The ability of absorbing the disturbance of wind power generation has become a bottleneck to the development of the wind power. Because of the lower load response rate

traditional thermal power units cannot meet the requirement. The pipe line

heat exchanger and radiator in the heat supply network of heat supply units have huge capacity of thermal storage

which can be used to improve the load response rate within a short time. Based on the idea of experimental verification

by nonlinear multi scale decomposing of automatic generation control (AGC) load order

the load order of heat supply units is constructed. According to the simplified nonlinear dynamic model of typical heat supply units

the optimization control scheme for units is designed. The scheme can take full advantage of the thermal storage in the heat supply network

which can improve the load response rate of the units drastically and can compensate the stochastic disturbance of wind power generation without the influence on the heat consumer.
