Collective Echo State Networks leverage advanced metering infrastructure (AMI) data for accurate electricity load forecasting. By fully utilizing the correlated meter information from AMI, Collective ESNs can provide accurate predictions for individual power consumption on the single-meter level. This approach overcomes the limitations of traditional methods that treat each meter as a separate univariate prediction task. Collective ESNs offer state-of-the-art prediction accuracy, fast execution speed, and require fewer computational resources.
