“…Pham et al [52] propose to use distributed generators to maximize the amount of load that can be restored after a blackout, sectionalizing the network to select which demand to serve and using the black-start capabilities available. Stefanov et al [53] propose a decision tool to position resources, including units with black-start capabilities and timelines, to bring the system back after a disturbance. These authors propose several models, including optimizing the utilization of the timelines available during the restoration process, considering the minimum amount of generation adjustments required and coordinating between adjacent systems to support restoration in neighboring areas.…”

The Effects of Infrastructure Service Disruptions and Socio-Economic Vulnerability on Hurricane Recovery

Hurricanes and extreme weather events can cause widespread damage and disruption to infrastructure services and consequently delay household and community recovery. A subset of data from a cross-sectional survey of 989 households in central and south Florida is used to examine the effects of Hurricane Irma on post-disaster recovery eight months after the landfall. Using logistic regression modeling, we find that physical damage to property, disruption of infrastructure services such as loss of electric power and cell phone/internet services and other factors (i.e., homeowner’s or renter’s insurance coverage, receiving disaster assistance and loss of income) are significant predictors of post-disaster recovery when controlling for age and race/ethnicity.

“…The sustained steady‐state overvoltage and transient overvoltage caused by energizing high and extra high voltage unloaded or lightly loaded transmission lines during restoration process is a critical issue, which have negative impact on restoration of the non–black‐start units. While energizing restoration path under no load condition, the massive reactive power generated by distributed capacitance of transmission lines can lead to sustained steady‐state overvoltage, and the large inrush current caused by switching transformer under no load condition may cause ferro‐resonance overvoltage and increase the likelihood of tripping of transmission lines.…”

Summary The extended black‐start strategy is new exploration for black‐start restoration of power systems, in which more than one non–black‐start unit can be restored simultaneously during the black‐start stage. This paper presents a multiobjective optimization method coordinating unit restarting with load restoration for extended black‐start decision making. The objective functions of the black‐start restoration optimization are defined as restoring non–black‐start units and unserved loads as much as possible under steady‐state and transient system operation constraints. A hybrid algorithm combining the lexicographic method with the improved bacterial foraging algorithm is used to solve the defined optimization model. The proposed method has been tested on the IEEE 118‐bus system and the southern Hebei power system of China, and the test results verify the effectiveness of the proposed decision‐making method.

“…However, in the stage of the start-up or under low-output conditions of generating units, critical loads should not be picked up to avoid a second failure. The dispatchable loads are non-critical and can be used to provide the required variable capacity to balance the output of restored generating units and improve the controllability of the system [30,34]. Therefore, sufficient dispatchable loads should be guaranteed in subsystem i, i.e.,…”

“…Since dispatchable loads can provide the variable power demand, they are widely used in power system operation, e.g., in demand side management [32,33]. For power system restoration, they can be restored flexibly to balance the output of generating units [30,34]. Especially, during the start-up process, a generator cannot be controlled effectively since its control system is designed for use between minimum and maximum load [12].…”

Parallel restoration is a way to accelerate the black-start procedure of power systems following a blackout. An efficient sectionalizing scheme can reduce the restoration time of a system, taking into account the black-start ability, generation-load balance of subsystems, restoration time of branches, start-up time of generating units, and effects of dispatchable loads and faulted devices. Solving the sectionalizing problem is challenging since it needs to handle a large number of Boolean variables corresponding to the branches and nonlinear constraints associated with system topology. This paper investigates power system sectionalizing problem for parallel restoration to minimize the system restoration time (SRT). A novel sectionalizing method considering the restoration of generating units and network branches is proposed. Firstly, the minimum spanning tree (MST) algorithm is used to determine the skeleton network of a power system. Secondly, the number of subsystems is determined according to the number of black-start units. Based on the skeleton network, candidate boundary lines among subsystems are identified. Then, constraints are evaluated to identify feasible sectionalizing schemes. Except commonly used constraints on power balancing and black-start units, this paper also considers using dispatchable loads to meet the minimum output requirements of generating units. Finally, the sectionalizing scheme with the minimum SRT is selected as the final solution. The effectiveness of the proposed method is validated by the IEEE 39-bus and 118-bus test systems. The simulation results indicate that the proposed method can balance the restoration time of subsystems and minimize the SRT.
