Solution Overview
Problem
Existing control systems for facility equipment fail to effectively manage electricity charges 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 within 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 balancing unit prices and predicted usage, including suppression, adjustment, and preliminary operations to avoid exceeding contract demand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If suppression control is applied in high unit price intervals, then electricity charges are reduced, but power usage rebounds in subsequent intervals causing demand value to exceed the greatest value within the relevant period
Solution Approach 1:
The control device performs preliminary operation in intervals immediately prior to high unit price intervals, pre-charging energy storage or pre-adjusting operational states of facility equipment. This allows suppression control to be effectively applied during expensive intervals without causing harmful rebound effects in subsequent intervals that would exceed the reference value
Solution Approach 2:
The control device applies preliminary anti-action by performing preliminary operation that counteracts the anticipated rebound effect. By pre-positioning the system state before suppression control, the device prevents the subsequent power usage surge that would otherwise cause the demand value to exceed the greatest value within the relevant period
2Loss of energy
If suppression control is performed to reduce power usage during high unit price intervals, then power amount charges decrease, but user comfort may deteriorate
Solution Approach 1:
The control device performs preliminary operation in intervals prior to high unit price intervals, storing energy or pre-adjusting facility equipment states. This enables suppression control during expensive periods to be implemented with minimal impact on user comfort, as the preliminary action has already prepared the system to maintain comfort levels despite reduced operation during high price intervals

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.
