Optimal use of electrical energy and efficiency of the consumption are the two most important questions in today's industrial energy management. Suppliers buy energy from power plants and transmit it to the customers. Power consumed is the input for the end users, thus the supplier has no real impact on it. The supplier is subject to the stochastic changes in energy utilization and has limited possibilities to control power consumption; nevertheless, the supplier has an interest in keeping this power level as smooth as possible. One of the suppliers' compensation tools is the integration of remote-controlled heating equipment, such as electrical boilers and heaters that can be switched on by the supplier in low tariff periods. The aim of this project was to develop reliable methods for more efficient utilization of a centralized ripple control system (CRCS), through controlled storage and water heaters. This paper summarizes the results of the research on optimization of power consumption by CRCS. (C) 2013 Elsevier Ltd. All rights reserved.
