“…A database has been compiled based on all parameters of the lines and the measured data that are used to perform the calculations with the aid of the program. The program was developed by the staff of two Ostrava universities and has been published [13,14]. The calculations have been performed due to the need to verify the accuracy of software calculations and to clarify changes in the magnitude of losses with respect to atmospheric temperature movements and the line transmitted power in the area where network configuration changes have been made.…”

“…The specific area of the transmission system has been selected in view of the interesting states that can occur during its operation, especially greater variations of atmospheric temperatures and fluctuations of the transmitted power. [13][14][15] It is an area in which provision of an optimal power to the Horní Životice substation posed problems in previous periods. The capacity of the area has been reinforced by the construction of a new Kletná substation and by the erection Temperature and Transmitted Power of another V458 transmission line.…”

Innovations and trends has been significantly increased during modern theory and practical realizations in the field of energetic. In the Czech Republic, the research of predictions of technical losses on the transmission system can be considered as novel and important topic. Using software possibilities can be appropriately utilized in the frame of estimations of the technical losses. While they cannot be eliminated, they may be minimized. Losses can be measured or calculated using transmission-line parameters. This causality is considered in the form of the presented and proposed mathematical equations including real measured data of the atmospheric temperatures achieved on the substations selected in the Moravian-Silesian region. In this contribution, results of proposed calculations of technical losses based only on line parameters taking into account the ambient temperature are being compared in relation to a particular transmission system using prediction software. Particularly, technical losses caused by a configuration change of a selected part of a transmission system are considered related to the operation of Dlouhé Stráně pumped storage hydro power plant. As can be conclude, after the resulted comparisons using by the proposed mathematical models in software and the obtained real measured data, general minimization of the losses is necessary to create the most accurate models of the states that might occur in the future and to propose required modifications of the given part of the transmission system. A future bounded research can be focused on the sensors situated on the transmission lines instead of the substations.

The rise in power demands and concern over climate change is leading to increased penetration of wind energy into the grid. However, the transmission network infrastructure is not equipped for such a transition. Transmission lines are responsible for the transfer of electric power from generating stations to load centres and consumers. In this process, the lines incur losses which affect the quality of power. Also, it has an economic impact on the utilities. Therefore, such losses must be minimised so that the power quality can be improved and economic losses are less. With the increase in the percentage of wind energy integration in the grid, the transmission line losses are increasing. To address this problem, a remedial action scheme (RAS) has been proposed for increasing wind energy penetration in the grid with minimum transmission line losses. To achieve this, the proposed method uses a multiobjective optimisation problem which is solved using the genetic algorithm. For varying transmission line losses, the multi-objective optimisation problem determines the optimal generation from each wind generator. The proposed RAS is tested for the New England 39-bus network and the results highlight the performance of the method to maximise the wind power injection.
