“…A restoration system for maximizing the restorable loads in a distribution network using three different restoration schemes, a network state knowledge base (NSK) and a restoration knowledge base (RKB) was described in Ref. 34. A special NSK and RKB record format was proposed for storing network information and restoration steps.…”

Harrell's c-index or concordance C has been widely used as a measure of separation of two survival distributions. In the absence of censored data, the c-index estimates the Mann-Whitney parameter Pr(X>Y), which has been repeatedly utilized in various statistical contexts. In the presence of randomly censored data, the c-index no longer estimates Pr(X>Y); rather, a parameter that involves the underlying censoring distributions. This is in contrast to Efron's maximum likelihood estimator of the Mann-Whitney parameter, which is recommended in the setting of random censorship.

SUMMARYWith the fast-paced changing technologies in the power industry, new power references addressing new technologies are coming to the market. So there is an urgent need to keep track of international experiences and activities taking place in the field of modern power system restoration problem. This paper gives a bibliographic survey, mathematical formulations, and general background of research and developments in the field of restoration problem for past 35 years, based on more than 150 published articles. The collected literature has been divided into many sections, so that new researchers do not face any difficulty in carrying out research in the area of next-generation restoration problem under any environment.

“…Among these important publications are metaheuristics that use the multi-agent approach presented in [9], genetic algorithm, evolutionary approach and fuzzy sets, and the fuzzy non-dominated sorting evolution strategy presented in [10]- [12], heuristic optimization techniques presented in [13] and [14], a heuristic strategy based on a theoretical analysis of a search detailed in [15], a heuristic strategy that uses rules based on an operator's experience presented in [16], a heuristic strategy for the load transfer and specialized implementation of four steps in [17] and [18]. Furthermore, several methods were proposed to solve the restoration problem such as the application of expert system techniques analyzing group restoration, zone restoration and load transfer presented in [19], the heuristic generating the minimal paths to the boundary branches connecting the out-of-service area with the nearby area, presented in [20], service restoration using a fuzzy sets approach presented in [21], and the heuristic algorithm with an expert system that incorporates the network information and restoration strategies presented in [22].…”

This paper presents a comprehensive mathematical model to solve the restoration problem in balanced radial distribution systems. The restoration problem, originally modeled as mixed integer nonlinear programming, is transformed into a mixed integer second-order cone programming problem, which can be solved efficiently using several commercial solvers based on the efficient optimization technique family branch and bound. The proposed mathematical model considers several objectives in a single objective function, using parameters to preserve the hierarchy of the different objectives: 1) maximizing the satisfaction of the demand, 2) minimizing the number of switch operations, 3) prioritizing the automatic switch operation rather than a manual one, and 4) prioritizing especial loads. General and specialized tests were carried out on a 53-node test system, and the results were compared with other previously proposed algorithms. Results show that the mathematical model is robust, efficient, flexible, and presents excellent performance in finding optimal solutions.
