Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing use of decentralized energy resources (DERs) behind the meter in electrical consumer networks complicates grid monitoring and stability, as end-user behavior deviates from standard load curves, and devices like PV systems, EV chargers, and battery storage systems are often unregistered or not metered separately, lacking transparency and accurate identification.
Innovation Solution
A method using a higher-level electronic computing device to determine devices downstream of the meter by analyzing net load profiles and weather information, employing mathematical models and machine learning algorithms to identify and disaggregate these devices without additional measurement infrastructure, enabling precise identification and monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If decentralized energy resources are installed behind the meter, then energy autonomy and flexibility are improved, but grid monitoring transparency deteriorates
Solution Approach 1:
The patent introduces an intermediary approach by using weather data (irradiance information) as a mediator to indirectly infer PV system characteristics. Instead of directly measuring behind-the-meter devices, the system uses external weather information combined with net load profiles to deduce device presence and characteristics, thus maintaining monitoring transparency while preserving energy autonomy.
Solution Approach 2:
The patent replaces direct mechanical measurement infrastructure with an information-processing approach. Instead of installing additional physical meters or sensors behind the meter, the system substitutes a computational model that processes net load profiles and weather data to identify devices, eliminating the need for costly physical expansions while maintaining monitoring capabilities.
2Measurement precision
If additional measurement infrastructure is installed to monitor devices behind the meter, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies self-service by utilizing existing net load measurement data and free weather information to achieve device identification. The system serves itself by processing already-available data through mathematical models and machine learning algorithms, eliminating the need for additional measurement infrastructure while maintaining precise device identification capabilities.
Solution Approach 2:
The patent creates a virtual copy of the physical measurement infrastructure through computational models. Instead of physically installing new meters, the system creates a digital representation that processes net load profiles and weather data to infer device characteristics, achieving equivalent measurement precision through information processing rather than physical duplication.
3Ease of operation
If sequential disaggregation approaches are used for different devices, then ease of operation is improved, but measurement precision deteriorates due to simultaneous PV generation interference
Solution Approach 1:
The patent merges multiple disaggregation approaches into a unified simultaneous processing framework. Instead of sequentially analyzing different devices one after another, the system combines PV generation detection, battery storage identification, and EV charging detection into a single integrated analysis that processes net load profiles and weather data concurrently, eliminating interference between detection methods while maintaining operational simplicity.
