If you want to directly connect a wind power generation device to a power source without a controller, there are a few aspects to consider:

Wind power generation device: Choose a suitable wind power generation device, such as a wind turbine or windmill, to convert wind energy into mechanical or electrical energy.

Power source connection: Directly connect the output of the wind power generation device to the power system. This can be either connecting to the household grid (AC power source) or directly connecting to a battery system (DC power source).

Power source adaptation: Ensure that the output voltage and frequency of the wind power generation device match the requirements of the power system. If necessary, an adapter or converter may be needed to match different power parameters.

However, it's important to note that directly connecting a wind power generation device to a power source without a controller may have some issues:

Stability concerns: Wind energy generation is inherently unstable, depending on factors such as wind speed and direction. This may result in power fluctuations and instability, affecting the reliability of power supply.

Voltage and frequency control: Power systems typically have specific voltage and frequency requirements. If the output voltage and frequency of the wind power generation device do not match the power system, additional controllers or regulating devices may be required to ensure stable and compatible power supply.

Power regulation and distribution: When directly connecting to a power source, power regulation and distribution may need to be considered. This can be achieved through power regulators, battery energy storage systems, or other controllers to ensure power balance and efficient utilization.

In summary, while it is theoretically possible to directly connect a wind power generation device to a power source, in practice, it generally requires appropriate controllers and regulating devices to ensure stability, compatibility, and reliability of power supply. To ensure safety and optimal performance, it is recommended to consult professional engineers or power experts to select the appropriate configuration and control scheme based on specific requirements.
