Method of transmission power networks reliability estimation

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, which will use power network modernization and development. One of these methods is developed and examined in this paper. This reliability problems, which is devote modern, scientific and economic power system planning criteria and this calculation methods, review and assessment, is very actual.

Power network system reliability and methods of calculation

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 of electric national network to the international grid. In order to prevent similar problems in a future it is necessary to elaborate new methods of power supply reliability assessment, which will use power network modernization and development. One of these methods is developed and examined in this paper. This reliability problems, which is devote modern, scientific and economic power system planning criteria and this calculation methods, review and assessment, is very actual.

Optimization Method of Power System Development under Uncertainty

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 are formed by joining gradually network objects. In comparison with previous software systems of LDM family, the new systems have considerably simplified input and this considerably diminishes error probability

Integration of distributed generation in the networks of Latvian power system

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 analysed: hydro, wind and co-generation plants in Western electric distribution network of the Latvian power system (WEN). The results of the research are of essential significance and not only for Latvia but in general for any analogue power system.

Consistency Analysis and Data Consultation of Gas System of Gas-Electricity Network of Latvia

Abstract In the present research, the main critical points of gas transmission and storage system of Latvia have been determined to ensure secure and reliable gas supply among the Baltic States to fulfil the core objectives of the EU energy policies. Technical data of critical points of the gas transmission and storage system of Latvia have been collected and analysed with the SWOT method and solutions have been provided to increase the reliability of the regional natural gas system.

Distribution Cert projects - New approach for multinational network electricians qualification

Finland and Baltic States initiated Distribution Cert project realization, based on multifunctional professional educational system of Finland. Projects provide opportunities to harmonize Baltic vocational training (VET) systems with EU requirements and best Nordic practices. There is a practical working example of mutually beneficial collaboration between policymakers, employers and training service providers in Electricity sector. Efficient strategies of competence based qualifications and apprenticeship training systems, reducing repair duration and improving interruptions causes indices of human factors, installation quality, weather, maintenance and repairing quality.
