Analysis of the main approaches, methods of selection and justification of the parameters and modes of wind power plant for integration into the work of the electric power transmission

Abstract

One of the priority directions for the development of the electric power industry in Ukraine is the development and use of alternative and renewable energy sources, which leads to a reduction in dependence on the import of electricity. A large part of Ukraine's territory is characterized by favorable conditions for generating electricity using modern wind power plants.
 The article discusses the integration of wind power plants without considering other renewable energy sources. Compared to other sources of renewable energy, the operation of wind power plants has a random nature of electricity production, as the generated power can significantly vary during a day. This requires to take into account certain requirements for power systems during the integration and co-operation with wind power plants. Therefore, in the paper, wind power plants are considered separately from other sources of renewable energy, as they have their own peculiarities and can affect the operation of power systems.
 Integration of a significant amount of renewable energy sources, including wind power plants, into power systems requires solving various tasks related to the characteristics and functionality of such plants, as well as the structure of the generating sources of power systems. Among these tasks, it is necessary to ensure the necessary reserve capacity to timely compensate for changes during electricity generation, maintain the reliability of power system operation, and take measures to compensate for possible reduction in the quality of electrical energy. In fact, the processes of changing the power generated by wind power plants occur quite rapidly, especially in case of sudden deterioration of weather conditions, which is a fairly common phenomenon.
 The methods of selection and justification of parameters and operating modes of wind energy installations for integration into electric power systems have been analyzed. Various approaches to the selection of wind energy installations parameters and modes are described in the work, focusing on methods that ensure system reliability or adequacy of generation.
 Methods for selecting and justifying parameters and modes of wind power plants for integration into operation of power systems based on power and energy balance have been formulated. Key indicators that consider electricity demand conformity are defined in the work, along with approaches to balancing energy production and consumption.
 An evaluation of the effectiveness of wind power plants in different integration modes into power systems operation has been performed, taking into account economic aspects. The impact of different modes on the rational use of generated energy, particularly in cases of insufficient and excess generation, is examined, and economic indicators associated with these modes are considered.
 An analysis of the exact match mode (zero imbalance) of wind power plants in the context of integration into operation of PSs has been conducted. The utilization of storage and auxiliary maneuvering capacities' effects on the duration of the exact match mode and the level of zero imbalance are determined.
