Managing the Enterprise Power Consumption Process

Abstract

Decisions made adopted in an enterprise power system in managing the electric energy consumption are analyzed. The urgency of the subject matter is stemming from the global-wide growth in the demand for electric energy and a systemic increase in the cost of energy resources. The study was carried out at an operating enterprise considered as an organizational and technical system. The subject area boundaries and the types of power engineering structures are determined at the enterprise. The system was decomposed into subsystems with identifying the applied organizational and technical managing/control actions. The power consumption management problem is formulated taking into account the minimization of financial costs, and its solution is found for one element. An algorithm for determining the optimal measure to be taken in the system is proposed, which offers a solution taking into account the specified criterion (financial expenditures for consumed electricity) and constraints (prototype functionality and energy payment budget). The algorithm checks the control actions in the course of system operation, which is the system lifecycle longest part. The structure of the decision making support system for managing the power consumption of an element is developed. The structure determines the sequence of measures to be taken in applying control actions with subsequently verifying the decisions made. Experimental studies were carried out on a system element, which that have demonstrated the practical applicability and financial savings, thereby testifying the possibility of further application of the study results in the power systems of enterprises belonging to all levels.
