U organizaciji Odjela za obrazovanje i Odjela za elektroenergetiku Hrvatske Sekcije IEEE pro�li utorak odr�ano je predavanje pod naslovom:�"Transmission Expansion Planning of Systems with Increasing Wind Power Integration". Ili u prijevodu "Planiranje pro�irenja elektroenergetskog sustava sa pove?anim udjelom integracije vjetroelektrana".

Predava? je dr. Pavlos S. Georgilakis s National Technical University of Athens (NTUA) koji je u kratkotrajnom boravku na FER-u u okviru ACROSS projekta.

U predavanju se prezentira pristup planiranju razvoja prijenosne mre�e koji u obzir uzima intermitentnu proizvodnju elektri?ne energije iz vjetroelektrana. Razvijena metoda se mo�e koristiti za prou?avanje efekta pove?anog integriranja vjetroelektrana na planiranje razvoja elektroenergetske mre�e u sustavima koji zbog velike koncentracije vjetroelektrana u jednoj regiji imaju pove?anu nesigurnost proizvodnje iz istih.

Sa�etak predavanja na engleskom:

Wind power is going through a very rapid development. It is the fastest growing power source in the world, the technology is being developed rapidly and wind power is supplying significant shares of the energy in large regions. The integration of wind power in the power system is now an issue in order to optimize the utilization of the resource and to continue the high rate of installation of wind generating capacity, which is necessary so as to achieve the goals of sustainability and security of supply.

Wind turbines are of course mainly installed in places with good wind resources. This can lead to high concentrations of wind power in some regions. This means that large amounts of wind power will be generated in regions where the local consumption is low and the excess has to be exported. In order to do that it is necessary to have a strong transmission grid designed for the transmission of wind power. This basically means that it has the right capacity of power transport from the windy regions to the load centres. The main challenge is the rapid implementation of wind power, which means that the reinforcement of the grid has not been planned and that the procedure for determination of the transmission capacity is different due to the stochastic nature of wind energy.

An efficient approach for probabilistic transmission expansion planning (TEP) is presented that considers load and wind power generation uncertainties. The Benders decomposition algorithm in conjunction with Monte Carlo simulation is used to tackle the probabilistic TEP. An upper bound on total load shedding is used in order to obtain network solutions that have an acceptable probability of load curtailment. The method is applied on power system test cases and the effect of contingency analysis, load and mainly wind production uncertainties on network expansion configurations and costs is investigated. It is shown that the method presented can be used effectively to study the effect of increasing wind power integration on TEP of systems with high wind generation uncertainties.
