Power Management Server for Feed-In Tariff Expiration Forecasting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing equipment management systems are unable to effectively manage the fluctuation of reverse power flow output from distributed power supplies, such as solar cell and wind power generation, due to the unpredictability of feed-in tariff expiration periods, which affects user behavior and power consumption patterns.
Innovation Solution
A power management system that includes an equipment management apparatus and a power management server, where the equipment management apparatus transmits a message to the power management server specifying the expiration timing of the feed-in tariff period, allowing for better prediction and management of reverse power flow fluctuations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If equipment management systems only target maintenance management, then maintenance functionality is provided, but the ability to predict and manage reverse power flow fluctuations is lost
Solution Approach 1:
The equipment management apparatus is extended to perform multiple functions: it not only manages maintenance information but also acquires feed-in tariff expiration information and transmits it to the power management server. This multi-functional approach enables the system to predict reverse power flow fluctuations while maintaining its core maintenance management capabilities.
2Device complexity
If feed-in tariff expiration timing is not tracked, then system simplicity is maintained, but reverse power flow prediction accuracy deteriorates
Solution Approach 1:
The equipment management apparatus proactively acquires feed-in tariff expiration information in advance and transmits it to the power management server before the actual expiration occurs. This preliminary action enables the power management server to predict reverse power flow fluctuations ahead of time, improving prediction accuracy without requiring complex real-time monitoring systems.

AI summary
A power management system includes a facility including an adjustment power supply to which feed-in tariff is applied. The power management system includes an equipment management apparatus that manages the adjustment power supply, and a power management server that manages a reverse power flow output from the facility to a power grid. The equipment management apparatus includes a transmitter transmitting, to the power management server, a message including an information element with which an expiration timing of a period to which the feed-in tariff is applied is allowed to be specified.
