Application Prospects

The circulating fluidized bed boiler (CFB) power unit with its energy-saving and environmental protection has broad application prospects, but the problem of CFB unit automatic control has not been solved satisfied, so automatic generation control (AGC) can not be stabilized input. Through the improvement of the unit automatic control strategy by the method of intelligent predictive multivariable decoupling control and optimization of parameters, the AGC tests achieved approving results in CFB unit.

With the high degree of wind power penetration integrated into multi-area AC/DC interconnected power grids, the frequency regulation capacity of automatic generation control (AGC) units is not sufficient in the wind power-penetrated area, making it difficult to effectively suppress the frequency stability caused by the fluctuation of wind power. Therefore, a coordinated control strategy for AGC units across areas based on bi-level model predictive control is proposed in this paper to achieve resource sharing. The control scheme uses economic model predictive control to realize steady power optimal allocation of the AGC units across areas in the upper layer and distributed model predictive control to realize dynamic frequency optimization control of the multi-area AGC units in the lower layer. Taking a three-area AC/DC interconnected power grid with a wind farm as an example, the simulation results show that, compared with model predictive control using tie-line frequency bias control (TBC) mode, the proposed control strategy can not only effectively maintain tie-line safety and frequency stability, but can also reduce the regulation cost of multi-area AGC units.
