Market Relations

In modern conditions of market relations in the electric power industry, a mechanism is needed to regulate the purchase and sale of power, which should not lead to a deterioration in the EPS reliability. Competitive power take-off became the main component of this mechanism. Within its framework, nuclear power plants, hydroelectric power plants, new power units, as well as thermal power plants, which are necessary for heat supply to consumers, are mandatory selected. The article examines the process of price formation for capacity, its relationship with demand, shows the main features that affect its final indicators.

The article considers modern problems and problems that currently exist in hydraulic engineering and hydropower, problems of land and water resources. And also problems of training of experts. able to solve these problems Recently, the problems caused by existing large hydraulic structures are increasingly mentioned. The main problem is that the nodes of hydraulic structures often form artificial reservoirs of a large plane. It often happens that the depths of reservoirs are insignificant. This situation is very unsatisfactory because the land is used irrationally. which is a valuable resource and has a high cost and can be used effectively for agriculture. Creation of hydraulic structures, complexes of hydraulic structures significantly change the hydrological, biological. salt and thermal regimes of the river on which they are built, the regime of groundwater movement, cause climate change in the surrounding areas. Cascades of hydraulic structures have a special influence. As an example, we can cite the Dnieper cascade of hydroelectric power plants and compare the area of its reservoirs and the amount of electricity generated by its power plants with the world's largest hydroelectric power plants. In addition, shallow water bodies cause a significant deterioration in water quality. And since reservoirs are often a source of water supply for settlements and industrial enterprises, this situation is controversial. Intensive construction of hydraulic structures and their complexes took place during the twentieth century, many of them exhausted their resources and needed either reconstruction or decommissioning. The reasons for this state of affairs are the development of technology, the emergence and development of other alternative energy sources for thermal and nuclear power plants, other than hydraulic. Also, since the construction of many buildings, approaches to determining their profitability and efficiency have changed. Aspects of training specialists in hydraulic engineering and water engineering, able to solve these problems of the industry today, and those that will face them in the near future are considered. The ability of a competent professional to anticipate the consequences of any action must be an integral part of it. Attention is drawn to the need to apply conceptually new approaches to solving problems of construction of new hydraulic and hydropower facilities, operation and reconstruction of existing facilities.

The activity of any enterprise is always associated with risk. This is especially true of hydropower enterprises, since they work in the conditions of renewable energy sources, which are directly dependent on nature. This necessitates the introduction of the concept of risk management, which will take into account risk factors in the process of developing and approving management decisions.Hydroelectric power plants play an important role in ensuring the required quality of electrical supply, participating in regulating voltage and frequency, covering the uneven part of daily load schedules, guaranteeing measured operation modes of nuclear and thermal power plants, increasing the safety and economy of operation of the final cycles load, performing the function of a temporary emergency and operational power reserve.The purpose of this article is to analyze the characteristics of risk management in hydropower, as well as to justify the development and feasibility of introducing the concept of risk management in hydropower.

The determining value of the Kola NPP in the structure of the Kola electric power system is shown. The mutually complementary operation of the 1,760 MW KAES with seventeen hydroelectric power stations with a capacity of about 1,600 MW and two 240 MW thermal power plants makes the region's power supply system unique, producing the cheapest electricity in the North-West of Russia. The issues related to the further extension of the operating life of the existing nuclear power plant and the construction of theKola NPP-2 in the future are considered.

Abstract This work is devoted to the problem of utilization of waste heat from condensers of thermal power plants and nuclear power plants. The waste heat of the condensers of TPPs and NPPs, together with the circulating water, enters the environment, causing its thermal pollution. The use of this heat in an energy-biological complex, for example, in fisheries, increases their efficiency and solves an environmental problem. Compared to ordinary ponds, this energy complex has an almost year-round increase in biomass and accelerated maturation of producers. The article presents a developed methodology that makes it possible to assess the effectiveness of such a fishery. Calculations using this method were carried out for a fish farm raising sturgeons on the basis of the waste heat of a nuclear power plant with a VVER-1200 reactor and a K-1200-6.8/50 turbine

The results of the analysis of the problems associated with the development of the world solar energy are presented. It is noted that at the present stage of the electric power industry, the potential of renewable energy sources (RES) is still poorly realized. The specific issues of water-energy modes of operation of hydroelectric power plants (HPPs), operating in symbiosis with solar photovoltaic installations (SPEU) have been identified, the schedule of which should be the same. It is shown that the operation of hydroelectric power plants and SPEU in the joint electric load schedule makes it possible to obtain a constructive and economic effect due to the fuel saving of power plants of various types, including thermal ones. The maximum capacity of the HPP-SPEU power complex is optimized by the installed capacity of the HPP while observing the full duplication of the SPEU capacity by other power plants of the energy system. It is shown on the example of the Lagdo hydroelectric complex in the northern Cameroon that under the conditions of developing countries with a large solar and hydraulic potential (Cameroon, Zimbabwe, Uganda, etc.), as well as for the southern regions of Russia, SPEU can produce up to 75% of the annual electricity generation during the low-water period of the year at its joint work in the energy complex with the hydroelectric power plant. This makes it possible to facilitate the redistribution of the river fl ow during the entire low-water period without attracting additional useful storage capacity of the reservoir. The developed methodology for optimizing the water-energy regulation regime can also be applied during the operation of the HPP of the HPP-SPEU energy complex along the watercourse, i.e. with daily flow regulation.
