Increasing the energy efficiency of the generating company through the selection of optimal operating modes by the criterion of maximizing profit

Abstract

A software package has been developed for functional control of a generation company according to the principles of enhancing energy efficiency. The article deals with issues of optimum work load of a generation company in terms of electrical power. For that purpose, a methodology is proposed for assessment of optimum modes of power stations within such a company based on the principle of equality of maximum income and maximum expenses. The example of Novosibirsk CHPP is used to present the key factors that influence the optimum mode of operation of a power plant (composition of equipment in use, prime cost of generated electricity and heat as well as energy related parameters of the equipment. A methodology is developed for optimization of the CHPP in terms of electricity and heat, and a new approach is proposed for splitting fuel consumption between types of generated energy).
