Solution Overview
Problem
Existing control systems fail to effectively manage electricity charges in facilities and equipment due to fluctuations in power amount charge unit prices and the relationship between predicted power usage and contract demand, leading to increased base fees when demand exceeds the greatest value in a relevant period.
Innovation Solution
A generating device that acquires power amount charge information and power usage data to generate control information for facility equipment, adjusting operations to minimize electricity charges by considering unit price fluctuations and predicted power usage, while avoiding excessive power usage in subsequent intervals.

Engineering Contradiction Analysis
1Ease of operation
If facility equipment operates continuously to maintain comfort levels, then user comfort is preserved, but power usage increases during high unit price intervals
Solution Approach 1:
The system performs preliminary cooling or heating operations in intervals before high unit price intervals to pre-adjust the temperature environment. This allows the facility equipment to reduce or suspend operations during high charge intervals while maintaining comfort levels, thereby reducing power usage during expensive periods without compromising user comfort.
Solution Approach 2:
Instead of continuous operation, the system implements periodic operation patterns that align with unit price fluctuations. Facility equipment operates intensively during low charge intervals and reduces or suspends operation during high charge intervals, achieving both cost savings and comfort maintenance through time-based operational scheduling.

AI summary
[Object] To realize control that, in control of facility equipment, reduces electricity charges, taking into consideration fluctuation in power amount charge unit prices, and also a relation between a prediction value of power usage and a greatest value in a relevant period. [Solution] A control device that generates control information for controlling facility equipment of a consumer includes an information acquisition unit that acquires information of a power amount charge unit price that fluctuates and information of power usage of the consumer, and a control information generating unit that, on the basis of the power amount charge unit price in an object interval that is an interval in which control of the facility equipment is performed and information of power usage of the consumer in an interval after the object interval, generates control information for the facility equipment of the consumer in the object interval.
