Powstańców Warszawy 12, 35-959 Rzeszów, Poland Abstract. A case study based on the real data obtained from the Polish PSE System Operator of the highest voltages electrical energy network is shown. The data about the interconnection exchange and some complex networks (graphs) parameters were examined, after the removal of selected nodes. This allowed to test selected network parameters and to show that the breakdown of only three nodes in this network can cause significant drop of its average efficiency. 1 Introduction The concept of complex systems and related theory give many interesting applications in modelling different real systems [1]. One of examples are power systems which can be exposed on different threats even leading to the risk of potential blackouts [2]. In this short paper, the real electrical network as a graph of nodes and edges is shown. Some of this network topological parameters are given and the interconnection exchange as an example of the power system security is shown. Selected parameters of complex networks are calculated and the removal of some network nodes caused by failure was done. This leads to the changes in the whole network topology shown in tables. The most important is the drop of network efficiency and in turn, the increase of transmission costs. The paper is organized as follows: after the short Introduction in Section 2 we show the complex systems and networks theory.

  • Part 3 Energy Policy: the Achilles Heel of the Baltic States
    THE BALTIC STATES IN THE EU: YEstERDAY, TODAY AND TOMORROW Extract from: A. Grigas, A. Kasekamp, K. Maslauskaite, L.Zorgenfreija, “The Baltic states in the EU: yesterday, today and tomorrow”, Studies & Reports No 98, Notre Europe – Jacques Delors Institute, July 2013. PART 3 ENERGY POLICY: THE ACHILLES HEEL OF THE BALTIC STATES by Dr. Agnia Grigas INTRODUCTION Nearly a decade following EU accession, the energy sector remains the most vulnerable national arena for Estonia, Latvia and Lithuania – an “Achilles heel” of the three Baltic states. The vulnerability stems from the fact that the energy sectors of the three states remain inextricably linked to and fully depended on Russia while they are virtually isolated from the rest of the EU, making them “energy islands”. This predicament is not only of concern to statesmen and strategists as energy effects almost every aspect of the Baltic states – the economy, industry and the wellbeing of citizens. The rapid inflation of the mid 2000s leading to the economic overheating and eventual economic crisis in 2008 was in part due to the rapidly accelerating costs of Russian gas and oil. Industry which accounts for a significant portion of total gas consumed (50%1 of total gas consumed in Lithuania, 21%2 in Estonia, 14%3 in Latvia) was also hard-hit. Gas prices are particularly sensitive for households who depend on gas for heating in the winter months, making up 10%4 of total gas used in Estonia in 2011, 9%5 in Latvia, and 5%6 in Lithuania, which represents 10 to 15% of their post-tax income7.

    Connecting Europe Facility - ENERGY LitPol Link Construction 4.5.1-0005-LT-W-M-15 Part of Project of Common Interest no 4.5.1 EXECUTIVE SUMMARY The Action "LltPol Link Construction" Is the main part of project of common Interest "LT part of Interconnection between Alytus (LT) and LT/PL border". Baltic States remain synchronously interconnected to IPS/UPS system, however before the Action implementation three Baltic countries were not properly integrated Into the wider energy networks of the rest of the European Union (the only power connection was the Estlink between Estonia and Finland) and were hence practically Isolated in the field of energy. The main objective and scope of the Action was to build Interconnection which will connect Lithuanian electricity system from Alytus substation 400 kV switchyard with Polish electricity system at Lithuania/Poland border. The Action consisted of two activities - construction of the high-voltage double-circuit power transmission line from Alytus to Llthuanla/Poland border and construction of 500 MW HVDC back-to-back converter station with 400 kV AC switchyard. The duration of the Action was ten months - from 28th April 2015 to 29th February 2016. As a result the link of 500 MW capacity connects Lithuanian and Polish power infrastructures for the first time. Completed Action allows further development of Interconnection between Lithuania and Poland - Implementation of 2nd phase of LltPo Link, comprising of construction of 2nd HVDC back-to-back converter station; that would enable Increase of capacity of Interconnection by another 500 MW to 1000 MW In total. Moreover, LitPol Link connected the grids of Baltic countries to those of Western Europe for the first time, thus ending the energy Isolation of Lithuania, Latvia and Estonia.

  • Change of Cross-Zonal Capacity Allocation Mechanism on Litpol and Swepol
    Change of cross-zonal capacity allocation mechanism on LitPol and SwePol Conditions for cross-zonal capacity calculation and allocation on LitPol and SwePol interconnectors In order to meet all security requirements of Polish power system (KSE) operation, PSE reflects the requirements regarding generation conditions in Poland in offered cross-zonal capacities. This refers to both the electricity export from Poland and import to Poland. Regarding the export, this is the case when available generation capacities are insufficient to meet power reserve requirements in the form of generation increase (upward reserve) and maximum possible cross-border exchange due to the capacity of interconnectors. In such situation, the priority is providing required power reserve level, as a precondition of security of electricity supply. It should be pointed out that this solution supports procurement of power reserve shortly before the electricity supply1, which in turn allows for not limiting generation capacities available on market due to earlier purchase of power reserves. In this way, electricity consumers have access to wider range of generation capacities within market processes in long-term, yearly, monthly and daily time horizons. Earlier procurement of power reserves would limit this scope, thereby worsening the effectiveness of commercial transactions. Also in case of the electricity import to Poland, the factors affecting its permissible values are the security conditions of the Polish power system. However, in this case is about not exceeding the minimum levels of electricity generation in given locations of the KSE in order to guarantee appropriate power reserve level in the form of generation decrease (downward reserve) and keeping quality parameters of energy supply such as voltage stability, short-circuit power, etc.
