SUMMARY:

In view of the changes in the composition of the energy matrix and the gradual increase in demand for electricity, studies of techniques to mitigate technical losses in power systems are encouraged. Thus, considering the cost-benefit of existing solutions in the market, it is observed the generation redispatch as a more widespread solution. However, the Corrective Switching technique stands out for providing cost reduction and a shorter execution time, when compared to generation redispatching. In this sense, this paper aims to establish a comparison between both techniques, presenting their pros and cons and validating the results obtained in two distinct electric grids. In a first step, the methodology developed for the Corrective Switching technique selects, by means of the Relief Function, the most promising variants in order to eliminate the overload in an overloaded branch, without causing overloads in other branches. From this selection and the execution of the load flow, the variants are ranked according to the total electric losses of the electrical network, choosing the most efficient variant. In a second step, for the generation redispatch methodology, a linearization of the electric losses minimization problem is proposed by means of the Lagrange method and the Gradient method. Therefore, using the simulation software Scilab, two routines will be developed - one for each technique - that will be executed for the chosen networks in order to validate the results.
