OADR Endpoint Gateway for Secure Price-Based Load Shedding
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 communication, and they lack features to allow customers to access and manage their meter data directly.
Innovation Solution
An OADR endpoint device that translates market signals into actionable formats for energy management, includes secure communication protocols, and allows customers to manage energy devices by receiving market prices and consumption data, enabling load shedding and demand charge avoidance through local processing and secure internet connections.
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 cost increase
Solution Approach 1:
The patent introduces an OADR gateway as an intermediary device that bridges the energy market signal transmission between the utility system and customer premises equipment. The gateway handles the complex internet connection requirements and protocol translations, shielding end users from implementation complexity while enabling standardized OADR communications over IP networks.
2Adaptability or versatility
If internet connections are implemented for OADR communications, then energy market signal transmission is enabled, but operating cost increases
Solution Approach 1:
The OADR endpoint device incorporates built-in intelligence to autonomously process energy market signals and execute demand response actions without requiring continuous cloud connectivity or expensive external service intermediaries. The device can locally interpret pricing signals and automatically control connected energy-consuming devices, eliminating ongoing operating costs associated with external management services.
3Adaptability or versatility
If data transmission over internet is required, then OADR standard compliance is achieved, but data security concerns arise
Solution Approach 1:
The patent segments the OADR system into multiple isolated components: the utility-side OADR server, the customer-premises OADR endpoint device, and local energy-consuming devices. Each segment operates with defined communication interfaces and data access permissions. The endpoint device can process and act on energy market signals locally without requiring continuous external connectivity, thereby isolating sensitive customer data from internet-based security threats while maintaining OADR standard compliance.

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.
