters: voltage losses, power flows and overflows, energy losses per year etc. As research objects private electric power plants have been...
