Multi-Location Power Priority Control for Interchangeable Energy Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional priority control technologies are designed for single locations and fail to effectively manage power interchange between multiple locations, lacking a systematic approach for determining the order of priority among power sources and load transfer in interconnected power systems.
Innovation Solution
A power management apparatus that determines the order of priority for power supply to a consuming device across multiple locations, considering power generation, storage, commercial sources, and load transfer, using evaluation axes like cost, loss, and disaster backup, and sets priorities accordingly to ensure efficient power distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional priority control technology is applied within a single location, then power efficiency within that location is improved, but the system cannot effectively manage power interchange between multiple locations
Solution Approach 1:
The priority control apparatus is designed to function universally across multiple locations by determining priority orders for power supply sources at a target location within an interconnected power system. The determination unit evaluates multiple controlled objects (power generation unit, power storage unit, commercial power source, and load transfer) based on evaluation axes, enabling the same control mechanism to operate effectively whether at a single location or across multiple interconnected locations.
2Productivity
If priority control is performed based on multiple evaluation axes including load transfer, then power distribution optimization is improved, but control complexity increases
Solution Approach 1:
The control system segments the priority determination process into distinct evaluation axes (cost, loss, disaster backup) and controlled objects (power generation unit, power storage unit, commercial power source, load transfer). The determination unit evaluates each controlled object independently against the evaluation axes, then integrates these evaluations to establish a comprehensive priority order. This segmentation approach manages complexity by breaking down the overall control task into manageable, independent evaluation components.
3Loss of energy
If the system considers load transfer as a controlled object, then power consumption reduction is improved, but the determination of priority order becomes more complex
Solution Approach 1:
The determination unit acts as an intermediary that evaluates load transfer alongside other power supply sources. By treating load transfer as another controlled object subject to the same evaluation axes (cost, loss, disaster backup), the system seamlessly integrates load transfer considerations into the overall priority determination without requiring separate complex determination logic. The priority setting unit then applies the determined priority order uniformly to all controlled objects including load transfer.
