“…5. Hourly gas consumption and temperatures for two Wednesdays in the weeks CW3 and CW4 [4], [5] Experience in the operation of both power systems shows that power consumption in at its highest in the midweek. In the example of a short-term temperature drop on 24 January 2006, the highest power consumption was achieved in the middle of the fourth week, on Wednesday and Thursday.…”

“…It is noticeable that the increase in gas consumption during the fourth week amounted to ΔWg ~ 55.3 GWh, and the increase in electrical energy consumption to ΔWe ~ 5.5 GWh. and natural gas (GPZ) for wider area of Zagreb during the week (CW4) in January 2006 [4], [5], 12]- [14] In the past period, the Croatian gas and electric power systems were expanded and upgraded. Similar occurrences of a short-term temperature drop lead to mostly similar responses in the power systems, despite the fact that several new possibilities occurred for procurement of energy-generating products.…”

“…It was noticed that in this specific example of a temperature drop, none of the systems went through a significant disturbance which would have unforeseeable consequences, such as a partial or complete blackout, even with exceptionally high additional load and strained operation of the system. [5] The Croatian power and gas system are interconnected, complementary systems, and their mutual influence is especially conspicuous during a colder period of the year. This is the reason why a disturbance in one system is transferred to the other.…”

Electric and gas systems are two complementary, interconnected energy systems. Each of the systems has a different size and coverage. Their networks cover different areas, the structure of their customers varies across regions, and their presence varies in industry and households. The interrelatedness of these systems is both direct and indirect. The direct interrelatedness is visible in the tasks performed by the gas system in its function of a supplier for electricity production plants. Other than the mentioned direct connection, tasks performed by these two systems complement each other while supplying the consumers, for instance in tasks of heating, hot water preparation, and similar. However, there are also some specific features that create an impression that some systems' elements are separated. The indirect connection regards climate conditions. The aim of the paper is to analyse and present the impact which a temperature drop has on electric and gas system, as well as to analyse the interrelatedness of the two systems in extreme weather conditions taking Zagreb, Croatia as an example area. In winter the consumption of electrical energy and gas rises considerably. Any shortage leads to reactions. A threat to one system indirectly endangers the other. The paper tries to clearly present the systems' very important interrelatedness and interdependence in terms of higher demand for energygenerating products using the example of temperature drop. An immediate and considerable temperature drop provokes very similar responses from both systems. This phenomenon has not been recognized clearly enough by the professional community, and its consequences have not been fully considered.

“…Partial or complete blackouts can be caused by wide area disturbances such as angle instability, cascade tripping, etc. Experiences from the latest blackouts in the USA [1] and Europe [1][2][3][4] reveal the need for wide area information acquisition for better power system operation. Additional, energy markets within the power industry deregulation pushed operation of electric power systems towards the limits and increased the complexity of power system operation.…”

This paper presents functionality of developed wide area monitoring system (WAMS) and its implementation in Slovenian transmission system. The system enables real-time exchange of selected phasors between transmission system operators. Additionally, recordings captured on November 4 th 2006, when the UCTE interconnected grid split into three areas are presented and discussed. At the end some indications of possible future development of wide area protection and control system are given.
