OPTIMIZATION OF HPP OPERATION MODES BASED ON THE THEORY OF MARGINAL UTILITY AND HYDRO RESOURCE COST ESTIMATION

Abstract

The purpose of this article is to solve the problem of optimizing the operation of a hydroelectric power station based on the theory of marginal utility and assessing the cost of a hydro resource, taking into account the characteristic modes of operation of a hydroelectric power station. In this work, a universal method, which combines an optimization method and a method for assessing marginal utility. The method developed by the authors involves use the adequate representation of the incremental rate characteristic and the determination of the cost of the hydro resource for the control of the operating modes of the HPP. Using the example of the Novosibirsk HPPs and TPPs, an assessment of the energy efficiency, proposing the concept of a developed methodology for determining the price of water for HPPs, will be obtained. Based on the results of the implementation of the developed approach at Novosibirsk HPPs, the electricity sales price competitive electricity market can be matched with the electricity sales price generated at TPP, which will be approximately 370 ¢/kWh
