Investigation of Influence of HTLS and Compact Design in Transmission Network Considering Transmission Capacity and Losses

Process of transmission planning needs to provide the location and type of solution that will ensure quality and security of supply network users. Taking into account the stated requirements, the transmission network (TN) must have satisfactory electricity transmission capacities (TC) and it is necessary to determine the technical solutions at an acceptable financial cost. In this paper, a model will be presented how to determine the location and type of investment, taking into account the connection of future power plants, users, development plans of neighbouring countries and the energy strategy of Europe. The model evaluates the possibilities of implementation of high-temperature low sag conductors (HTLS) and compacted overhead transmission lines (OHL) on the existing infrastructure or construction of new transmission lines in the same right of way. The main idea of the presented model is to investigate the influence of a proposed investment based on measurement data taking into account losses and TC of the TN as important factors. In order to increase TC taking into consideration TN losses, a number of possible technical solutions will be investigated.
