Abstract

The present invention relates to a micro-grid energy optimal scheduling method based on adaptive control, comprising: S1, acquiring a random linear control system; S2, constructing an adaptive micro-grid optimal scheduling model according to the random linear control system acquired in step S1; S3, pairing The adaptive microgrid optimal scheduling model constructed in step S2 performs MPC optimal scheduling. The beneficial effect of the present invention is: the microgrid energy optimal scheduling method based on adaptive control provided by the present invention proposes an optimization strategy based on adaptive stochastic model predictive control under the joint optimal scheduling framework of stochastic energy and energy storage systems , and compared with the robust model predictive control method based on scene construction, and designed a comparison model of different adaptive update strategies and different adjustment parameters, the method proposed in the present invention can effectively improve the scheduling performance of the system and the adaptability of the model , reducing the conservatism of the system.

Description

technical field [0001] The invention belongs to the technical field of microgrids, and in particular relates to an adaptive control-based microgrid energy optimization scheduling method. Background technique [0002] Clean and low-carbon has become the development trend of global energy transformation. The energy revolution characterized by the deep integration of new energy and information technology is pushing human society into a new energy system. A series of problems such as source-load imbalance, as of the end of 2018, my country's solar and wind energy grid-connected installed capacity reached 360 million KW, accounting for 19% of the installed capacity, but the power generation accounted for only 7.8% of the total, and the problem of wind and solar abandonment is still serious. The proposal of the concept of Energy Internet has become a good solution to the above problems and the key to energy transformation. System, EIS) constructed organic cells. [0003] The micr...
