Keywords:
Hybrid evolutionary algorithms, multi-objective optimization, energy systems, smart grids, renewable integration, computational intelligence, system resilience, distributed optimizationAbstract
Modern energy systems are undergoing a profound transformation driven by increasing penetration of renewable energy resources, decentralization of generation assets, and the integration of advanced information and communication technologies. These transitions introduce significant complexity into system planning and operational decision-making, particularly due to competing objectives such as cost minimization, carbon emission reduction, reliability enhancement, and resilience against disruptions. Traditional optimization techniques often struggle to address such high-dimensional, nonlinear, and conflicting objective spaces. In response, hybrid evolutionary algorithms have emerged as a powerful class of computational approaches capable of exploring large solution spaces while maintaining flexibility in handling multi-objective trade-offs. This paper presents a comprehensive systems-level examination of hybrid evolutionary algorithms for multi-objective optimization in energy systems. It synthesizes methodological advancements in evolutionary computation with domain-specific requirements in modern energy infrastructures, including power grids, distributed energy resources, microgrids, and smart grid architectures. The discussion emphasizes architectural design considerations, algorithmic hybridization strategies, and the integration of domain knowledge into evolutionary search processes. Particular attention is given to the interplay between optimization performance and system-level constraints such as regulatory compliance, fairness in energy distribution, and operational robustness under uncertainty. Beyond algorithmic development, this work explores governance and deployment implications of adopting hybrid evolutionary frameworks in real-world energy systems. It highlights how these approaches can support decision-making in long-term planning, real-time dispatch, and adaptive control environments. The paper concludes by identifying emerging challenges in scalability, interpretability, and integration with data-driven predictive models, positioning hybrid evolutionary optimization as a foundational tool for next-generation sustainable energy infrastructures.
