Abstract

This dissertation aims to develop a methodology to provide adequate Energy Restoration Plans (ERPs) in contingency situations to large-scale distribution systems (with thousands of lines, load buses and sectionalizing switches), considering the existence of voltage regulators, capacitors banks and different types of sectionalizing switches. The proposed methodology considers the operational characteristics of different types of sectionalizing switches (existence of remote control, possibility of open-load and/or short-circuit, etc.) for the purpose of obtaining ERPs. Usually the developed methodologies consider only the existence of remotely controlled and manually controlled switches, excluding other operational characteristics of the sectionalizing switches. As the service restoration problem is combinatory with multiple objectives and constraints, the proposed methodology is based on Evolutionary Algorithms, multiobjective optimization techniques and on the data structure named Node-Depth Encoding. The Node-Depth Encoding is used to computationally represent, in an efficient way, the topology of the distribution systems. The proposed methodology is validated through computational simulations performed in real large-scale distribution systems. (AU)
