Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power grid companies face challenges in detecting conflicts between outage requests and power supply guarantee requests due to the complexity of grid topology and the manual nature of existing detection methods, which can lead to time-consuming and unreliable conflict identification.
Innovation Solution
A system that utilizes geographic and topology information to determine the scope of outages and detect conflicts between outage requests and power supply guarantee requests, including an accompanying outage analysis device, an outage scale determination device, and a conflict detection device to automatically assess potential conflicts and adjust operating modes to avoid them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual conflict detection methods are used, then simplicity of implementation is maintained, but detection reliability and efficiency deteriorate due to time-consuming and error-prone manual processes
Solution Approach 1:
The patent replaces manual mechanical conflict detection with an automated computer-based system that uses geographic information systems and topology analysis algorithms to automatically identify conflicts between outage requests and power supply guarantee requests, eliminating human error and improving reliability
Solution Approach 2:
The patent introduces an intermediary conflict detection system that acts as a mediator between outage request management and power supply guarantee management, using geographic and topology information as intermediate data layers to automatically identify and flag potential conflicts before they occur
2Productivity
If automated conflict detection system is implemented, then detection efficiency and reliability are improved, but system complexity increases due to integration of geographic and topology information systems
Solution Approach 1:
The patent creates a multi-functional integrated system that simultaneously handles geographic information management, topology analysis, outage request processing, and power supply guarantee monitoring, allowing a single system to perform multiple functions that would otherwise require separate systems
Solution Approach 2:
The patent segments the complex detection system into distinct functional modules including geographic information processing, topology analysis, conflict detection algorithms, and user interface components, making the overall system more manageable and easier to implement despite its complexity
3Measurement precision
If comprehensive topology analysis is performed to identify all affected devices, then conflict detection accuracy is improved, but computational time and processing complexity increase
Solution Approach 1:
The patent performs preliminary actions by pre-building and storing geographic information and topology relationships in database structures before conflict detection is needed, so that when conflicts need to be detected, the system can quickly query pre-processed data rather than performing full topology analysis from scratch
Solution Approach 2:
The patent implements dynamic detection strategies that adapt the level of analysis based on the specific situation, performing comprehensive topology analysis only when necessary while using faster approximation methods for routine checks, thereby balancing accuracy with processing time

AI summary
A system for detecting conflicts between a power supply guarantee request (PSGR) and an outage request (OR) in a power grid. The system comprises: an accompanying outage analysis device for receiving a first outage device set including OR related devices, and using geographic information about devices in the power grid to determine a second outage device set, the second outage device set including devices in the first outage device set and accompanying outage devices that need to be in outage together with the devices in the first outage device set; an outage scale determination device for using topology information about the power grid to determine a power grid outage scale in which all of the devices in the second outage device set can be in outage; and a conflict detection device for receiving a power supply guarantee device set including PSGR related devices, and judging, for each device in the power supply guarantee device set, whether the device is included in the power grid outage scale.
