Increase of paper mill energy efficiency by optimization energy supply system industry

Due to the high energy consumption in a paper mill, energy cost is an important part of the overall production cost of paper. Papermaking is a continuous process. Ensuring a continuous energy supply for this process would avoid production losses and supplementary energy consumption for restarting the installations. In this paper we develop an optimization model of the energy supply system from the perspectives of reliability and energy loss. Subsequently we use this model to analyze the energy supply system in order to find some solutions for increasing the energy efficiency and for reducing the cost of accidental outages.
