RESUMO:

Harmonic currents originated by non-linear loads flow through the electrical distribution system, causing distortion of the bus voltages and excessive power losses in the system. One of the most conventional solutions to keep the electrical power quality indicators at acceptable levels, such as voltage amplitude and frequency, unbalanced voltage and harmonic distortion, is the installation of passive harmonic filters in distribution networks. However, the planning of multiple harmonic filters in distribution systems can be interpreted as a discrete and combinatorial nonlinear programming problem. The combinatorial explosion worsens when increases the number of busbars in the distribution system. Few optimization techniques have been used to solve this problem, but not all are attractive because they cause a lon g time in the computational processing of the algorithms. For this reason, optimization techniques based on heuristic and metaheuristic methods have been improved due to their appropriate structure to solve optimization problems efficiently and quickly. This work presents a methodology based on the Ant Colony Optimization (ACO) metaheuristic, which together with a harmonic power flow algorithm, determines the optimal allocation and sizing of passive harmonic filters in electrical radial distribution systems. The objective is to reduce the total annual cost of active power losses, the cost of passive filters installation and the total harmonic distortion (THD), considering the constraints of the bus voltages and THD. In order to evaluate the proposed methodology based on multilevel ACO (allocation and sizing of filters), it was compared with another technique found in the literature. Thus, tests were performed on theses radial distribution systems with 10, 11, 18 and 34-bus balanced, and 33-bus unbalanced, with linear and non-linear loads.
