Application

Design takeaway

When designing hybrid renewable energy systems, prioritize multi-objective optimization that balances economic viability with environmental sustainability and social impact, and explore advanced AI and metaheuristic techniques while being mindful of their limitations.

How to apply

When developing a new energy system, explicitly define and quantify economic, environmental, and social objectives. Utilize multi-objective optimization algorithms and consider the integration of emerging technologies like hydrogen storage or V2G, while planning for validation and real-world testing.

Project actions

  • 01Clearly define all objectives (economic, environmental, social) for your design project.
  • 02Research and consider using multi-objective optimization techniques if your project involves complex trade-offs.
  • 03Investigate how emerging technologies can be integrated and what their broader impacts might be.

Method & Evidence

AimWhat are the critical research gaps and future prospects for optimizing hybrid renewable energy systems, particularly concerning the integration of multi-objective criteria?
MethodSystematic Review
ProcedureA systematic review of literature from 2015-2025 was conducted using PRISMA 2020 guidelines, analyzing research from Scopus, IEEE Xplore, and Web of Science. The review focused on architectures, mathematical formulations, objectives, and solution methodologies for hybrid renewable energy systems.
ContextHybrid Renewable Energy Systems (HRES) design and operation

Variables

IVOptimization objectives (single vs. multi-objective, types of criteria)
DVSystem performance metrics (economic, technical, environmental, social)
CVSystem architecture, resource availability, solution methodologies

Strengths & Limitations

Strengths

  • +Comprehensive literature coverage (2015-2025).
  • +Adherence to PRISMA 2020 guidelines for systematic review.

Limitations

The complexity of real-world implementation and the difficulty in quantifying social and environmental impacts can be significant limitations for student projects.

Reliability & validity

The reliability of the review is enhanced by the systematic methodology (PRISMA 2020) and the use of multiple reputable databases. Validity is supported by the comprehensive scope of the analysis covering key aspects of HRES optimization.

Think critically

How can designers effectively balance potentially conflicting economic, environmental, and social objectives in the design of complex systems, and what methodologies are best suited for this?

05

Design Principles

"Holistic system design requires the integration of diverse objectives, including economic, environmental, social, and resilience factors, to achieve truly sustainable solutions."

This evolution reflects a growing demand for sustainable and socially responsible design. Designers and engineers must now integrate a broader set of objectives, including environmental footprint and societal benefits, into their optimization strategies for complex systems.

06

What This Means for Your Design

When designing systems that use multiple types of renewable energy, it's not just about making them cheap and efficient anymore. Designers now have to think about how these systems affect the environment and society too.

How to use in your project

  • 1.Cite this review to support the importance of considering multiple objectives beyond just technical performance in your design project.
  • 2.Use the identified research gaps to justify areas where your own design project can contribute novel solutions or explore under-researched aspects.
