Microgrid energy optimization scheduling method based on adaptive control

Abstract

The invention relates to a microgrid energy optimization scheduling method based on adaptive control. The microgrid energy optimization scheduling method comprises the steps of S1, obtaining a randomlinear control system; S2, constructing an adaptive microgrid optimization scheduling model according to the random linear control system obtained in the step S1; S3, performing MPC optimal schedulingon the adaptive microgrid optimal scheduling model constructed in the step S2. The beneficial effects of the method are that: according to the microgrid energy optimization scheduling method based onadaptive control, under a combined optimization scheduling framework of a random energy and an energy storage system, an optimization strategy based on adaptive random model predictive control is provided; the method is compared with a robust model predictive control method based on scene construction, different self-adaptive updating strategies and comparison models of different adjusting parameters are designed, the scheduling performance of the system and the self-adaptability of the model can be effectively improved, and the conservative property of the system is reduced.

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...
