SOUSA, Jeovane Vicente de. Cloud Computing in the Smart Grids context: An Application to Aid Fault Location in Distribution Systems. 183 p. Ph.D. Thesis -São Carlos School of Engineering, University of São Paulo, São Carlos, 2018. Cloud computing has been envisioned as the main technology capable to integrate and manage many systems on a Smart Grid. Thus, this research aims to develop a cloud computing infrastructure to store and manipulate smart distribution system data. By analyzing the infrastructure of the main applications using cloud computing for smart distribution systems, an extensible architecture with essential services was proposed to host smart distribution systems services and applications. Based on this proposition, a cloud computing platform was developed using open source tools. A new application to reduce multiple estimation for fault location in radial distribution systems using datamining techniques over smart meter data was implemented using this infrastructure. An optimized version of the datamining tool known as DAMICORE (Data Mining of Code Repositories) was implemented as an extension to the proposed architecture basic services. The new cloud application was tested using hundreds of fault simulations through a test feeder, being able to reduce the line extensions with multiple estimation by more than 80% in the simulated fault cases. The results show that the proposed cloud computing architecture and infrastructure enable new smart distribution systems applications, contributing to the development of smart grids and diffusion of cloud computing in this context. As an additional contribution, the cloud application developed will help to reduce the multiple estimation for fault locations in distribution systems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
