IP Grid Load Management for Settlement-Grade Demand Response Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electric power grid management systems lack real-time measurement and verification capabilities for load shedding, leading to inefficiencies and inaccuracies in demand response programs, and are unable to effectively create operating reserves or track power savings for both customers and utilities, failing to meet regulatory standards.
Innovation Solution
An IP-based power load management system that communicates with distributed power consuming and supplying devices, providing real-time data on state changes, directives, and status updates, transforming this information into settlement-grade data for accurate tracking and settlement purposes, enabling the creation of operating reserves and improving grid stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional one-way RF communication systems are used for demand response, then device control capability is achieved, but real-time measurement and verification of load shedding is lost
Solution Approach 1:
The patent implements a feedback mechanism where smart meters continuously measure and report load shedding data back to the utility system in real-time. This two-way communication enables verification of actual load reduction, providing precise measurement while maintaining manageable system complexity through standardized protocols.
Solution Approach 2:
The smart meter serves multiple functions: it acts as both a billing meter and a measurement device for demand response verification. This multi-functionality consolidates measurement capabilities into existing infrastructure, improving measurement precision without proportionally increasing overall system complexity.
2Measurement precision
If statistical estimations are used for measuring demand response effectiveness, then system simplicity is maintained, but accuracy of power savings tracking deteriorates
Solution Approach 1:
The patent replaces statistical estimation methods with direct electronic measurement and reporting through smart meters. This substitution of measurement methodology provides accurate, real-time data on actual power savings, improving measurement precision while the automated digital reporting maintains processing efficiency.
3Reliability
If historical information is transmitted via smart meters for after-the-fact evidence, then verification capability is provided, but real-time measurement and verification is not achieved
Solution Approach 1:
The smart meter continuously measures and stores load shedding data in real-time before utility verification is needed. This preliminary measurement action ensures that accurate verification data is already available when needed, providing both real-time measurement capability and reliable verification without time loss.
4Measurement precision
If FERC, NERC, and NIST standards are not met, then device simplicity is maintained, but settlement-grade data capability and operating reserve creation are insufficient
Solution Approach 1:
The smart meter is designed to meet multiple regulatory standards (FERC, NERC, NIST) simultaneously through integrated measurement and reporting capabilities. This multi-standard compliance is achieved by consolidating required functions into a single device, improving measurement precision while managing complexity through standardization.
