“…In fact, system operators have to deal with a large amount of data and alarms during electrical and weather emergencies. However, they have certain information processing bottlenecks [61][62][63], which may affect their capability to perceive and interpret the presented data in an effective and timely manner. This influences their reaction to electrical events, which is detrimental to the grid resilience.…”

a b s t r a c tA key driver for developing more sustainable energy systems is to decrease the effects of climate change, which could include an increase in the frequency, intensity and duration of severe weather events. Amongst others, extreme weather has a significant impact on critical infrastructures, and is considered one of the main causes of wide-area electrical disturbances worldwide. In fact, weather-related power interruptions often tend to be of high impact and sustained duration, ranging from hours to days, because of the large damage on transmission and distribution facilities. Hence, enhancing the grid resilience to such events is becoming of increasing interest. In this outlook, this paper first discusses the influence of weather and climate change on the reliability and operation of power system components. Since modelling the impact of weather is a difficult task because of its stochastic and unpredicted nature, a review of existing methodologies is provided in order to get an understanding of the key modelling approaches, challenges and requirements for assessing the effect of extreme weather on the frequency and duration of power system blackouts. Then, the emerging concept of resilience is discussed in the context of power systems as critical infrastructure, including several defense plans for boosting the resilience of power systems to extreme weather events. A comprehensive modelling research framework is finally outlined, which can help understand and model the impact of extreme weather on power systems and how this can be prevented or mitigated in the future.

“…Situation awareness is a key aspect in maintaining power system security, because it enables anticipation of critical conditions and effectively set preventive actions to mitigate them [1,2]. Lack of situation awareness was several times identified as one 5 of the major causes for large power system blackouts [3,4]. Various problems with situation awareness are related to missing information, i.e.…”

“…Various problems with situation awareness are related to missing information, i.e. the control room operator is not provided with the needed information [5][6][7]. Therefore, appropriate monitoring, visualization and decision support tools have to be developed to support the decision making process and to prevent or properly respond to electrical incidents in order to maintain power system 10 stability [8,9].…”

The paper presents a decision support tool for transient stability preventive control contributing to increased situation awareness of control room operators by providing additional information about the state of the power system in terms of transient stability. A timedomain approach is used to assess the transient stability for potentially critical faults. Potential critical fault locations are identified by a critical bus screening through analysis of pre-disturbance steady-state conditions. The identified buses are subject to a fast critical contingency screening determining the actual critical contingencies/buses. These two screenings aim at reducing the computational burden of the assessment, since only contingencies considered as critical are taken into account. The critical clearing times for the critical contingencies are determined. A preventive re-dispatch of generators to ensure a predefined minimum critical clearing time for faults at all buses is proposed, while costs are minimized. The results of the assessment are presented to the control room operator, who decides to accept the suggested dispatch or to repeat the assessment considering additional user-specific constraints. The effectiveness of the proposed method is demonstrated on a standard nine-bus and the New England test system.
