The world is changing, and so are the damages and loss of life and property from more frequent extreme weather events. Climate change is causing a steady increase in the intensity and frequency of severe storms, wildfires, and other natural disasters. Recent studies have shown an increase in electrical outage events correlated to extreme weather events from 50 per year on average in the early 2000s to over 100 annually on average during the past five years.1 These events cause substantial economic losses through infrastructure damage, manufacturing and labor disruptions, and property value losses.

“…In contrast, this paper focuses on the use of networked microgrids to manage the risks of igniting wildfires with a focus on equitable distribution of required power shutoffs. Furthermore, while [47] considers the use of microgrids to mitigate wildfire risk, it uses a much simpler formulation and does not model various microgrid capabilities or socioeconomic factors, as in this paper.…”

“…As the weather prediction methods have been illustrated above, in this subsection, we conducted an analysis of the correlated characteristics between weather patterns and outage distributions to characterize both rainfall and bushfire events. A novel method is introduced to establish a correlation between the severe weather risk index and the power network model, incorporating geographical information about the transmission lines [78]. However, it's worth noting that a long transmission line may traverse multiple weather regions, potentially encountering different weather conditions in each region.…”

A comprehensive review of uncertainties in power systems, covering modeling, impact, and mitigation, is essential to understand and manage the challenges faced by the electric grid. Uncertainties in power systems can arise from various sources and can have significant implications for grid reliability, stability, and economic efficiency. Australia, susceptible to extreme weather such as wildfires and heavy rainfall, faces vulnerabilities in its power network assets. The decentralized distribution of population centers poses economic challenges in supplying power to remote areas, a crucial consideration for emerging technologies emphasized in this paper. In addition, the evolution of modern power grids, facilitated by deploying the advanced metering infrastructure (AMI), has also brought new challenges to the system due to the risk of cyber-attacks via communication link. However, the existing literature lacks a comprehensive review and analysis of uncertainties in modern power systems, encompassing uncertainties related to weather events, cyberattacks, and asset management, as well as the advantages and limitations of various mitigation approaches. To fill this void, this review covers a broad spectrum of uncertainties considering their impacts on the power system and explores conventional robust control, and modern probabilistic and data-driven approaches for modelling and correlating the uncertainty events to the state of the grid for optimal decision making. This article also investigates the development of robust and scenario-based operations, control technologies for microgrids (MGs) and energy storage systems (ESSs), and demand-side frequency control ancillary service (D-FCAS) and reserve provision for frequency regulation to ensure a design of uncertainty-tolerance power system. This review delves into the trade-offs linked with the implementation of mitigation strategies, such as reliability, computational speed, and economic efficiency. It also explores how these strategies may influence the planning and operation of future power grids.
