Background

The transition to renewable energy has gained momentum, evidenced by a 5.4% increase in renewable electricity generation in 2021. Despite significant strides, challenges such as the intermittency of wind and solar power persist, complicating grid stability. Previous studies have explored various optimization techniques and machine learning (ML) applications to address these issues, yet gaps remain in effectively integrating MH algorithms with DL for energy optimization.

This study aimed to fill these gaps by offering a comprehensive overview of recent advancements in MH and DL from 2018 to 2023. It introduced the Alpha metric for performance evaluation and proposed an innovative framework that synergized MH with DL, enhancing predictive accuracy and optimization efficiency in energy applications. This research advanced the understanding and application of these methodologies, paving the way for more efficient energy management strategies.

MH for Energy Applications

MH are versatile optimization methods used for complex problems where exact solutions are impractical. They were gradient-free, easy to implement, and often outperformed classical methods. Recent advancements included algorithms like Laying Chicken, Big Bang, Multiverse, and others. These algorithms enhanced deep neural networks by optimizing weight initialization, hyperparameter tuning, and architecture search. MH techniques had been applied to energy-related scenarios, addressing issues like small hydropower planning and power system flexibility.

Integrating DL for Advanced Energy Applications

DL, a subset of ML, leveraged multi-layer neural networks to interpret data. Key breakthroughs like recurrent neural networks (RNNs), convolutional neural networks (CNNs), and long short-term memory (LSTM) networks excelled in processing sequential data, image recognition, and long-term dependencies, respectively.

Recent advancements combined DL with MH algorithms for enhanced energy applications, including load prediction and fault identification. Notable MH algorithms included the enhanced butterfly optimization algorithm (EABOA), modified manta ray optimization (MMRO), and tunicate swarm algorithm (TSA). These algorithms optimized tasks like energy management and control in photovoltaic (PV) systems, hybrid power systems, electric vehicles, and smart grids. DL techniques, including CNNs, RNNs, LSTMs, and transformer models, were applied to smart grid operations, renewable energy forecasting, and load forecasting. These methods improved accuracy and optimized energy systems, enhancing grid security and performance.

MH in DL for Energy Solutions

MH algorithms optimized DL model parameters, improving tasks like cyber threat detection, energy forecasting, and smart grid stability prediction. Notable approaches included reptile search algorithm (RSA) for LSTM models, sine cosine algorithm (SCA) for hyperparameter tuning in LSTM and gated recurrent unit (GRU) networks, and multi-versus optimizer (MVO) for cyber threat detection in smart cities.

Additionally, innovative combinations like jellyfish search (JS) with DL improved short-term electric load forecasting accuracy. Hybrid algorithms, merging MH and ML, optimized building energy systems and wind turbine controller designs. These advancements promised more efficient energy management and facilitated seamless integration of renewable energy sources into grids, contributing to sustainability and reliability.

Navigating Challenges in MH and DL for Energy Solutions

Both MH and DL offered promising avenues for tackling energy challenges, yet they encountered distinct obstacles. MH struggled with scalability, convergence, computational efficiency, parameter tuning, and real-time operation. DL faced issues of data quality, interpretability, training data size, generalization, and model complexity. Overcoming these hurdles required innovative approaches such as parallelization, hybridization, robust data preprocessing, and model optimization.

Despite these challenges, researchers and practitioners were actively exploring ways to harness the transformative potential of MH and DL in revolutionizing energy systems. In a comparative analysis spanning 2018 to 2023, the document counts underscored the growing interest and research focus on MH, DL, and their intersection in energy applications.

Unlocking Energy Solutions

MH offered a potent approach within DL for energy applications, optimizing neural networks and training methodologies. In a structured framework, MH guided data acquisition, preprocessing, enhancement, DL training, prediction, and validation. The process involved six interconnected steps, ensuring robustness and efficiency in energy management tasks. Parameter sensitivity analyses refined algorithm performance, balancing computational efficiency with solution quality.

However, challenges in computational complexity and practical applicability persisted, particularly in scaling to larger datasets and diverse application domains. Despite limitations, this integrated framework held promise for revolutionizing renewable energy management, offering data-driven decision-making and optimized resource utilization in energy-constrained environments.

Conclusion

In conclusion, the integration of MH and DL offered a transformative approach to energy management. From optimization to grid stability, this synergy drove efficiency, resilience, and sustainability. Challenges persisted, but innovative frameworks promised solutions. Through collaborative research and implementation, researchers can unlock the full potential of renewable energy sources, ensuring a greener planet for generations to come.
