“…Some work has hybridized both strategies by designing Expert Systems that solves a series of approximate problems optimally [14,9]. Interestingly, most of the work in planning PSR has focused on the details of scheduling power system restoration [2,3]. More specifically, what is the best order of restoration and how should system components be reconfigured during restoration?…”

This paper considers the power system restoration planning problem (PSRPP) for disaster recovery, a fundamental problem faced by all populated areas. PSRPPs are complex stochastic optimization problems that combine resource allocation, warehouse location, and vehicle routing considerations. Furthermore, electrical power systems are complex systems whose behavior can only be determined by physics simulations. Moreover, these problems must be solved under tight runtime constraints to be practical in real-world disaster situations. This work is threefold; It formalizes the specification of PSRPPs, introduces a simple optimization-simulation hybridization necessary for solving PSRPPs, and presents a complete restoration algorithm that utilizes the strengths of mixed integer programming, constraint programming, and large neighborhood search.

“…But the restoration procedure following a power system outage is commonly divided into three major steps [11], see Fig 1. These steps can further be divided into actions and iterations in the restoration process. The first step is to black start the first generators and add critical load or to add cranking power to the non black start generators.…”

Abstract-Since extended power outages causes severe stress on society and the restoration following a black out is a complex and time consuming task, efficient restoration strategies are needed. During the restoration, the power system undergoes continual changes and therefore it is subject to desired and undesired operations and failures which might be devastating. The main contribution of this paper is a new method to estimate the risk of an uncontrolled system separation in case of a loss of a transmission line or a transformer during a restoration process. The method in this paper assigns failure rates to the transformers and the transmission lines. Further, a graph theoretical method are used to find probability bounds for an uncontrolled system separation for a whole restoration sequence. In a numerical example are three restoration strategies applied to an IEEE 14 bus test system and evaluated. It is shown in the numerical example that the restoration strategy has an high impact on the probability for a system separation.

“…As the connecting stage of the restoration process, network reconfiguration is to restore the DGs' connection to the network and generate electricity again as fast as possible. It lays a foundation for the restoration of load by restoring important nodes and reconstructing the backbone network with key lines [6][7][8]. In conventional power systems, there are two types of black start strategies: the build-up strategy and build-down strategy.…”

A Parallel Restoration for Black Start of Microgrids Considering Characteristics of Distributed Generations

et al. 2017

Abstract:The black start capability is vital for microgrids, which can potentially improve the reliability of the power grid. This paper proposes a black start strategy for microgrids based on a parallel restoration strategy. Considering the characteristics of distributed generations (DGs), an evaluation model, which is used to assess the black start capability of DGs, is established by adopting the variation coefficient method. Thus, the DGs with good black start capability, which are selected by a diversity sequence method, are restored first in parallel under the constraints of DGs and network. During the selection process of recovery paths, line weight and node importance degree are proposed under the consideration of the node topological importance and the load importance as well as the backbone network restoration time. Therefore, the whole optimization of the reconstructed network is realized. Finally, the simulation results verify the feasibility and effectiveness of the strategy.
