Development of advanced network functions for future electric power distribution systems


The potential benefits of the modernization of electric power distribution systems will only be achieved through the development of methodologies that improve utility processes traditionally considered to be challenging and costly. Among them, there are those characterized by the improvement in the quality and reliability of the electricity supply and the decrease in operating costs, such as the voltage and reactive power control and the detection of anomalies. The voltage and reactive power control is one of the most challenging and costly processes to the utilities, whose difficulty is in part due to the technical impacts resulted from the high power injection of ultra-dispersed photovoltaic generators and the recharge of electric vehicles in periods of low or no generation from distributed generators. Regarding the detection of anomalies, they are characterized by the detection of any abnormal or irregular state of operation of the system, as observed in the occurrence of faults and thefts (non-technical losses). Such anomalous conditions directly impact the revenue of utilities, also burdening customers. In this context, this work aims to develop methodologies to improve the two highlighted processes, voltage and reactive power control and anomaly detection, exploring the scenario of modern distribution systems. Additionally, the objective is to make scientific advances (by publishing the work), technological advances (with the transfer of technology) and training qualified human resources for the development of the productive sector (via scientific initiation, master, doctorate, and post-doctoral supervision).
