Load control implementation in the energy intensive industry

This paper presents the principal solution for a real time load control application in the industry under the conditions of open electricity market. The aim of the study is to create the basic concept of a PLC controlled load optimization system for the group of energy intensive machines. The optimized load curve calculations for the specific machine or for the aggregated group of machines in the industry production process have been proposed using the optimization algorithm. The paper covers the main aspects and assumptions used to assess the possible demand side management revenues for the industry. The application is used to optimize the industry production cycles operation according to the day-ahead spot market price information. The developed application and its results could be used by the industry to optimize the whole production line electricity cost.
