Formulation and Methodological Approaches to the Solution of the Multicriteria Problem of Selecting the Optimal Modes of Complex TPP Equipment

Abstract The article is devoted to the formulation of the problem of choosing the optimal operating modes for the equipment of cogeneration and condensing power plants with a complex composition of equipment on the basis of multicriteria optimization taking into account the factors of efficiency, reliability, and environmental friendliness. The general statement of the problem, the analysis of mathematical methods and methodological approaches to its solution, the choice of criteria for the indicated factors, and the design expressions for their determination are given. Taking into account the peculiarities of cogeneration condensing power plants, the statement of the problem is specified and an algorithm for its solution is proposed on the basis of an improved sequential step method. An assessment of the advantages and disadvantages of the proposed algorithm is given, and the ways of its improvement are indicated.
