What is the principle of wind and solar power?

Wind power is generated by the wind blowing the fan blades of the fan. The rotation of the fan blades drives the generator to rotate, and then generates electricity. Solar power generation is when light is irradiated onto a solar panel, and the semiconductor of the solar cell generates current under the photoelectric effect.

Wind power is generally AC, while solar power is DC.

Is the electricity generated by wind turbines DC? Is the waveform a positive dazzle wave?

The frequency and voltage of the wind energy generator are always unchanged. The power and current generated by the blades increase when the blades rotate faster, and the power and current generated when the blades rotate slow down decrease.

Wind energy generators generate alternating current and do not need to be stored when running on the grid. There is more online absorption and less online replenishment. If there is no grid-connected operation, the alternating current should be converted into direct current and stored in the storage battery. The storage battery should then be converted into alternating current for power supply. The storage battery stores the battery when it is long and replenishes the battery when it is short to ensure the user's electricity.

Using battery storage is a helpless move that cannot be connected to the grid. Where conditions permit, it is operated on the grid. Using battery storage increases the cost.

At present, almost all wind turbines are DC, and the grid-connected ones need to be boosted to kilovolts

The off-grid types enter the 380-volt civilian three-phase AC grid

Wind force changes, so the output current and frequency of the generator require equipment to stabilize the current, and it is impossible to output smoothly
