In recent years, Utilities have been experiencing major changes in the use and implementation of technologies to enable better utilization and greater efficiency in their business processes. In this context the use of fixed capacitors, connected near the source of reagents, turns out to be a quick and inexpensive method for reactive power compensation and may play an important role in the distribution of electricity, contributing to improved quality and efficiency of service. The use of capacitors, if installed and properly located, are presented as an alternative to alleviate problems such as the unavailability of power transformers and electrical conductora, reducing losses in the system by Joule effect (heating) and improvement of voltage levels; hence reactive power planning is particularly important, applying techniques to optimize their implementation in low voltage networks. In this context, metaheuristic techniques are emerging as an alternative to solve the problem of optimal management of reactive power, defined as the number, location and optimal dimensioning of low voltage capacitors on the network. For this work has been selected genetic algorithms, which are noted for their calculation speed and simplicity. In this paper, an optimization model is developed using Genetic Algorithms. This algorithm obtains the number, location and capacity of each fixed network installed in a typical three phase capacitor radial secondary distribution. Possible locations of the capacitors in the network to be a quick and inexpensive solution to implement should be close to the three-phase power supplies with considerable sources of reactive power. For these variables, the optimization tool checks that the voltage drops in the distribution network are within the tolerances applicable standard and reactive supplied power by the proposed capacitor is less than the reactive power consumed by the substation the study period. To evaluate these restrictions has been taken into account measurement of peak demand in distribution transformers during a typical day of the month represented the highest energy demand in the last year and energy consumption of customers every month was Projected annual typical daily diagram considering the average increase in demand year. The goal of optimization is to determine the number, location and capacity of fixed-install phase capacitors, in ways that maximize the availability of power and saving energy loss, keeping stress levels in a tolerance range that meets the regulations (+/- 5% of nominal voltage according to the Technical Quality Standard Electric Service in force). The proposed optimization strategies allow optimally locating units reactive power compensation and manage reactive power to meet different load scenarios distribution transformers in a period of 24 hours. Finally, the benefíts associated with the optimum location of capacitors as to increase the availability of power in peak hours maintaining a voltage level within the range of tolerance according to current technical standards are checked. One of the main contributions of this work over previous work is the application of genetic algorithms to a real distribution network in Low Voltage modeled with the help of a Geographic lnformation System and a representative profile of demand in a period of annual operating.
