Sistema de automação distribuído: uma abordagem baseada em multiagente aplicada a sistemas de distribuição de energia elétrica em média tensão

Abstract

The electric power distribution systems in medium voltage (SDMT) traditionally have radial topology with low reliability and low investment in technology, operation and automation, which restrict the evolution to smart grids (REI), in the short term, due to the high investment required. Within this context, this thesis aims to present a methodology for Agents-oriented Projects (POA) applied to the automation in medium-voltage distribution systems with different topological, automation, and operational features. The architectural design of Multi-agent System of distribution automation (SMAD) proposed comprises Multi-agent System of Fault Diagnosis (SMDF), Multi-agent System of Diagnosis, Localization, and Fault Isolation (SMDIF), Multi-agent System for Automatic Restoration (SMRA), Multi-agent System of Adaptive Protection (SMPA), Multi-agent System of Distributed Generation Management (SMGD), Multi-agent System of Microgrids Management (SMGM), Multi-agent System of Quality of Power Management (SMGQE), Multi-agent System for Energy Metering Management (SMGM), Multi-agent System for Voltage Control (SMCT), Multi-agent System for Equipment Monitoring (SMME) and Multi-agent System for Asset Management of power network (SMGA). The methodology proposed in the thesis uses a platform for development of agents in Python language (PADE) and a Configurator System and Network Simulator (SCSR) for building of metamodelos XML-CIM (Extensible Markup Language-Common Information Model) and XML-RNP (Node-Depth Representation) integrated to electrical calculation tools, both built in Smart Power Grid Group (GREI) to leverage the distributed systems applied to smart grids. The various systems communicate with each other using standard FIPA (Foundation for Intelligent Physical Agents), integrated into Intelligent Electronic Devices (IED) of protection, control and signaling existing in the SDMT, via standard communication protocol of the power sector. The stages of planning, analysis, design, implementation and testing of the methodology for development of the SMAD were tested and validated in the development of SMDF, SMDIF and SMRA subsystems. These subsystems have been developed in Python Agent Development Platform (PADE), FIPA standard, and deployed in a computer network integrated to IED of protection, via communication protocol MMS (Manufacturing Message Specification) of IEC 61850, and tested in the laboratory of Smart Power Grid Group of the Federal University of Ceará, presenting suitable results in location, insulation and re-composition of the SDMT so offline and automatically.
