RESUMENEl problema del control de la demanda y el consumo de energía en empresas productivas y de servicios constituye una importante oportunidad para la reducción de los gastos asociados al uso de la energía eléctrica. En el presente trabajo se obtiene un modelo de compensación basado en la técnica de algoritmos genéticos que permite complementar el procedimiento manual de control de demanda, usualmente denominado acomodo de cargas, de forma tal que se obtenga mínimo consumo de energía en el horario pico, con mínima demanda máxima y mínima discontinuidad del gráfico de carga. El procedimiento resultante fue implementado utilizando las herramientas de programación del MATLAB versión 7.8 (R2010a) de la Global Optimization Toolbox. La efectividad del método se demuestra por medio de su aplicación a un caso de estudio real en el área de servicios a la producción de la Empresa Cervecería Tínima de Camagüey, Cuba.Palabras clave: Control de demanda, acomodo de cargas, algoritmos genéticos.

Abstract-This paper describes the application of the Opt-aiNet algorithm to the reconfiguration problem of distribution systems considering variable demand levels. The Opt-aiNet algorithm is an optimization technique inspired in the immunologic bio system and it aims at reproducing the main properties and functions of this system. The reconfiguration problem of distribution networks with variable demands is a complex problem that aims at identifying the most adequate radial topology of the network that complies with all technical constraints in every demand level while minimizing the cost of power losses along an extended operation period. This work includes results of the application of the Opt-aiNet algorithm to distribution systems with 33, 84, 136 and 417 buses. These results demonstrate the robustness and efficiency of the proposed approach.

“…Most authors have used different well known heuristics (branch exchange [2,3,21], branch and bound [1,4], simulated annealing [5]), other heuristic rules or meta-heuristics [7][8][9][11][12][13]15,17,22,23,25,27,28] or multi-agent technologies [20]. On the other hand, some authors have developed methods based on evolutionary computation techniques [6,14,16,18,19,24,26,29,30]. An important drawback of these methods is the fact that they solve the reconfiguration problems as single objective problems.…”

Pareto Optimal Reconfiguration of Power Distribution Systems Using a Genetic Algorithm Based on NSGA-II

Reconfiguration, by exchanging the functional links between the elements of the system, represents one of the most important measures which can improve the operational performance of a distribution system. The authors propose an original method, aiming at achieving such optimization through the reconfiguration of distribution systems taking into account various criteria in a flexible and robust approach. The novelty of the method consists in: the criteria for optimization are evaluated on active power distribution systems (containing distributed generators connected directly to the main distribution system and microgrids operated in grid-connected mode); the original formulation (Pareto optimality) of the optimization problem and an original genetic algorithm (based on NSGA-II) to solve the problem in a non-prohibitive execution time. The comparative tests performed on test systems have demonstrated the accuracy and promptness of the proposed algorithm.
