AI Technical Summary

Technical Problem

Existing power system unit combination problems cannot simultaneously achieve high accuracy in time dynamic modeling, spatial structure representation capability, and high computational efficiency. Traditional methods have high computational complexity or low iteration efficiency, which cannot meet the needs of power grid dispatching.

Method used

A unit combination prediction model based on alternating fusion of graph convolutional network (GCN) and Informer network is adopted. By constructing the power grid topology, spatial features are extracted, and temporal features are captured by combining sparse self-attention mechanism. A constraint perception mechanism and dynamic penalty strategy are introduced to optimize unit start-up and shutdown decisions.

Benefits of technology

It improves the computational efficiency and decision-making accuracy of power system unit combination optimization, meets power grid security constraints, and provides an efficient dispatching scheme.
