Abstract
Fundamental and exploratory research in the field of energetics and rational nature management is currently focused on getting results in the field of the effective development and functioning of energy systems. Such systems are based on modern electrical equipment, including electrical machines and controlled power converters (active rectifiers and regenerative units (AC/DC), direct voltage converters (DC/DC), inverters (DC/AC)), conventional and non-traditional electric power based on renewable energy sources (RES).The Program of basic research in the Russian Federation on a long-term period (2021-2030 years) comprises the actual problems of development of energy supply, energy efficiency, renewable and alternative sources in industry and agriculture, including the issues of production technology, of conversion and storage of electric power.Electric power from the renewable energy sources requires its continuous correction, equalization and buffering i.e. a control system for the system operating modes.The paper presents a project of the power unit that provides both autonomous and traditional operation of a power plant having the possibility of recuperating electrical energy into the network. The structure and the composition of such a power unit is proposed, basic control strategies for an autonomous power generating plant having a capacity of up to 15 kW, operating from the variable low speed engine, also having the other sources of alternative energy with the possibility of power accumulation are considered.
Highlights
Federal Law of the Russian Federation of December 27, 2019 No 471 "On the amendments of the Federal Law "On Electric Power" in part of the microgeneration development" has defined the concept – "microgeneration facility"[1]
It is the facility for the production of electrical energy belonging on the right of ownership or on other legal grounds to a consumer of electrical energy, and its power receivers are technologically connected to power
The facility is used by the consumer for the production of electrical energy for both covering his own household or industrial needs and selling it in the manner prescribed by the main provisions of retail markets functioning if the amount of electric power produced by this facility does not exceed the maximum value of the connected power receivers of the consumer and is not more than 15 kW [1,2]
Summary
Federal Law of the Russian Federation of December 27, 2019 No 471 "On the amendments of the Federal Law "On Electric Power" in part of the microgeneration development" has defined the concept – "microgeneration facility"[1] It is the facility for the production of electrical energy belonging on the right of ownership or on other legal grounds to a consumer of electrical energy, and its power receivers are technologically connected to power. Alexander Khitrov, et al Power Unit for Power Supply of an Autonomous Facility Having Ability to Connect to General Industrial Power Supply in Recuperative Microgeneration Mode supply network facilities with a voltage level of up to 1000 V, as well operating on the basis of using renewable energy sources (including but not limited to). Local power systems specialist is engaged in development, implementation and maintenance of low power generation systems (wind, solar, bio, etc.) This type of competence can be used for the owners of country houses as well as in designing vertical farms. There has been a downward tendency of the cost of the permanent magnet synchronous motors (PMSM) that are increasingly used as starter-generators for autonomous-network electric power plants
