Fundamentals of energy efficiency to management renewable energy sources in electrical grids Book in Scopus uri icon

abstract

  • This chapter shows a general overview of energy consumption classified by different industrial sectors. A comprehensive overview of electrical energy tariffs in the industrial sectors of Mexico and the United States is provided. By analyzing the charges of these tariffs in detail, it is aimed to identify potential areas for improving energy efficiency resulting in cost savings too. In a modern power system, energy waste is linked to active power losses, which can be minimized through different optimization approaches, for example, maximizing the use of renewable energy sources; on the other hand, the need to develop decarbonization programs in modern power systems entails expanding the energetic matrix, which is studied with JULIA-based power flows and carbon dioxide (CO2) emissions depending on the power demand. We developed algorithms in JULIA for calculating active and reactive power flows, carbon dioxide emissions depending on the technology of each generator, and CO2 emissions by transmission. Similarly, the optimization of distribution grids is analyzed to reduce the active power losses by identifying the optimal placement of a photovoltaic system focused on minimizing the active power losses and voltage drops. This chapter also includes a study case for understanding the fundamentals of demand-side management using a battery energy storage system of an interconnected microgrid. © 2024 Elsevier Inc.
