WIND-SOLAR POWER PLANT WITH ENERGY STORAGE Russian patent published in 2023 - IPC F03D7/04 H02S10/12 H02J7/04 

FIELD: renewable energy sources.

SUBSTANCE: used for uninterrupted power supply to consumers remote from centralized electrical networks. A wind-solar power plant with energy storage contains a common zero bus for supplying a consumer of DC electrical energy and a potential bus. A load resistor is connected to the potential bus with the first output, the second output of which is connected through the key outputs to the common bus. The potential bus is divided by a diode into the first potential bus, to which the first terminal of the corresponding battery polarity is connected and between which the energy consumer is connected and the common bus, and the second potential bus, between which and the common bus a generator driven by a wind turbine, a solar panel, and a controller battery charging are connected through diodes. The controller includes a circuit of serial first and second resistors, the first output connected to a common bus, forming the first voltage divider, and a stabilized voltage source, to the output of which and the common bus the first and second operational amplifiers and the second voltage divider are connected by power outputs to the third and fourth resistors connected in series. The inverting input of the first operational amplifier is connected to the output of a stabilized voltage source. The inverting input of the second operational amplifier is connected to the connection point of the third and fourth resistors. The non-inverting input and output of the second operational amplifier is connected respectively to the connection point of the first and second resistors and is connected to the control input of the switch, and the output of the first operational amplifier is connected to the LED. The first output of the load resistor is connected to the second potential bus. The battery is connected by the second terminal to the common bus through a resistor. The inverting input of the first operational amplifier is connected to the output of a stabilized voltage source, and the non-inverting input of the second operational amplifier is connected to the second output of the battery. The outputs of the first and second operational amplifiers are connected respectively through the first and second LEDs to the input of the key connected through a resistor to the common output of the key connected to a common bus.

EFFECT: providing a limitation of the battery charge current to increase its service life.
