Solution Overview
Problem
Conventional error handling frameworks struggle to manage errors in complex microgrids with multiple devices and types of devices, as they are limited in distinguishing between transient and permanent errors, and in handling multiple errors simultaneously.
Innovation Solution
A modular and flexible error handling framework that measures device attributes, compares them with predetermined thresholds, and generates error signals with a numerical sequence identifying the attribute and device, allowing for simultaneous detection and handling of multiple errors.

Engineering Contradiction Analysis
1Reliability
If conventional error handling frameworks are used in microgrids with multiple devices and types, then the system can operate with simple error detection, but it cannot effectively distinguish between transient and permanent errors or handle multiple errors simultaneously
Solution Approach 1:
The error handling framework is segmented into distinct functional modules: error detection module that identifies errors, error classification module that distinguishes between transient and permanent errors, and error handling module that processes different error types. This segmentation allows the system to handle complex error scenarios while maintaining manageable system architecture.
Solution Approach 2:
The patent implements a universal error handling framework that can detect, classify, and handle multiple types of errors across different device types within a single integrated system. The framework uses a standardized error code structure that works universally across generators, storage devices, loads, and other microgrid components, eliminating the need for separate error handling systems for each device type.
2Productivity
If the error handling framework processes errors sequentially, then the system structure remains simple, but it cannot handle multiple errors simultaneously occurring in the microgrid
Solution Approach 1:
The error handling framework dynamically adapts its processing based on the number and type of errors detected. When multiple errors are present, the system activates parallel processing pathways that can handle multiple error scenarios simultaneously. The framework dynamically generates appropriate error codes and selects suitable handling strategies based on real-time error conditions, enabling flexible response to varying error scenarios.
3Adaptability or versatility
If conventional error handling methods are used, then the implementation remains simple, but the system cannot effectively manage microgrids with widely varying complexity and device types
Solution Approach 1:
The patent implements a universal error handling framework that can detect, classify, and handle multiple types of errors across different device types within a single integrated system. The framework uses a standardized error code structure that works universally across generators, storage devices, loads, and other microgrid components, eliminating the need for separate error handling systems for each device type.
Solution Approach 2:
The error handling framework utilizes parameter-based error codes that can represent different error conditions, device types, and severity levels. By changing the parameters within the error code structure (such as error type, device identifier, severity level), the system can adapt to handle diverse microgrid configurations and device types without requiring fundamental changes to the framework architecture.

AI summary
A method of handling one or more errors in a microgrid includes measuring an attribute of a device within the microgrid for a measurement cycle and comparing the measured attribute of the device with a predetermined threshold attribute value. The presence of an error associated with the device is detected based on the comparison of the measured attribute with the predetermined threshold attribute value. An error signal is created that includes a numerical sequence having at least three digits, the numerical sequence identifying the measured attribute and the device within the microgrid.
