Energy is one of the sectors directly affecting the economic growth and forming a significant part of overall expenses in several industry branches, especially in manufacturing. The development of the energy sector requires significant investments which can only be attracted in a stable and predictable investment environment. Therefore, Latvian energy sector is being planned in a long-term both globally...
Within the last two decades, increase in electricity demand and environmental concern resulted in fast growth of power production from renewable sources. Wind power is one of the most efficient alternatives. Therefore, the issue on integration of a new renewable power plant into the existing electrical power system(EPS) is the topical terms of stability. The goal of this paper is to ensure approach...
Due to the advances in photovoltaic material research and solar panel price reduction over last years, the usage of this alternative energy source in northern countries seems more attractive. Usage of energy storage devices can help use the solar power more efficiently and smarter. This paper deals with the optimization of proposed solar panel array of renovated office building's communal lighting...
The electric power system (EPS) is exposed to small and large impacts during operation, such as changes of loads, commutation of circuit elements, changes of generation of active and reactive power, the impact of automation, (all of them are examples of normal relatively small disturbances), as well as short circuits, large load resets and load surge, unauthorized shutdown of equipment, work of protections...

Electric Power System (EPS) is continuously subjected to internal and external disturbances that cause changes in the operational parameters — the EPS response. Change in parameters depends on the type and magnitude of the disturbance, its application point (external factors), and the diagram and parameters of EPS elements (internal factors). The purpose of this paper is to provide methods for detection...
The market economy dictates the terms of unification of the energy systems of the countries that leads to a change in number of interconnections, the increase of the transmitted power, and therefore, it is necessary to reconfigure the networks and, consequently, the recalculation of their normal modes, as well as the project assessment of static stability is required. Stability is an important constraint...
