Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods struggle to maintain a stable balance between power supply and demand, particularly with renewable energy sources like photovoltaic and wind power, as they face difficulties in controlling power generation, leading to challenges in setting appropriate demand schedules for electric vehicles and other power-consuming bodies.
Innovation Solution
An information processing apparatus that sets operation startable and end target time points, determines necessary operation times, and adjusts power demand transition information to match assumed power supply shapes, ensuring a stable balance between supply and demand by optimizing the operation schedules of power-consuming bodies like electric vehicle charging stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large demand target is set for power-consuming bodies, then the capability to stabilize balance between supply and demand is improved, but the number of electric vehicles available for charging becomes insufficient to secure required electrical energy
Solution Approach 1:
The system performs advance prediction of power supply amounts from renewable energy sources and pre-determines optimal charging schedules for electric vehicles. By calculating necessary operation times and setting operation windows before the actual charging period, the system ensures that sufficient electrical energy is secured while maintaining supply-demand balance stability.
Solution Approach 2:
The system dynamically adjusts the demand schedule by optimizing the necessary operation time for each power-consuming body within its operation window. Instead of fixed scheduling, the system flexibly determines the optimal duration and timing of charging operations based on predicted power supply characteristics, allowing adaptation to varying renewable energy generation patterns.
2Quantity of substance
If a small demand target is set for power-consuming bodies, then the electrical energy availability is improved, but the capability to stabilize balance between supply and demand is reduced
Solution Approach 1:
The system changes the parameter of demand scheduling from fixed arbitrary values to optimized time-based parameters. By predicting power supply amounts and calculating necessary operation times, the system transforms the demand target into a dynamic parameter that adapts to actual renewable energy generation, ensuring both energy availability and supply-demand balance.
3Adaptability or versatility
If arbitrary demand targets are set without considering operation time constraints, then the scheduling flexibility is improved, but the feasibility of achieving demand targets becomes insufficient
Solution Approach 1:
The system performs preliminary calculation of necessary operation time for each power-consuming body based on the required electrical energy amount and predicted power supply characteristics. By determining this constraint before scheduling, the system ensures that arbitrary demand targets are paired with feasible operation time requirements, making target achievement reliable while maintaining scheduling flexibility within the operation window.

A time point range setting unit (110) sets an operation startable time point when an operation is startable, and an operation end target time point which is a latest time point among time points when the operation is to be ended, with respect to each of plural power-consuming bodies (20). A necessary operation time setting unit (120) sets a necessary operation time with respect to each of the plural power-consuming bodies (20). A shape information obtaining unit (130) obtains shape information from a schedule management apparatus (40). The shape information represents an assumed shape of a transition line indicating transition in the amount of power supplied in a target period. A demand transition setting unit (140) determines power demand transition information indicating transition in electrical energy demand in the target period so that the necessary operation time is obtained and the transition in the electrical energy demand generated by the plural power-consuming bodies (20) being operated follows the assumed shape.
