Abstract

Abstract. It is suggested to look at some of the features of geothermal power and consider a technological complex that will include a compressor, sensors, CPU and data acquisition boards. In such a system it is necessary to ensure maximum power take-off under various external factors. It is suggested to do this through the use of intelligent systems, namely the neural network, and it must be created and trained for a specific result.

The purpose of the study is to develop and integrate a neural network that would have a structure for controlling the power in the compressor power system to ensure maximum efficiency. A neural network can act as a logical device and will support the maximum power point (value) in a system with an alternative energy source.

This article provides an example of the use of a neural network in order to find the value of the maximum power point in a power supply system with a geothermal energy source. One of the main features of the constructed neural network is its structure. The neural network is written in the form of a script code and has a multilayer structure (where the first (input) layer has an activation function - a hyperbolic tangent, and the second (output) layer has one - a linear function).

Also, the work considers already known methods of controlling alternative sources and pumping devices, compressors. After that, it was concluded that the use of artificial intelligence (fuzzy logic or neural networks) will have a certain expediency. It appears as a result of the fact that the networks do not require any additional equipment other than a PC for their work, however they constantly retrain themselves, which subsequently will make it possible to take into account the error.

For successful integration of the neural network into the system, the learning process of the neural netwirk was considered, and the construction itself was performed in the Matlab application package.
