Abstract

Probabilistic net-load forecasting in Low-Voltage (LV) distribution networks is essential in light of the increased variability introduced by the widespread integration of renewable energy sources (RES). Various probabilistic approaches based on neural networks have been proposed to solve this challenge. This study introduces lightweight neural network-based conformal prediction (Conformal-MLPF) for net-load forecasting within an LV power distribution network. It uses Split Conformal prediction to transform a lightweight MLP-based point forecast into a probabilistic forecast. Our validation on two real-life LV substations datasets suggests that the proposed Conformal-MLPF achieves a better tradeoff between forecasting performance and model complexity without requiring restrictive assumptions about data distribution.
