Evaluation of possibilities for connection of wind farm Drahany 45 MW to 110 kV network
Gregr, Tomáš ; Opat, Jaroslav (referee) ; Topolánek, David (advisor)
This Master's thesis is focused on connecting of new power sources into electrical network, particularly, the steady state and allowed voltage variation in network nodes, which occur in steady state before and after connection of a new power source into distribution network, with regard to valid legislation. The new power source in question is the new wind farm Drahany with active power of 45 MW, which should be connected into distribution network 110kV, operated by distribution company E.ON. The aim of this work is to find the most suitable connection point of a wind farm into distribution network, considering transmission capacity of individual electric lines and voltage variations in network nodes, as well as Drahany wind farm's investor's expenses on construction of a connection line to connection point and the distribution network's operator's expenses on modification of the connection point. Also, methods of calculating of electric networks in steady state are described in this paper, particularly, linear calculations, because these are needed for the calculations in E-vlivy program, in which the possible options of Drahany wind farm's connection into network 110 kV, in various places, were modeled. The description of the E-Vlivy program is also included in this paper. The E.ON company's materials form the basis for this Master's thesis, which will later serve as one of the documents needed for Drahany wind farm’s connection point evaluation into distribution network 110 kV.

Evaluation of nonstandard operation possibilities of power sources in MV network
Čáslava, Jiří ; Opat, Jaroslav (referee) ; Topolánek, David (advisor)
This Master's thesis deals with solution of nonstandard operation connection of E.ON's 22kV distribution network in given area, considering the possibilities of operating dispersed electric power sources currently available, as well as possible power sources connected to the distribution network in the future and its potential operation limitation. A part of this paper is a description of calculation methods used for network evaluation in steady state, with emphasis on linear calculations used by E-Vlivy program, in which the operational possibilities are simulated. Therefore, a description of this program is also included. Suggested operation possibilities correspond with E.ON's valid distribution network operation rules. The outcome of this paper will serve to E.ON's 22kV network's controllers as materials for network operating in nonstandard operation states.
