TL;DR: In this paper, a comprehensive survey on network reconfiguration is presented to bring out a clear idea for future research, including manual or automatic switching operations, which can reduce power loss, increase system security and enhance power quality.
Abstract: Reconfiguration of radial distribution networks is becoming a viable solution for improving the performance of distribution networks. Configurations may be varied with manual or automatic switching operations so that all of the loads are supplied and reduce power loss, increase system security, and enhance power quality. Reconfiguration also relieves the overloading of the network components. The change in the network configuration is performed by opening sectionalizing (normally closed) and closing tie (normally open) switches of the network. These switchings are performed in such a way that the radiality of the network is maintained and all of the loads are energized. Several researchers have attempted to solve the power distribution network reconfiguration problem using various techniques. This paper presents a comprehensive survey on network reconfiguration to bring out a clear idea for future research.

TL;DR: A novel scheme of bus identification and multiphase data handling makes the implementation of the algorithm very simple and the performance of the proposed algorithm has been assessed by comparing it with several other established unbalanced distribution load flow methods.
Abstract: Many programs of real-time applications in the area of distribution automation, such as network optimization, Var planning, switching, state estimation, and so forth, require a robust and efficient load flow method for distribution systems. Such a load flow method must be able to model the special features of distribution systems in sufficient detail. Many approaches for unbalanced radial distribution system load-flow analyses have been developed. Among these approaches, the backward/forward sweep methods are commonly used due to their computational efficiencies and solution accuracies. This paper proposes a simple algorithm for unbalanced radial distribution system load flow analysis. The proposed algorithm is basically a forward/backward sweep method. A novel scheme of bus identification and multiphase data handling makes the implementation of the algorithm very simple. The proposed load flow algorithm has been implemented on three test distribution systems. The performance of the proposed algorithm has been assessed by comparing it with several other established unbalanced distribution load flow methods.

TL;DR: A simple algorithm for distribution system load flow with DG is proposed considering DGs as constant negative loads, and the results for three test distribution systems are presented.
Abstract: With increasing penetration of distributed generators (DG) in power distribution system, the distribution system load flow methods also need to be modified. Hence, the selection of suitable model of DG is important for the accurate load flow. In this paper, a simple algorithm for distribution system load flow with DG is proposed considering DGs as constant negative loads. The results for three test distribution systems are presented.

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.
Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

TL;DR: The Sine Cosine Algorithm (SCA) as mentioned in this paper is a population-based optimization algorithm introduced by Mirjalili in 2016, motivated by the trigonometric sine and cosine functions.
Abstract: The Sine Cosine Algorithm (SCA) is a population-based optimization algorithm introduced by Mirjalili in 2016, motivated by the trigonometric sine and cosine functions. After providing an overview of the SCA algorithm, we survey a number of SCA variants and applications that have appeared in the literature. We then present the results of a series of computational experiments to validate the performance of the SCA against similar algorithms.

TL;DR: In this article, the authors presented an original application of the Ant Colony Optimization concepts to the optimal reconfiguration of distribution systems, with the objective of minimizing the distribution system losses in the presence of a set of structural and operational constraints.
Abstract: This paper presents an original application of the Ant Colony Optimization concepts to the optimal reconfiguration of distribution systems, with the objective of minimizing the distribution system losses in the presence of a set of structural and operational constraints. The proposed algorithm starts from the current configuration of the system and proceeds by progressively introducing variations in the configuration according to local and global heuristic rules developed within the Hyper-Cube Ant Colony Optimization framework. Results of numerical tests carried out on a classical system and on a large real urban distribution system are presented to show the effectiveness of the proposed approach.
