“…For electrical energy transmission systems, there are some reliability indicators that are defined and, for example in Poland, used basing on the regulation given by government authorities. For instance, these are [11,29] System Average Interruption Duration Index (SAIDI), System Average Interruption Frequency Index (SAIFI), and Momentary Average Interruption Frequency Index (MAIFI). SAIDI shows the average time of a long supply interruptions expressed in minutes per recipient.…”

“…It is very important not only to deliver power with the best possible quality parameters, such as fluctuations in RMS (root mean square) voltage value, high harmonic content, or frequency fluctuations [10], but also the continuity and reliability of supply is crucial. SAIDI (System Average Interruption Duration Index) and SAIFI (System Average Interruption Frequency Index) parameters [11] allow to easily measure the stability of the supplied energy, indicating the average time of interruptions in the network operation and the frequency of their occurrence, allowing to assess the quality of the topological structure of connections indirectly.…”

In this paper, a case study is conducted based on the real data obtained from the local Distribution System Operator (DSO) of electrical energy. The analyzed network represents connections and high-voltage switchgears of 110 kV. Selected graph parameters—vertex degree distribution, the average vertex degree, the graph density, network efficiency, the clustering coefficient, the average path length, and the graph diameter were examined, taking into account that in the analysis, some nodes were removed due to the different failures. For each failure, the possible effects on network parameters were tested. As a final result, it was shown that in the analyzed case, the removal of only five nodes could cause a significant (almost four times) fall of graph efficiency. In turn, this means that the whole analyzed network cannot be considered as a fault-tolerant.

“…Moreover, the supply reliability and continuity shown by SAIDI parameter (System Average Interruption Duration Index) or SAIFI (System Average Interruption Frequency Index) parameter are of great importance [8]. If the topology of power networks nodes connections is resistant to the net damages caused by different random events then the country economy is attractive for investors [9,10]. In Poland the PSE as the National System Operator, is responsible for the reliability of the highest voltages energy networks, while the local Distribution System Operators (DSO) are responsible for the remaining high-, medium-, and low-voltage lines.…”

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.
