This research project deals with three interrelated problems associated with the optimization of the operation of active distribution networks for service restoration. The first problem that will be solved is related to the service restoration considering islanded operation, for which a new mathematical model will be proposed. The second method will be developed to evaluate the reliability of the network when several strategies are considered for service restoration and, therefore, the new model for restoration considering islanded operation will be considered in this topic. Finally, the third problem is related to the implementation of a meta-heuristic to allocate distributed generators in the network for improving its reliability indices, obtained using the method developed to solve the second problem. Several strategies for the network operation will be considered and evaluated for service restoration, including radial and connected operation, islanded operation, and meshed operation. The operation of devices such as distributed generators with and without black-start capability, capacitor banks, voltage regulators, and energy storage systems will also be modeled in the problem's formulation to improve the restoration process. Tests will be carried out using systems available in the literature, and it is expected that the new formulations and methods will improve the quality of the solutions obtained with existing approaches.
