A Method Of Active Power Random Allocation For Power Grid Stability Analysis

Abstract

With the gradual development of artificial intelligence technology in the field of power grid simulation and analysis, in order to overcome the problems of weak typicality of online samples and slow production speed of offline samples, it is necessary to study the automatic sample generation technology. If the unit output is completely random and the data is generated according to the constraint screening method, the screening efficiency is low under the constraint of the total active power sum equation, and the unit output probability density can not be controlled, so it is easy to over fit or under fit. In engineering, two steps are given to realize the generation of active power scheme and the allocation of active power. The allocation scheme satisfying the constraints of total active power and security inequality is generated. Through the mechanism of random allocation of active power and random rotation of units, the distribution of active power of units is ensured to be average. In the active power distribution of multiple units, the effectiveness of the proposed method and the necessity of random rotation of units are proved by the spatial distribution of unit output.
