## 1 Introduction  
The use of modern technologies to improve the efficiency of organizing the functioning of manufacturing and urban processes and the provision of innovative services forms the basis of smart sustainable city and society concept [1, 2, 3, 4, 5]. Emerging environmental problems and other risks associated with an increase in the proportion of the population living in cities [1, 2] can be solved using assessing models [4, 5]. Special attention should be paid to the set of strategies for the conceptual development of urban areas, which are called\"smart\" cities in the literature, proposed by many studies [6; 7; 8]. The concept of a \"smart\" city aims to find new ways to meet these challenges based on the integration of information and communication technologies, the introduction of modern advances in artificial intelligence, big data processing, decision support technologies, and IoT [7; 8; 9; 10; 11; 12; 13; 14; 15]. Thus, in practice, the implementation of smart sustainable city concept allows to meet the growing needs of the present and future generations while minimizing the negative impact of the implemented technical solutions on the economic, social, and environmental components of the city [6; 7; 8; 9; 10]. The technological base for ensuring sustainable development of smart sustainable city (SSC) cities is the so-called \"smart\" solutions in the field of digital transformation of urbanized territories [9; 10; 11; 12; 13; 14; 15; 16; 17]. Examples of such solutions are smart power grids [16; 17; 18; 19; 20; 21], effective video surveillance systems [22; 23; 24], intelligent traffic management [25; 26], and housing and communal services [27]. However, the difficulty of electricity providing using city power supply networks limits the widespread implementation of such solutions. This is due the need of significant financial costs and additional construction works in some cases many times higher than the cost of the installed equipment. In addition, meeting the increased energy needs only through the use of traditional types of energy will lead to a deterioration of the environmental situation.  
These problems can be solved by using power plants that implement the concept of small-scale distributed energy, with generating plants located in the immediate vicinity of electricity consumers. This concept fits well with the use of renewable energy sources (RES) and, in particular solar and wind power plants. In addition, the advantages of such installations are environmental friendliness, which allows them to be used on almost any scale without causing damage to the environment, as well as their availability in almost every point of our planet, differing in radiation density by no more than two times [28; 29], which is very important for the implementation of the concept of a smart urban environment. However, despite the stated advantages, the widespread use of PGR in Russia is constrained by a number of disadvantages. One of the main such disadvantages of most PGR-based power plants is the incsonancy of the output power [30]. This disadvantage can be leveled by using in one design several generating plants that convert different types of renewable energy sources and an energy storage system. This is because various types of renewable energy sources, as a rule, have a weak correlation, which makes it possible to significantly reduce their influence in combined wind-solar installations.  
The authors analyzed the existing technical solutions, the simultaneous use of photoelectric converters (PV) and a wind power plant (WPP) [31]. This analysis shows that the technical implementation of such a combination does not always bring a noticeable synergistic effect and may lead to a decrease in the energy efficiency of each of the converters. In this regard, when designing these installations, it is necessary initially to take into account the design features of PV and wind turbines, as well as the features of their work.
