Automated Demand Response Normalization Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Energy management and control systems face challenges in implementing automated demand response due to disparate communication protocols and data formats used by various electricity providers, independent system operators, and aggregators, leading to increased complexity and cost in deploying demand response strategies across multi-site enterprises.
Innovation Solution
The implementation of an automated demand response service with a processing engine for each unique protocol or data format, normalizing event data into a standard format to enable pre-programmed demand response strategies that can be deployed across an entire multi-site enterprise without the need for customization, and the use of an auto DR gateway to manage event distribution and reduce network vulnerabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a processing engine is created for each unique protocol or data format, then the system can support multiple auto DR systems, but the device complexity increases
Solution Approach 1:
The patent implements a universal normalization service that receives event data from multiple automated demand response systems using different protocols and data formats, normalizes this diverse data into a standard format, and delivers it to the energy management system. This single multi-functional service replaces the need for separate processing engines for each protocol, thereby supporting multiple auto DR systems while avoiding the complexity of maintaining multiple specialized engines.
2Adaptability or versatility
If demand response strategies are customized for each site, then local requirements are met, but the development and maintenance costs increase
Solution Approach 1:
The patent implements pre-programmed demand response strategies that are developed in advance using normalized event data from the normalization service. These standardized strategies can be deployed across multiple sites without customization, as the normalization service has already adapted the incoming data to match the expected format. This preliminary normalization action eliminates the need for site-specific strategy customization, significantly reducing development and maintenance costs while still meeting local requirements through the flexibility of the standard strategies.
3Reliability
If event data are not normalized, then data integrity is maintained, but the ease of operation decreases
Solution Approach 1:
The patent introduces a normalization service as an intermediary component between the automated demand response systems and the energy management system. This service receives raw event data from various sources, normalizes it into a standard format while preserving data integrity through validation, and delivers the normalized data to the EMS. This intermediary approach maintains data integrity by implementing proper validation and transformation rules, while simultaneously improving ease of operation by providing the EMS with consistently formatted data that simplifies strategy deployment across all sites.
Data Source
AI summary
An approach for normalizing automated demand response events in energy management and control systems. The normalizing may be of events having disparate communication protocols and data formats. There may be a processing engine for each unique protocol or data format. When event data are received, they may be normalized into a standard format which can be utilized by an energy management and control system to initiate a pre-programmed demand response strategy. In other words, using an auto demand response service with its normalized event information, standard response strategies may be developed. The auto demand response service and standard strategies may then be deployed across an entire multi-site enterprise regardless of the auto demand response service provider servicing a particular site. There appears no need to modify the demand response strategy because the auto demand response service may handle a transformation of the auto demand response system's event data.
