Optimal Location of Transformers in Electrical Distribution Networks Using Geographic Information Systems

Abstract

<jats:p>This research shows a heuristic model for the design of scalable and reliable electrical distribution networks. The algorithms presented allow to optimize the location of transformation centers using on their database geographic information systems from which it is possible to define user locations, candidate sites, possible routes for the deployment of the electricity grid and, in general, data for the reconstruction of the scenario. The model employs clustering and triangulation methods, as well as algorithms for creating a minimally expanding tree and the consequent site assignment for transformer placement. After setting the optimal locations for the transformer site, the algorithms compute voltage drops in secondary circuits, required transformation capability, execution times, and coverage achieved. The results obtained are adjusted to the requirements of an actual distribution power grid and show a good performance on the proposed scenario.</jats:p>

Geographical information system based optimal path routing of distribution networks

“…Technical requirements, for example, are far more essential than environmental factors. As a result, its corresponding value is 5, and the amount of its corresponding element in reversed row and column is 1/5 [ 17 , 19 ]. The fundamental scale parameters and their importance levels are presented in Table 1 , while Table 2 presents the important criteria coefficients.…”

Application of the Hurricane Optimization Algorithm to Estimate Parameters in Single-Phase Transformers Considering Voltage and Current Measures

“…One of the most important devices in this process chain, and more general in the electrical sector, are the transformers. These devices are responsible to interconnect the generation points with the transmission networks, at the same time are in charge to interconnect the transmission and subtransmission networks with the end users, which can be residential, industrial or commercial type [4]. This can be reached by raising the voltage level (high, medium and low voltage) at each stage [5].…”

Black-Hole Optimization Applied to the Parametric Estimation in Distribution Transformers Considering Voltage and Current Measures

“…Electrical transformers are essential devices in the whole electric sector since these devices help with interconnected generation and demand points through transmission lines by increasing the voltage levels from medium-to-high voltage levels [1]. When the transmission lines arrive at the subtramission and distribution substations, the voltage magnitude is again reduced to medium voltage levels to guarantee a secure electricity distribution service [2]; finally, at the load connection points, the voltage is reduced from medium-to-low voltage magnitudes in the final distribution stage [3]. Since the electrical transformers in the transmission and distribution sectors of the electricity service are vitally important, these devices play an important role in the dynamic and static behavior of the whole power system.…”

“…Since the electrical transformers in the transmission and distribution sectors of the electricity service are vitally important, these devices play an important role in the dynamic and static behavior of the whole power system. In the case of static behavior of the grid, one of the main aspects that must be studied corresponds to the number of power losses of the distribution system, since these are an indicator of the grid efficiency, especially in the distribution sector where power losses can vary from 6% to 18% [4], and the transformers can have more than 60% of the total power losses caused mainly by low loadability levels [2]. However, to know the percentage of power losses with a high level of precision, participation of the transformers in the distribution sector is required to reveal the electrical parameters of the transformers.…”
