Método para obtenção de uma estimativa da seção em falta e análise da qualidade da energia elétrica através do uso de sistemas multiagentes

Abstract

Smart Grids (SG) enable better management, control and monitoring of the distribution and consumption of electricity. Under the scenario of an SG, with smart meters that allow the exchange of information in the network, the use of Multi-Agent Systems (MAS) becomes viable to assist the communication between existing equipment, interconnecting them, allowing to maintain the high performance indexes and power quality required by regulatory agencies. The use of MAS makes the network more autonomous and flexible, enabling restoration, analysis and quality management in the supply of electric energy and, fault section estimation. Therefore, the modeling and simulation of a generic distribution network. The test system was developed using the HYPERSIM software, by OPAL-RT Technologies. Subsequently, an MAS architecture was designed to implement in the electrical grid. For the creation and development of agents, the Java Agent Development framework (JADE) was used. The intention is to estimate with good precision the section that the fault occurred, allowing a greater speed in terms of restoration of the affected section and correction of the problem. Studies of possible fault scenarios were developed in the test system, among the cases analyzed, the following stand out: meter connection branch, low voltage side of the transformer and medium voltage network of the transformer. In addition, it also seeks to analyze the power quality supplied to residential consumers, respecting technical indicators. The results obtained for all the analyzed scenarios were satisfactory, the faults were correctly located, allowing the reestablishment of the energy.
