EV Power Control Scheduling With Pre-Check Communication Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical power systems, such as those described in Japanese Unexamined Patent Application Publication No. 2020-156149, face challenges in reliably adjusting demand and supply of electric power due to consumers' inability to perform charge and discharge within agreed time periods, leading to unsatisfied power control requests.
Innovation Solution
A server system that acquires information on power control periods and determines communication status and operational readiness of electrified vehicles, executing command control for power control only when no abnormalities are found, allowing these vehicles to perform power supply or charge within specified time frames, thereby ensuring reliable demand and supply adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the server schedules power control for electrified vehicles in agreed time periods, then the demand and supply of electric power can be adjusted, but consumers may not be able to perform charge and discharge as scheduled, leading to unsatisfied power control requests
Solution Approach 1:
The server performs preliminary determination of communication status and power control permission status before the scheduled power control time period. This advance verification ensures that only electrified vehicles capable of executing power control are selected, preventing scheduling failures and improving reliability without adding complex real-time monitoring systems.
2Reliability
If the server determines communication status and power control permission for all electrified vehicles before the first time period, then power control reliability is improved, but communication load on the server increases
Solution Approach 1:
The server divides electrified vehicles into multiple groups and performs determination of communication status and power control permission for each group in different second time periods before their respective first time periods. This segmentation distributes the communication load over time, preventing server overload while maintaining reliable power control execution for each vehicle group.
3Productivity
If multiple electrified vehicles perform power control in the same first time period, then the demand and supply adjustment capability is enhanced, but simultaneous determination of communication status creates communication congestion
Solution Approach 1:
The server segments multiple electrified vehicles into different groups, each with different first time periods for power control. This allows the system to maintain high power control capacity by utilizing multiple vehicles while avoiding communication congestion by staggering the determination timing for each group, thus resolving the conflict between productivity and communication load.

AI summary
A server (100; 300) configured to manage power control including at least one of power supply from an electrified vehicle (10) to an electric power system (PG) and charge from the electric power system (PG) to the electrified vehicle (10) includes an acquisition unit (103; 303) configured to acquire information on a first time period in which the power control is performed by the electrified vehicle (10) that has acceded to a request to perform the power control, and a processor (101; 301) configured to determine, in a second time period before the first time period, whether there is an abnormality on at least one of a communication status of the electrified vehicle (10) and whether the power control is allowed to be performed by the electrified vehicle (10). The processor (101; 301) is configured to, when the processor (101; 301) determines that there is no abnormality, execute command control such that the power control is performed by the electrified vehicle (10) in the first time period.
