The invention discloses a hybrid energy storage smooth wind power control system with variable filter coefficients. The control system comprises a signal measuring and acquiring unit, a signal transmission unit, a variable-coefficient filter, a power divider, a super-capacitor energy storage system and a storage battery energy storage system. distribution of compensation power in energy storage units is optimized by changing filter coefficients of a filter, fluctuating wind power is processed by the variable-coefficient filter and the power divider to obtain a power value required to be compensated by the storage battery energy storage system and the super-capacitor energy storage system, and the energy storage systems adopt a PQ control output to compensate the power and feed the power back to a power grid so as to achieve the purpose of smoothing fluctuating power. The hybrid energy storage smooth wind power control system meets the requirement for smooth wind power output, reduces discharging depth of storage batteries, prolongs the service life of the storage batteries and enables the utilization rate of super-capacitor energy storage devices to be improved.
