Abstract
To deal with the unstable stability of output power and the volatility of voltage in the wind power generation, a wind and hydrogen power electric generating system was put forward in the paper to break though the grid-connected bottleneck. In the system, the controllable output, which corresponds to "valley" of the wind power generation output, is used as the guarantee steady output power for the wind power plant, and the uncontrollable output corresponding to the part between "peak" and "valley" is adopting the peak load shifting mode to balance. In the mode, the "peak" is used for hydrogen generation to "cut the peak" and the "valley" is used for electric power generation by hydrogen to "fill the valley" . What is more, as an example, the Rudongfeng Power Plant was introduced to complete corresponding analysis and computation, and the result showed that the system can guarantee the balance of power output mostly and it can be a feasible and effective way to solve the grid-connection of wind power generation.
