“…There are numerous lessons to be learned from these communities. Such lessons include successful implementation of secondary load control for wind generation smoothing through electric boilers, which provides essential heating services in several Alaskan communities (e.g., Unalakleet and Kotzebue, operated by the Alaska Village Electric Co-op) [137,138]. The installment of renewable energy, such as solar and wind in the remote Alaskan microgrids and in the island microgrids of Greece, has been driven by high electricity costs due to high cost of fuel and transportation of that oil and diesel [139,140].…”

Fundamental shifts in the structure and generation profile of electrical grids are occurring amidst increased demand for resilience. These two simultaneous trends create the need for new planning and operational practices for modern grids that account for the compounding uncertainties inherent in both resilience assessment and increasing contribution of variable inverter-based renewable energy sources. This work reviews the research work addressing the changing generation profile, state-of-the-art practices to address resilience, and research works at the intersection of these two topics in regards to electrical grids. The contribution of this work is to highlight the ongoing research in power system resilience and integration of variable inverter-based renewable energy sources in electrical grids, and to identify areas of current and further study at this intersection. Areas of research identified at this intersection include cyber-physical analysis of solar, wind, and distributed energy resources, microgrids, network evolution and observability, substation automation and self-healing, and probabilistic planning and operation methods.

“…Although the model is simplified, it does represent and describe the key behaviours of a typical diesel generator fed isolated microgrid. Note that in industrial practices, diesel generators are the major sources to power isolated microgrids as shown in [23, 24 ]. The system considered here represents a distribution bus fed through a transmission system equivalent.…”

Power system operation will encounter numerous voltage variabilities as the proliferation of renewable energy continues. Real‐time monitoring and communication technologies can potentially improve voltage stability by enabling the rapid detection of voltage deviations and the implementation of corrective actions. These corrective actions will only be effective in restoring stability if they are chosen in a timely and scalable manner. This study considers the problem of power systems’ load voltage control in order to simultaneously address both magnitude and time voltage specifications. In order to comply with grid codes and avoid unnecessary relay protection actions, a model predictive control‐based control strategy employing temporal logic specifications (TLSs) is proposed. The TLSs strategy is introduced as a formalism to control the voltage variation at a critical load bus against operational bounds over time. The control objective is to schedule optimal control input signals from the available supportive energy storage systems, which provide reactive power injections, leading to satisfying the specified finite‐time restoration described by the TLSs with minimal control efforts. The simulation results display that the TLSs strategy for power systems’ voltage control synthesis is extremely significant.

“…The absence of electricity can cascade down to the fresh water supply and, if available, to the district heating system, as represented in Figure 2. The missing heating and electricity can have a negative impact on Fi gure 1 shows how an electricity breakdown leads to the VoLL under normal circumstances Figure 2 shows how an electricity breakdown leads to the VoLL during the winter-times people in the cold climate and may reduce the health safety (Allen et al 2016). Private and health care losses may lead to a social loss, the size of which is diffi cult to determine since it is partly on the economical side and social side and can be also infl uenced directly and indirectly by the interruption in electricity delivery (Bliem 2005;Schröder;Kuckshinrichs 2015).…”

“…Firstly, the strong need for electricity by Arctic communities is analyzed. In the Arctic, electricity is not just a matter of productivity and entertainment, it is also essential for health and security due to the region's remoteness and harsh environmental conditions (Allen et al 2016). Secondly, the cost burden of electricity is considered, as high electricity costs create a considerable challenge in areas with existing high unemployment and poverty (Coates, Poelzer 2014;Koivurova et al 2008).…”

This paper reviews the electricity dependence of inhabitants in the western Arctic and provides an overview of past developments of electricity supply and how the current relation between the inhabitants and electricity is structured. In the Arctic, electricity takes on a special role due to its importance for security in addition to a matter of entertainment and productivity as seen in more temperate areas (Allen et al. 2016). This paper discusses the importance of electricity in the North, including the questions of what would happen to Arctic communities in the absence of an electricity supply. A hypothetical case of a blackout is presented. Furthermore, the burden of high electricity costs in the Arctic is discussed. The results of this research may contribute new knowledge for further research on the potential energy transition in the Arctic. Furthermore, the results emphasize the importance of energy and its supply security in the Arctic, which provides support for a focal point on energy security for energy transition policies.
