Energy Storage Balance Control Based on Deterioration Cost
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The introduction of electric storage apparatuses incurs costs and deteriorates over time, leading to potential inefficiencies in power management systems, as existing control methods do not adequately consider the balance between operational benefits and deterioration costs.
Innovation Solution
A power management apparatus and method that compares the effects of operating and not operating electric storage apparatuses, executing balance control only when the operational benefits exceed the deterioration costs, thereby optimizing the utilization of electric storage apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If balance control is continuously executed to maintain demand and supply balance, then power management effectiveness is improved, but electric storage apparatus deterioration accelerates and operational costs increase
Solution Approach 1:
The control method dynamically adjusts the operation strategy of the electric storage apparatus based on real-time comparison between first effects (power balance benefits) and second effects (deterioration costs). The controller transitions between balance control execution and non-execution states, optimizing the trade-off between maintaining demand-supply balance and preserving apparatus lifespan.
Solution Approach 2:
The system changes operational parameters by comparing quantitative effects: when the first effect (power balance achievement) exceeds the second effect (deterioration cost), balance control is executed; otherwise, it is suspended. This parameter-based decision-making optimizes both reliability and durability.
2Productivity
If electric storage apparatus is operated frequently for power management, then power balance control effectiveness is improved, but operational costs and deterioration expenses increase
Solution Approach 1:
The controller continuously monitors and compares the first effect (power balance effectiveness) with the second effect (operational costs and deterioration). This feedback mechanism enables real-time optimization of operation frequency, ensuring the electric storage apparatus operates only when the benefits outweigh the costs.
Solution Approach 2:
The system adjusts operational parameters by comparing quantitative effects: when power balance effectiveness exceeds operational and deterioration costs, the apparatus is operated; otherwise, operation is suspended. This parameter-based approach optimizes productivity while minimizing losses.

AI summary
A power management apparatus includes a manager configured to manage a utilization state of an electric storage apparatus and a controller configured to execute a balance control of the electric storage apparatus such that a power of one or more facilities becomes close to a target power. The controller is configured to compare a first effect and a second effect, the first effect being produced by operating the electric storage apparatus, the second effect being produced by not operating the electric storage apparatus, and not to execute the balance control in a case where the second effect is higher than the first effect, and to execute the balance control in a case where the first effect is higher than the second effect.
