Automation of control of electric generators from renewable energy sources in hybrid power supply systems

Abstract

The article notes that due to the increasing number of electricity generating equipment based on renewable energy sources and consumers of electricity received from them, it becomes necessary to combine generating sources, consumers and control units into autonomous electric power systems. Due to the uneven generation and consumption of renewable energy sources under the influence of external conditions (wind, solar radiation, etc.), renewable energy sources should be reserved by means of traditional energy in the so-called hybrid mode, when traditional alternators must work together with renewable energy sources. In this case, the task of creating a tracking inverter that converts direct current (DC) to alternating current (AC) according to the characteristics of the AC generator arises. At Bauman Moscow State Technical University the experimental samples of a DC-to-AC inverter with its own logic and microcontroller have been developed and created. They control the conversion mode either by the signals of the reference AC network, or by the signal of the microcontroller. The proposed devices are designed to fully automate power generation processes and power consumption processes in hybrid power supply systems and are designed to manage input and output generating capacities and power consumers to ensure maximum efficiency of power generation from renewable energy sources.
