Uma Rede Inteligente é uma rede elétrica que inclui uma variedade de medidas operacionais e de energia, incluindo medidores inteligentes, aparelhos inteligentes, fontes de energia renováveis e recursos de eficiência energética. O controle da produção e distribuição de eletricidade é um aspecto importante das redes inteligentes estudadas com o "AEL-BSGC", aplicativo de redes inteligentes de energia controlada por computador.
