System for optimizing the cost of electricity supply, partially obtained from renewable energy sources, and method for optimizing the cost of electricity supply, partially obtained from renewable energy sources

Abstract

The system for optimizing electricity supply costs comprises a line input (1) constituting a connection to the power grid, alternative power sources, such as a solar energy generating device (2a) that converts solar energy into electricity, a gas generator (2b) that burns gas and generates electricity, and a wind generator (2c). The wind generator segment (2c), electrically connected to the control station (3), comprises a main duct connected in a closed-loop system for transporting air within the main duct and at least one segment consisting of at least a radial fan (5) and at least one wind turbine (6). Each wind turbine (6) has its own rotor and at least one permanent magnet generator or generator, wherein the wind turbine rotor (6) is aligned with the wall elements dividing the main duct into smaller channels directing the air flow.The radial fan (5) is placed at the end of the smaller channels.
