Description

[0001] The invention relates to the technical field of wind power generation, in particular to the design of a wind power control experiment system, and is mainly used in the research of wind power characteristics and power control technology. Background technique [0002] Wind power generation has become one of the important new energy generation methods to solve the energy crisis and promote the sustainable development of new energy. However, the intermittent and random nature of wind energy will lead to fluctuations in the output power of wind farms, which in turn will cause fluctuations in the power grid. Energy storage systems are usually used to regulate fluctuating power to stabilize wind power. Combining different energy storage methods can achieve complementary energy storage characteristics, improve the overall performance of the energy storage system, and reduce the investment and operation costs of the energy storage system. In view of this, this patent proposes a...
