Microgrid Power Incentives for Precise Demand Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power management systems face challenges in appropriately managing power demand and supply due to insufficient conformity of power adjustment resources to requests, leading to deviations in power amounts.
Innovation Solution
A power management system that includes a server managing power adjustment resources, which provides incentives based on the deviation from requested power amounts to encourage precise power adjustments, using vehicles as power adjustment resources for charging and power feeding.

Engineering Contradiction Analysis
1Reliability
If a power adjustment request is output to power adjustment resources, then power adjustment is performed, but the response may not sufficiently conform to the request leading to deviation in power amounts
Solution Approach 1:
The server calculates the deviation between the requested power amount and the actual adjusted power amount, and uses this feedback to determine the incentive level. This feedback mechanism ensures that resources are motivated to minimize deviation and improve conformity to requests.
Solution Approach 2:
The incentive amount is dynamically changed based on the deviation parameter. When deviation is within a threshold, a standard incentive is provided; when deviation exceeds the threshold, the incentive is reduced. This parameter-based adjustment motivates resources to improve their response precision.
2Productivity
If incentive is given to power adjustment resources, then motivation to respond is increased, but incentive cost increases for the system operator
Solution Approach 1:
The incentive is not uniformly applied to all power adjustment resources, but is locally adjusted based on each resource's performance in meeting the requested power amount. Resources that achieve better conformity receive higher incentives, while those with larger deviations receive reduced incentives.
Solution Approach 2:
The system applies a threshold-based incentive structure where full incentive is given only when deviation is within acceptable limits. This partial action approach ensures that incentives are spent efficiently only when they achieve the desired power adjustment outcome.

AI summary
A power management system includes a plurality of power adjustment resources electrically connected to a microgrid MG, and a CEMS server that manages the power adjustment resources. The CEMS server outputs a power adjustment request to a plurality of power adjustment resources when suppression of power consumption or consumption of surplus power is requested in the microgrid MG, and gives an incentive to the power adjustment resource that performs power adjustment in response to the power adjustment request among the power adjustment resources. The CEMS server increases the incentive more as a deviation of a second power amount adjusted by a responding resource with respect to a first power amount requested for adjustment by the power adjustment request is smaller.
