Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Open Automated Demand Response (OADR) systems face challenges in implementing secure and cost-effective internet connections for energy market signal communications, and they lack the ability to provide customers with direct access to meter data for managing energy consumption.
Innovation Solution
An OADR endpoint device that translates market signals into actionable formats for energy management, includes secure communication protocols, and allows facility managers to access and monitor meter data, using a processor to facilitate message processing and control energy devices based on market prices and consumption data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If internet connections are implemented for OADR communications, then energy market signal transmission is enabled, but implementation difficulty and operating costs increase
Solution Approach 1:
The patent introduces an OADR gateway as an intermediary device that bridges the energy management system and the OADR network. This gateway handles the complexity of internet connectivity, protocol translation, and secure communication, allowing the internal energy management system to remain simple while still enabling sophisticated energy market signal transmission and demand response capabilities.
2Adaptability or versatility
If internet connections are implemented for OADR communications, then energy market signal transmission is enabled, but operating costs increase
Solution Approach 1:
The OADR gateway implements self-service capabilities by automatically managing connection establishment, maintaining persistent connections to reduce reconnection overhead, and optimizing data transmission timing. The system autonomously handles authentication, session management, and adaptive data polling, eliminating the need for manual intervention and reducing operational costs while enabling continuous energy market signal transmission.
3Reliability
If data transmission over internet is avoided, then security is improved, but access to energy market signals is limited
Solution Approach 1:
The OADR gateway serves as a secure intermediary that isolates the internal energy management network from direct internet exposure. It implements security measures including authentication, encryption, and controlled data filtering, allowing the system to access energy market signals and demand response events while maintaining network security and preventing unauthorized access to internal systems.
4Ease of operation
If customer access to meter data is provided, then energy management capability is improved, but system complexity increases
Solution Approach 1:
The system implements self-service energy management capabilities by providing customers with direct access to their meter data and consumption information through the OADR gateway. Customers can monitor their energy usage, receive demand response events, and make informed decisions about load management without requiring complex manual interfaces or constant vendor intervention, thereby improving ease of operation while keeping the system architecture relatively simple.

AI summary
Implementations of the disclosure describe an Open Automated Demand Response (OADR) endpoint device. A method of the disclosure includes receiving, by a processing device of an endpoint device, a first message comprising a first market energy price, determining whether a first quantity of energy has been consumed within a first time period by at least one energy device associated with the endpoint device, responsive to a determination that the first quantity of energy has been consumed by the at least one energy device within the first time period, determining whether the first market energy price is greater than a price threshold and responsive to a determination that the first market energy price is greater than the price threshold, causing the at least one energy device to stop consuming additional amounts of energy.
