Projeto, instalação e testes experimentais preliminares de um sistema A-CAES (Adiabatic Compressor Air Energy Storage) em escala laboratorial

Abstract

In developed countries, per capita energy demand tends to be much higher than those with an inefficient economic model. Also, it is a fact that energy has been consumed in greater quantities over time. Fitting in the form of energy storage, the Adiabatic Compressor Air Energy Storage (A-CAES) can function as an intermittency stabilizer for electrical power systems generated by renewable or unstable systems, making this energy available at the appropriate place and time of its use, without having to send it to the distribution network that, at certain times, may be unavailable or unfit to receive it. The industrial plants use the concept of compression staged by large turbomachines and generation with the same equipment. The uses are a little different, but they aim to ensure the continuous and stable supply of energy. Aiming to contribute to the development of A-CAES systems, this research designs an A-CAES system on a laboratory scale and puts it to the test for a preliminary operational analysis. The system designed, built and analyzed has a storage capacity of 200L of compressed air at 12bar of pressure, with photovoltaic generation capacity of 5.9kW, electrical regeneration of 3.5kVA (two-phase alternator 220V), with an overall yield obtained experimentally of 18%.
