Load Operation Scheduling for Dual Power Sale Profit Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control systems for household appliances do not effectively maximize profits from the sale of electric power via both a power generation system and a grid power system, limiting the user's ability to optimize energy usage and revenue generation.
Innovation Solution
A control system that includes a load control unit and a decision unit to determine an operation period where the combined profit from a power generation system and a grid power system is maximized, controlling loads such as electrical water heaters to operate during this period.

Engineering Contradiction Analysis
1Productivity
If the load operates without optimized control, then the operation is simple and convenient, but the profit from power generation system and grid power system is not maximized
Solution Approach 1:
The decision unit calculates and determines the optimal operation period in advance by evaluating forecasted power generation amounts and grid power prices. This preliminary calculation allows the load control unit to execute pre-determined control strategies without real-time complex computations, thereby maximizing profit while keeping the control system manageable.
Solution Approach 2:
The decision unit acts as an intermediary between the load control unit and the external power systems (power generation system and grid power system). It processes information from both systems, evaluates profit potential, and translates complex market conditions into simple operational directives for the load control unit, resolving the contradiction between profit optimization and control simplicity.
2Productivity
If the load operation period is extended to maximize profit, then the profit from power generation system and grid power system increases, but the energy consumption increases
Solution Approach 1:
The decision unit dynamically adjusts the operation period parameters based on changing conditions such as forecasted power generation amounts, grid power prices, and load requirements. By optimizing the start and end times of the operation period, the system maximizes profit during high-value periods while minimizing energy consumption during low-value periods, thereby resolving the contradiction between profit maximization and energy consumption reduction.

AI summary
A control system includes a load control unit and a decision unit. The load control unit is configured to control a load (e.g., electrical water heater) disposed in a facility. The decision unit is configured to decide on an operation period of the load. The decision unit is configured to decide on an operation period during which a sum of a first profit from a sale of electric power transmitted from a power generation system disposed in the facility and a second profit from a sale of electric power transmitted from a grid power system is maximum. The load control unit is configured to control the load such that the load operates during the operation period decided on by the decision unit.
