Development of a Synergetic Model of Water Management System Regimes Determining the Optimal Capacity of a Hydroelectric Power Plant Reservoir

The need for rapid development of the economic potential of our country requires increased productivity from all the sectors of the national economy that are direct participants in the water management system. Since the energy efficiency of all the components of the water management system is based on the energy industry, and modern requirements require the inplementation of green technologies, it becomes especially relevant to consider the key role of hydroelectric power plants in optimizing the operating modes of the water management system. At the same time, it is necessary to take into account the conflicting requirements of the participants of the water management system by drawing up a matrix of contradictions based on the analysis of water consumption regimes and the characteristics of the operating modes of each of the components of the water management system. Since this problem is multi-criteria, the work uses the Pareto-optimal set to find a compromise solution to determine the capacity of the reservoir, which would ensure not only the delivery of guaranteed hydroelectric power capacity, but also satisfy all participants in the water management complex. In this case, the minimum deviation of the actual water use by all participants of the water management system from its optimal value is used as a criterion. To obtain an optimal solution for maintaining the operating modes of the entire water management system, a synthesis of the theory of marginal utility and the construction of optimization models is used. The authors have compiled a synergetic optimization model that allows reflecting economic, reliability and environmental criteria. Using the example of the Novosibirsk hydroelectric power station and water management complex, it is expected to obtain an assessment of the economic effect from the implementation of the proposed criterion and the developed methodology for optimizing the water management complex. Based on the results of implementing the developed approach at the Novosibirsk HPP, it was possible to find the optimal regime for managing the capacity of the HPP reservoir and achieve an increase in the levels of the upper and lower pools, which most favorably affects the fishery regime and improves conditions for water transport.
