Energy System Design Using Abstract and Complex Models
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Designing energy systems is inefficient and prone to inconsistencies due to the need to manage multiple tools with varying levels of abstraction, leading to resource wastage and potential mistakes in system sizing and architecture.
Innovation Solution
A computer-implemented method that determines an abstract structure of an energy system using pre-defined abstract models for each component, followed by configuring system sizing based on these models, and then refining to a complex structure using pre-defined complex models to assess performance, allowing for precise energy system design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple tools with varying levels of abstraction are used to design energy systems, then comprehensive system analysis can be performed, but resource wastage and inconsistencies increase
Solution Approach 1:
The design process is segmented into distinct phases: abstract modeling phase for system architecture and sizing, and complex modeling phase for detailed performance analysis. Each phase uses appropriately detailed models, preventing premature complexity while ensuring thorough analysis where needed.
Solution Approach 2:
Abstract models are used in preliminary design stages to establish system architecture and sizing before committing to detailed complex models. This preliminary action allows exploration of multiple configurations efficiently, reducing later redesign work and resource wastage.
2Measurement precision
If multiple tools with varying levels of abstraction are used to design energy systems, then comprehensive system analysis can be performed, but inconsistencies in system sizing and architecture increase
Solution Approach 1:
Abstract models serve as an intermediary layer between different design tools and phases. They provide a common reference framework that ensures consistency when transitioning from abstract sizing to detailed complex modeling, preventing mismatches in system architecture and sizing.
Solution Approach 2:
Instead of building detailed models first and then simplifying, the approach inverts the traditional sequence by starting with abstract models and progressively adding complexity. This ensures that the fundamental system architecture is established correctly before detailed design, maintaining consistency throughout.
3Manufacturing precision
If detailed complex models are used from the beginning, then precise system design can be achieved, but computational resources and time are wasted
Solution Approach 1:
The methodology applies partial modeling - using detailed complex models only for specific components or aspects that require precise analysis, while other parts use simpler abstract models. This selective application of modeling detail maintains design precision where needed while preserving overall design efficiency.
Solution Approach 2:
The modeling approach is dynamic and adaptive - starting with abstract models and progressively transitioning to complex models as the design matures and specific detailed analysis becomes necessary. This dynamic adjustment of model fidelity optimizes both precision and efficiency throughout the design process.
