This work proposes a methodology, based on the Scatter Search metaheuristic, to solve the problem of capacitor placement in radial distribution networks. New proposals were made to achieve a better convergence and computer performance of the method. The objec- tive function to be minimized incorporates the total value of investments (acquisition, installa- tion and maintenance of capacitor banks) and also operational costs. To obtain the operation state of the system, a specialized radial load flow algorithm is used. The method also consid- ers the installation of fixed and switched capacitor banks. The results show that loss reduction and voltage profile improvement can be achieved with the installation of capacitor banks in the network, they were compared with those obtained by two alternative methods for the same problem. The methodology was implemented in MATLAB and tested with four systems pre- sented in literature: the 34 bus, 136 bus, 202 bus and 400 bus systems. From the obtained re- sults it was verified that the methodology presented a good performance
