Reconfiguration strategy for Fault Tolerance of power Distribution Systems using Petri net

This article presents a new heuristic strategy for the elaboration of a reconfiguration model for Distribution System Fault Tolerance (DSFT) using Petri nets (PN). Its intent is to model, analyze and optimize the program for the management of Smart Reclosers and Sectionalizers in a Smart Grid Distribution System, which together with the detection of faults, manage its isolation and the reconnection of a new system that maintains working capacity. In addition, according to the condition of protective equipment, thereby guarantees the supply continuity. The restoration of the distribution system with the support of the block diagram of the Study Guide Modes Start and Stop (GEMMA) arises. The objective is to design with PN a decision sequence for the programming design of intelligent electronic devices (RTU-IED-PLC) that allows the operation of the distribution network in fault status in branch form or in combination. This keeps quality levels of energy delivery to a vast majority of users, and is able to perform autonomously with the rapid restoration of customers for a Smart Distribution System. It also provides greater flexibility for the following: Control design for validation states (State feedback control), the Event Feedback control, and simplification and plans for the restoration of the smart restoration plans system intelligent distribution.
