Power Grid Reconfiguration Planning Using Load Accommodation Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power system renewal plans often fail to consider the interdependencies between power transmission and distribution systems, leading to inefficient facility management and excessive investment due to a lack of coordination between departments responsible for these systems.
Innovation Solution
A system planning support coordination system that integrates processing devices and storage devices to store and manage information on both power transmission and distribution systems, allowing for the determination of load accommodation capacity and creation of system plan proposals that include configuration changes in both systems, ensuring a holistic approach to power system planning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If facility renewal plans are formulated separately by each department (power transmission and power distribution), then departmental planning simplicity is improved, but system-wide optimization deteriorates
Solution Approach 1:
The patent merges the previously separate power transmission system planning and power distribution system planning into a unified system plan. The planning support device integrates both systems to evaluate facility discontinuance candidates comprehensively, ensuring that decisions consider impacts on both transmission and distribution sides simultaneously, thus achieving system-wide optimization while maintaining manageable planning processes.
2Loss of time
If facility discontinuance decisions are made without considering the other system, then decision-making speed is improved, but decision accuracy deteriorates
Solution Approach 1:
The planning support device performs preliminary evaluation of facility discontinuance candidates by assessing both the power transmission system side effects and power distribution system side effects before final decision-making. This preliminary comprehensive evaluation ensures accurate decisions while maintaining efficient timelines, as the system pre-calculates impacts on both sides rather than requiring sequential separate evaluations.
3Ease of manufacture
If system configuration changes are made without evaluating load accommodation capacity, then implementation simplicity is improved, but system reliability deteriorates
Solution Approach 1:
The planning support device incorporates feedback mechanisms that evaluate load accommodation capacity before approving system configuration changes. The system assesses whether the power distribution system can accommodate loads if a facility is discontinued, and uses this feedback to determine if discontinuance is feasible. This ensures reliable decision-making while maintaining straightforward implementation processes.

AI summary
Disclosed is a system for supporting creation of a system plan to change a configuration of a power system including a power transmission system and a power distribution system. The system stores information on a configuration of the power transmission system and information on a configuration and a load of the power distribution system. The system determines, based on the information on the configuration and the load of the power distribution system, a load accommodation capacity between power distribution substations which indicates a power supply capacity allowed to be compensated for between the power distribution substations through a configuration change of the power distribution system. The system creates a system plan proposal including a change in system configuration of the power transmission system and the power distribution system based on the load accommodation capacity. The system outputs information on the system plan proposal to an output device.
