Abstract
The current electrical system is transitioning towards a new technological model called the smart grid. The transition duration between the traditional Electric Power System (EPS) and the full smart grid depends on well-designed strategic plans, implementing transition models that are as close to smart grids as possible, based on the processes and technological resources available at the time, but always considering their economic feasibility, without which no solution thrives. In this article, we present a method for convergence of the traditional power distribution grid to the smart grid paradigm by retrofitting the legacy circuits that compose this grid. Our results indicate that the application of such a method, through a distributed system platform with integrated technological resources added to the legacy infrastructure, converts these passive grids into intelligent circuits capable of supporting the implementation of a smart grid with a broad scope of functionalities. Based on a novel retrofitting strategy, the solution is free from the cost of replacing or significantly modifying the legacy infrastructure, as verified in deploying other currently available solutions.
Highlights
The Electric Power System (EPS) is the largest globally implanted industrial complex ever recorded in human history
The results indicate a complete adaptation of the SmartLVGrid platform to the execution of this type of functionality, with the advantage of the Coordinator acts as a gateway that provides the interface among the Operators and the Supervision and Control Center (SCC), requiring only a Metropolitan Area Network (MAN) link for this
It is necessary to deepen the research, through the experimental analysis based on the implementation of physical prototypes, whether for laboratory or field tests, from the results obtained in this work, we can conclude that SmartLVGrid is a platform potentially:
Summary
The Electric Power System (EPS) is the largest globally implanted industrial complex ever recorded in human history. The study and definition of solutions applicable to the technological transition from traditional EPS (Legacy) to the smart grid paradigm, through strategies, methods, and systems (or models) that minimize impacts and optimize costs can contribute decisively to accelerate this process (called here of SG convergence). This work describes the SmartLVGrid platform and its strategy (method) applied to the convergence of low-voltage (LV) distribution grids toward smart grids paradigm, through retrofitting of the legacy circuits that compose them It presents the preliminary validation process, given from results of the experimental analysis made using the functional assay in a simulated and reduced model of the solution, using the SIMULINK program. Through experimental assays, using simulation resources (virtual environment), we establish an empirical basis which will serve as support for later and more advanced validation steps
