Abstract

MÉTODO DE CÁLCULO IDEAL DA CONDIÇÃO DE OPERAÇÃO DE ENERGIA EM SIDERÚRGICA, DISPOSITIVO DE CÁLCULO IDEAL DE CONDIÇÃO DE OPERAÇÃO DE ENERGIA EM SIDERÚRGICA E MÉTODO DE FUNCIONAMENTO DE SIDERÚRGICA. Um método de cálculo ideal de uma condição de operação de energia em uma siderúrgica de acordo com a presente invenção calcula, usando um custo total de operação de energia da siderúrgica dentro de um período de tempo predeterminado a partir de um tempo atual como uma função de avaliação, uma condição de operação de uma instalação de energia na siderúrgica como uma variável de decisão, de modo que um valor da função de avaliação diminua, a cada tempo predeterminado dentro do período de tempo predeterminado, com base em valores reais e valores estimados de uma quantidade de geração e uma quantidade usada de serviço de energia para cada uma das fábricas compreendidas na siderúrgica. O método inclui uma etapa de cálculo da variável de decisão impondo uma restrição de igualdade para que a variável de decisão relacionada a uma instalação de geração de energia elétrica, incluída na instalação de energia, seja constante dentro de um tempo de agregação predeterminado.
