摘要

Abstract

Conditional transmission section limits (C-TSLs) depend on the actual operational state of the power grid

such as commitment status and reserve capacity

exacerbating the computational complexity of the unit commitment problem. To overcome this complexity

this paper proposes a data-model hybrid-driven approach for solving unit commitment problems. Furthermore

a unit commitment prediction algorithm is proposed to reduce the problem scale by fixing a subset of unit commitment variables

thereby eliminating inactive C-TSL intervals. Specifically

the proposed algorithm incorporates a convolutional attention module to perform deep feature extraction and enhancement on time series data

complemented by a multi-head cross-attention mechanism designed to synthesize temporal and non-temporal features. The introduction of attention mechanisms enhances the prediction performance of the proposed algorithm. Numerical results demonstrate that the proposed approach significantly reduces the number of variables and constraints in the unit commitment model

thereby expediting the solution process while maintaining high solution accuracy.
