The Crimean Peninsula

The Crimean Peninsula is the flagship of the development of renewable energy, as it is not only an actively developing region, but also a resort center. The energy complex of the Crimean Peninsula in recent years has increased due to the construction of new power plants (Balaklava TPP and Tavricheskaya TPP) with a total capacity of 940 MW, as well as the construction of new 220 and 330 kV transmission lines, which ensured that the peninsula’s power supply deficit was covered. A review of the regional development and use of renewable energy sources is carried out. Based on the data obtained, an analysis is made of the problems and prospects for the development of renewable energy in the region. The development of renewable energy for the Crimean Peninsula plays an important role in order to achieve environmental safety and develop the economic potential of the region. The paper substantiates the priority use of renewable energy in the region, as well as the solution of emerging problems with an increase in the share of renewable energy in the total generation. The appearance of excess electricity in the power system and the possibility of balancing the generated power of renewable energy and thermal power plants, while reducing the cost of electricity. Investment attractiveness and active population growth in the region leads to an increase in generating capacity and an increase in the maneuverability of the energy system with a significant impact of RES. The efficiency of renewable energy in the energy system, the world experience in managing renewable energy generation, the actual impact of renewable energy on the energy system in conditions of electricity shortage, and forecast work schedules of the SES wind farm provided by the electric power industry entities in the assigned way are taken into account when forming the dispatch schedule and are accepted at the request of the subject. The available experience of existing SES in the power system of the Republic of Crimea and the city of Sevastopol requires additional research, including through field testing of generating equipment. Further full-scale tests should be carried out under the conditions of a real electric power mode of the power system, which requires the introduction of modern information technologies that ensure the exchange of technological information and the implementation of appropriate control actions. The work is underway to create a regulatory framework for the control of renewable energy source operation.

The article presents the results of research on the development of the structure, methods and technologies for managing the Unified Energy System (UES) of Russia in the context of the digital transformation of the electric power industry. The analysis of the experience of managing complex socio-technological systems (STS) on the example of the UES of Russia and modern achievements in digital technologies resulted in defining the main directions of the formation of a network-centric approach to ensuring the reliability of energy supply to consumers and the country’s energy security in normal operating conditions and in emergency situations. A comparative analysis of the structures is carried out and examples of practically implemented fragments of the above systems are presented. The article also presents the stratification of control loops and the structure of ontological modeling for the functioning of the entire UES control system. It defines and mathematically substantiates the algorithms for forming decisions for the managing the power facilities in the level range from of the National Crisis Management Center to the operational personnel responsible for maintaining the mode of power systems and power facilities. The given examples of operating systems, SISFEC (state information system of the fuel and energy complex) and SRMS (stability reserve monitoring systems)actually confirm the correctness of the selected solutions of the network-centric approach to managing the UES of Russia. The provisions set out in the article determine the direction in developing the digital control systems for STS.

The article examines the consequences of the reform of the Russian electric power industry, which resulted in the formation and operation of: wholesale electricity markets in the European part of the country, including the Urals, and in Western Siberia; the system of state-owned companies transporting electricity; and the aggregate of market platforms for the retail electricity market. New phenomena are analyzed, in particular: the emergence of vertically integrated companies coordinating the production and combustion of fossil fuels in power plants; the emergence of competition in the heat market from the side of heat generating plants, which led to financial losses for the existing CHP plants that are part of heat generating companies - participants in the wholesale electricity market; the withdrawal of some heat consumers from the market and the construction of their own heat generating plants; failure to create a competitive retail electricity market. Measures are proposed to prevent the negative consequences of the detected phenomena.

Information about the problems arising from the uneven production and consumption of energy in power systems, including in the power system of the Republic of Uzbekistan, is given on the example of a daily electrical load schedule. It is noted that to successfully solve these problems, energy is accumulated in the hours of minimum consumption so that it can be used in peak hours with high consumption, and for this purpose, pumped storage power plants are used. A diagram of hydraulic energy storage is given at large pumping stations used to accumulate water in the upper reservoir in hours of minimum loads, and the accumulated volume of water is directed to generate energy, which can be used by pumping stations to supply additional water to its consumers, replenishing its losses in hours of hydraulic energy storage. The method of selection and optimization of the main parameters of this complex, based on minimizing fuel consumption in power plants while limiting the amount of accumulated energy based on the capabilities of water and energy resources of pumping stations, is presented. The calculations using the example of the Syrdarya thermal power plant show that with the integration of five nearby pumping stations into the process of energy storage and generation, significant cost savings are achieved, and the daily load schedule is significantly leveled.

Carbon Reduction

China’s electric power industry contributes a significant amount of carbon emissions as well as air pollutants such as SO2, NOx, and fine particles. In order to detect co-benefits of carbon reduction and air pollution control, this study analyzed the emission reduction, emission reduction factors, and synergistic effect factors of technical and structural emission reduction measures in the electric power industry in the Jiangsu, Zhejiang, and Yunnan provinces and Shanghai City. The main findings are: (1) the structural emission reduction measures in all four regions had positive co-control effects. Therefore, promoting renewables can achieve remarkable co-benefits; (2) the result demonstrated that the direct removal ability of pollutants by technical emission reduction measures was better than the structural emission reduction measures in all four case studies. However, there were no or few carbon reduction co-benefits associated with their utilization; (3) in all cases, CO2 had the highest emission factor value, which means that there is still room for synergistic carbon reduction; (4) air pollutants and CO2 emission intensity from the Yunnan power plants were much higher than that of the other three regions. In order to achieve the overall co-benefits, co-control measures should be promoted and strengthened in western areas such as Yunnan.
