Electricity Wheeling Control Apparatus Partner Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electricity wheeling apparatuses struggle to determine appropriate negotiation partners and manage electricity wheeling between multiple customers, especially when both excess and deficiency situations arise, leading to inefficiencies in electricity distribution.
Innovation Solution
An electricity wheeling control apparatus that includes a wheeling request generator, a wheeling necessity determiner, a negotiation partner determiner, and a wheeling plan determiner, which calculates and negotiates electricity allocation based on operation plans and wheeling capacity values among multiple customers to facilitate efficient electricity distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an electricity wheeling apparatus sends wheeling requests to multiple electricity customers upon occurrence of electricity deficiency, then the ability to find potential wheeling partners is improved, but the capability to determine the appropriate negotiation partner deteriorates when multiple customers respond
Solution Approach 1:
The patent implements a feedback mechanism where electricity customers send wheeling necessity values back to the requesting customer. The negotiation partner is determined based on this feedback information, allowing the system to identify the most appropriate partner among multiple respondents. This resolves the contradiction by using feedback to transform the complexity of multiple responses into a clear selection criterion.
2Device complexity
If an electricity wheeling apparatus only operates upon occurrence of electricity deficiency, then the system simplicity is maintained, but the capability to perform electricity wheeling in excess electricity situations deteriorates
Solution Approach 1:
The patent makes the electricity wheeling apparatus universal by enabling it to operate in both electricity deficiency and excess electricity situations. The same basic mechanism of sending wheeling requests and determining negotiation partners is applied regardless of whether the initiating customer has excess or deficiency, allowing the system to handle multiple scenarios without requiring separate specialized systems.
3Device complexity
If electricity wheeling is performed without calculating wheeling necessity values, then the calculation complexity is reduced, but the accuracy of determining appropriate wheeling partners deteriorates
Solution Approach 1:
The patent introduces wheeling necessity values as an intermediary metric that mediates between the simple act of sending wheeling requests and the accurate determination of negotiation partners. This intermediary value provides a quantitative basis for partner selection without requiring complex direct optimization calculations, resolving the contradiction by using a intermediate measurement to guide the selection process.

AI summary
An energy management system in an electricity customer possessing a distributed power supply includes a wheeling request generator that generates a wheeling request including a wheeling request amount, a wheeling necessity determiner that calculates a wheeling necessity value, a transmitter-receiver that sends the wheeling request amount and the wheeling necessity value to another energy management system, a wheeling negotiation partner determiner that determines at least one wheeling negotiation partner on the basis of wheeling necessity values received, a wheeling response determiner that calculates a wheeling capacity value for the at least one negotiation partner on the basis of the wheeling request amount received, and sends the wheeling capacity value via the transmitter-receiver, and a wheeling plan determiner that determines a wheeling plan on the basis of the wheeling capacity value received and on the basis of the wheeling request amount of that customer itself.
