“…This promotes the formation of mechanical sorption geochemical barriers with the formation of sedimentation zones. Technogenic flows continuously coming from NchGRES are superimposed on difficult natural conditions since the dominant components of emissions from the NchGRES are ash, sulfur dioxide, nitrogen oxides [8]. As a result, pollution centers with the domination of gley and hydrogen sulfide geochemical barriers have been formed in the bottom sediments of the Tuzlov and Kadamovka small rivers.…”

The work presents the results of studying the content of potentially toxic elements (Mn, Cu, Zn, Cr, Pb, Ni and Cd) in bottom sediments sampled at monitoring stations in the natural-anthropogenic systems of the Lower Don adjacent to the impact zone of the Novocherkassk Power Plant. The relationship between the content of metals in bottom sediments and their sorption properties is largely determined by the conditions of formation and the type of bottom sediments. Evaluation of the potentially toxic element content in sediments indicated that in particle size fractions (≤ 0.001 mm) could accumulate more than 15 times the levels of Cr and Zn and more than 6 times the levels of Cu, Cd and Ni in comparison to the particle size fractions that are 1.0 mm. Local zones of polyelemental pollution of bottom sediments with respect to Cu, Zn, Pb Cd and Cr were determined. These zones are confined to the geochemical sorption barriers of small watercourses of the power plant.

“…Watercourses are represented by small rivers Aksai and Tuzlov with tributaries Grushevka and Kadamovka, which are part of the Don River system. Since 1965, Novocherkassk Power Plant (NchGRES) is one of the largest thermal power plants in southern Russia, has been operating in this area [8]. NchGRES is surrounded by floodplain meadow landscapes.…”

“…It is believed that areas located at a distance of up to 4 km from power stations are subjected to the highest ecological disturbances (Minkina et al, 2013a). The power station, a year-round functioning, high electric and thermal output station mainly based on coal, is one of the largest producers of electricity in southern Russia and at the same time the major source of environment pollution (Linnik et al, 2019). Moreover, it is the sole hydroelectric station functioning on the local coal mining wastes and beneficiation products (anthracite fines).…”

This study is aimed at elucidating the fractionation of Cu and Zn in Haplic Chernozem and its alteration under the contamination to evaluate the extraction selectivity of different extractants and thus the efficiency of three sequential extraction schemes (Tessier and McLaren five-step and modified BCR three-step methods). General trends in the distribution of Cu and Zn speciations revealed with these three fractionation schemes suggest that they can be applied for the soils and the obtained results can be compared. Low mobility of potentially toxic metals (PTM) in the studied soil is suggested not only by their high content in residual fraction, but also by low contents of exchangeable and carbonate bound fractions (not more than 4-5 % Cu and 5-7 % Zn in the first two fractions). The highest contribution to the absorption and retention of Cu delivered from anthropogenic sources is made by organic matter and sesquioxides (up to 29 %); for Zn, by the nonsilicate Fe and Mn compounds (up to 25 %). However, the pattern of PTM extraction from soils varies during the application of different fractionation methods. The Tessier method is distinguished by a higher extractability relative to organic matter and sesquioxides. Therefore, this method is more informative for the contaminated soils. The McLaren method makes it possible to track the weakly bound species of compounds without the risk of involving other soil components. The BCR method is marked by simplicity of application and, therefore, recommended only for the noncalcic or low-calcic soils.

“…It is run by fossil fuel which pollutes the surrounding area and contaminates the soil with heavy metals which, in turn, is a threat to human life. [ 1 ] Moreover, the greenhouse gas emission from the conventional power plant increases the temperature of the environment. [ 2 ] The capability to sustain and fulfill the future power demand, the renewable energy sources (RESs) are becoming the most promising part in power generation industry to produce the green electricity.…”

In this paper, a student psychology-based optimization algorithm (SPBOA)-based proportional-integral-derivative (PID) controller is implemented for load frequency control (LFC) of an isolated hybrid power system (IHPS) and a grid-connected HPS (GHPS) models. In the designed models, a combined-cycle gas turbine, a diesel engine generator, a wind turbine generator and a solar photovoltaic generating unit are used as the main power generating units. A superconducting magnetic energy storage is used with IHPS model to improve the dynamic stability of the studied system. A single area power system is connected with IHPS model through a tie-line to form a GHPS. In the GHPS, a thyristor-controlled series controller and a unified power flow controller are associated with the tie-line power flow control. In this work, electric vehicle is also connected as a load to both the IHPS and GHPS models. The output profile of the proposed SPBOA-based PID controller of both models is compared with whale optimization algorithm (WOA) and quasi-oppositional-based WOA (QOWOA). The performance of IHPS and GHPS models are studied under the different load perturbations. The robustness analysis and frequency domain analysis in terms of Bode plot are also shown in favor of the SPBOA method.
