Benefícios do armazenamento de energia em sistemas de transmissão: uma revisão e uma aplicação a um sistema de pequeno porte

Abstract

This study aims to demonstrate the benefits and the need for using energy storage systems in the operation of electrical power transmission systems, given the new characteristics imposed by the advancement of the energy transition, due to the increasing penetration of renewable energy sources with the intention of reducing the emission of greenhouse gases. Different energy storage technologies that can be used in electrical grids offering different supports are addressed. In addition to demonstrating the main services that an energy storage system with batteries can provide to the electrical power system. The proposed case studies, together with the analysis of the results of the simulations performed, demonstrate the benefits of using an energy storage system with batteries in the operation of an electrical system, with the presence of wind generation with its stochastic characteristics, reducing operating costs and managing power flows in the transmission lines.
