Prediction of latvian electrical power system for reliability evaluation including wind energy

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 for finding of EPS options, which are most weak to outer impacts, identify their relations with the EPS parameters, use this data for enhancement of power system behavioural properties. Thus, accessibility of data on the location of weak spot allows identify and control nodes, in which the biggest oscillations of operational parameters are observed due to perturbations in the network.
