Machine learning approaches for decentralized volt-VAr control in PV-rich distribution network
Abstract
The increasing integration of renewable energy sources introduces chal- lenges, such as voltage fluctuations in power distribution networks. While optimal Volt/VAr control addresses these issues, it typically depends on computationally intensive centralized optimization and makes real-time implementation challenging. This study explores machine learning tech- niques, including linear regression and multi-layer perceptron (MLP), to approximate centralized optimization outcomes and enable efficient de- centralized reactive power control. Using simulated data from a 141-bus network generated via MATPOWER under various operating conditions, preliminary findings show that linear regression provides limited predic- tive accuracy, whereas MLP models significantly enhance predictive per- formance, improving accuracy by 60–92%.
