DER Reliability Scoring for Grid Support Communication Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of distributed energy resources (DERs) into electrical grids faces challenges due to the lack of reliable and secure communication infrastructure, leading to instability and inefficiencies, particularly in supporting grid functions like voltage regulation and frequency management, as existing protocols like IEEE 2030.5 struggle to ensure consistent communication across diverse hardware platforms and networks.
Innovation Solution
The introduction of the Kitu Score system, which assesses the availability and reliability of DERs by monitoring their communication capabilities and performance, providing a value-based incentive for improved communication infrastructure and device reliability, enabling better grid support functions through a cloud-based platform that aggregates data and dispatches control commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If distributed energy resources are integrated into the electrical grid, then renewable energy adoption and greenhouse gas reduction are improved, but grid stability and reliability deteriorate due to bi-directional power flows and communication outages
Solution Approach 1:
The patent implements a feedback mechanism where the platform continuously monitors DER device status, communication availability, and performance metrics. This feedback loop enables the system to assess reliability scores and provide real-time information to utilities and DER owners, allowing for dynamic adjustments to maintain grid stability while accommodating renewable energy integration.
Solution Approach 2:
The patent introduces a communication platform as an intermediary between utilities and DER devices. This intermediary layer manages the complexity of bi-directional communication, coordinates control commands, and handles device monitoring, thereby maintaining grid reliability while enabling widespread DER integration.
2Reliability
If communication infrastructure is enhanced to improve DER coordination, then grid support capability is improved, but system complexity and deployment cost increase
Solution Approach 1:
The patent creates a universal communication platform that can interface with multiple types of DER devices (smart inverters, energy storage systems, electric vehicles) using standardized protocols. This multi-functional platform reduces the need for device-specific communication infrastructure, simplifying deployment while improving coordination capability across diverse hardware platforms.
3Productivity
If real-time control of millions of DER devices is implemented, then grid support services are improved, but communication cost and infrastructure requirements become prohibitive
Solution Approach 1:
The patent implements selective monitoring and control strategies where the platform focuses communication resources on critical DER devices and essential grid support functions. Rather than continuously controlling all millions of DER devices, the system prioritizes devices that provide the most valuable grid support services, reducing communication overhead and costs while maintaining effective grid support delivery.

AI summary
A method of assessing the reliability and availability of a distributed energy resource (DER) device included among a plurality of DER devices in communication with a platform over a network. The method includes monitoring, by the platform, behavior of the DER device. This may include monitoring an extent to which the DER device is available to engage in communication with the platform over the network. This monitoring may also include determining whether the DER device acknowledges control commands sent to the DER device over the network and determining whether the DER executes the control commands in conformance with at least one of a standard and a regulation. The method further includes determining, based upon the monitoring of the behavior of the DER device, a value of a reliability and availability score for the DER device.
