Disaggregating Energy Consumption: The NILM Algorithms Behind Akeptus and Point80

In the era of intelligent energy management, the quest to monitor and control energy consumption has never been more crucial. One of the groundbreaking innovations at the forefront of this revolution is the implementation of Non-Intrusive Load Monitoring (NILM) algorithms by platforms like Akeptus and Point80. In this blog post, we will explore the intricacies of these algorithms and how they facilitate appliance-level energy tracking.

What is NILM?

Non-Intrusive Load Monitoring (NILM) is a technology that breaks down the total energy consumption of a building into individual appliance-level usage. Unlike traditional methods that require separate meters for each appliance, NILM works with just a single meter, making it a more cost-effective and less intrusive solution.

The Challenge of Energy Disaggregation

Energy consumption analysis at the appliance level is vital for identifying inefficiencies, reducing costs, and improving sustainability. However, conventional methods often involve complex installations, high costs, and potential privacy concerns. NILM addresses these challenges by providing detailed insights without the need for individual submetering.

NILM Algorithms Behind Akeptus

Akeptus employs a combination of state-of-the-art algorithms, including wavelet transformations and deep learning models. These algorithms work synergistically to analyze voltage and current waveforms, offering a precise understanding of energy consumption patterns. Here’s how:

1. Data Collection and Preprocessing: Akeptus collects high-frequency voltage and current waveforms from a single meter. The data is then preprocessed to filter out noise and prepare it for analysis.

2. Feature Extraction and Identification: By analyzing the waveform changes, Akeptus’s patented NILM algorithms extract features that are unique to different appliances. This allows the system to identify and track individual devices within a home.

3. Machine Learning and Pattern Recognition: Machine learning models are trained to recognize these unique patterns, enabling the system to differentiate between various appliances and estimate their individual energy consumption.

4. Real-Time Monitoring and Automation: Akeptus provides real-time visibility into appliance-level usage and can even automate home energy management. This includes scheduling lights and appliances to turn on and off at certain times, or modulating HVAC systems to flatten peak demand.
