Metodologia para reposição de serviço e gestão de carga em microrredes inteligentes

Abstract

This work presents the development of a methodology to service replacement and management loads in islanded smart grid by load shedding, supported by Distributed Generation, to avoid or reduce violations of continuity indicators, subject to penalties for infringement, established in Module 8 of PRODIST, ANEEL (2015a). To adjust the power demanded by the load to the power generated during the islanding of microrrede specifies to the best loads to be rejected by Multicriteria Methodology Analytic Hierarchy Process - AHP. In applying of methodology it was considered as criteria the continuity indicators that generate compensation to consumers for violation, and also it was considered the priority of continuity of supply to loads. Thus, for the formation of the island, is obtained as a preliminary result, a classification of loads in order of need for service. The best loads classified will be reconnected to microrrede until that GD units do not support new loads or that they violate any of the restrictions, being the remaining loads rejected. In continuously, they was made a reassessment in every pre-set period of time in order to identify new possible loads shedding to be made. This revaluation occurs in two distinct scenarios, both for typical day as for critical day. Any Violations of system constraints are checked by software of load flow calculation. Thus, obtained as final result a whole of loads to be served during replacement or continuity of the service.
