Description

  The present invention relates to an industrial energy management system, and more particularly to an energy management system in an industrial plant having a private power generation facility.

Industrial plants having private power generation facilities are roughly classified into two types: production facilities for producing products in each plant and private power generation facilities for supplying electricity and steam to the production facilities. The purpose of the production facility is to produce products, and the purpose of the private power generation facility is to supply necessary electricity and steam to the production facility.
The present invention relates to a system for planning an operation plan that satisfies the demands (electricity, steam) required by production facilities and that allows an in-house power generation facility to operate optimally from the viewpoints of fuel cost and energy amount control. .

  Conventional industrial energy management systems reduce the purchase energy cost as much as possible, reduce the amount of energy generation as much as possible, and create an operation plan that satisfies the demand demand (electricity, steam, etc.) with each single evaluation index. It was something to do. Moreover, the self-generated equipment characteristic which is the input value of the optimization calculation uses what is obtained from the equipment specification at the time of equipment design (for example, refer to Patent Document 1).
