AI Technical Summary

Technical Problem

Conventional technologies are unable to rapidly adjust electricity consumption to match the fluctuating output of renewable energy sources and meet the demands of Virtual Power Plants (VPPs, particularly in terms of scale and response speed, and there is a need to efficiently utilize renewable energy sources with unstable output.

Method used

A control device that sets target power values based on requests for power consumption changes and uses load balancing to shift server loads between geographically dispersed locations, incorporating GSLB and live migration, to manage power consumption and generation dynamically.

Benefits of technology

Enables rapid control of power consumption increases and decreases in response to requests, maximizing the use of renewable energy and reducing electricity costs through dynamic load balancing and ancillary equipment control.

Abstract

The system quickly controls the increase or decrease in power consumption in response to requests regarding increases or decreases in power consumption. [Solution] A control device for controlling power consumption in a service provision system that provides services using servers located at multiple geographically dispersed locations, comprising: a target power setting unit that sets a target power value for a location based on any or more of the following: requests for an increase or decrease in power consumption at the location where the server is located, the electricity charges at the location, and the amount of power generated at the location; and a load balancing setting unit that performs load shifting based on the target power value and taking into account the number of requests per unit time between the multiple servers.
