“…Solar and wind energy systems are the most common renewable energy sources readily available and easy to harness [ 10 ]. Other applications include tidal, hydroelectric, geothermal and biomass [ 11 , 12 ]. However, the uncertainty of intermittent solar energy and the variability in wind speed present a challenge for hybrid energy systems [ 13 ].…”

This paper presents a hybrid Smell Agent Symbiosis Organism Search Algorithm (SASOS) for optimal control of autonomous microgrids. In microgrid operation, a single optimization algorithm often lacks the required balance between accuracy and speed to control power system parameters such as frequency and voltage effectively. The hybrid algorithm reduces the imbalance between exploitation and exploration and increases the effectiveness of control optimization in microgrids. To achieve this, various energy resource models were coordinated into a single model for optimal energy generation and distribution to loads. The optimization problem was formulated based on the network power flow and the discrete-time sampling of the constrained control parameters. The development of SASOS comprises components of Symbiotic Organism Search (SOS) and Smell Agent Optimization (SAO) codified in an optimization loop. Twenty-four standard test function benchmarks were used to evaluate the performance of the algorithm developed. The experimental analysis revealed that SASOS obtained 58.82% of the Desired Convergence Goal (DCG) in 17 of the benchmark functions. SASOS was implemented in the Microgrid Central Controller (MCC) and benchmarked alongside standard SOS and SAO optimization control strategies. The MATLAB/Simulink simulation results of the microgrid load disturbance rejection showed the viability of SASOS with an improved reduction in Total Harmonic Distortion (THD) of 19.76%, compared to the SOS, SAO, and MCC methods that have a THD reduction of 15.60%, 12.74%, and 6.04%, respectively, over the THD benchmark. Based on the results obtained, it can be concluded that SASOS demonstrates superior performance compared to other methods. This finding suggests that SASOS is a promising solution for enhancing the control system of autonomous microgrids. It was also shown to apply to other sectors of engineering optimization.

Smart cities and solar energy are crucial components in climate change adaptation and sustainability. The interrelation with United Nations Sustainable Development Goals (SDGs) based on the 7th SDG goal, Affordable and Clean Energy for solar energy, and the 11th SDG goal, Sustainable Cities and Communities for smart cities, catalyze the research in this field. Unfortunately, there are some gaps in integrating smart cities and solar energy, especially in the elevation model and solar potential accuracy factors. It is essential because the highly accurate integrated model is enormously beneficial, especially for stakeholders. Therefore, this study is leveraging the Light Detection and Ranging (LiDAR) technology to provide high-resolution datasets for elevation models and create a precise 3D urban environment model for resilient integrated smart cities climate change. Digital terrain, including Digital Terrain Model and Digital Surface Model, were developed based on precise LiDAR point clouds before two vital surfaces, building rooftops and land parcels, were treated as a fundamental surface for solar potential calculation. The solar potential Return of Investment rate was classified and integrated with the 3D urban environment model. This 3D urban environment model helps visualize and provides a more specific and coherent picture of reality. The potential application of LiDAR data in climate change adaptation and sustainability that can be linked using various technologies and scales is also demonstrated in this study.

The COVID‐19 pandemic made people reevaluate their energy consumption and energy efficiency. It held up a mirror to humanity's opportunistic and ruthless deployment of energy sources. As the city streets went empty and the international air traffic stopped altogether, people witnessed the significant drop in CO2 emissions, realized their dependence upon energy sources, and became aware of global climate change. In addition, with lockdowns and home offices, the demand for energy and the usual peak hours shifted offering a new perspective in energy consumption. The pandemic delivered a devastating blow to the human belief in having the constant and everlasting supply of energy that can be relied upon in everything. All these attracted the attention of researchers focusing on energy consumption and efficiency during the COVID‐19 pandemic. As a result, the vast body of academic literature on the topic burgeoned in the past four years yielding many exciting perspectives and viewpoints. Our paper conducts a comprehensive review of this body of literature employing the bibliometric network analysis of 12960 publications indexed in Web of Science database. It demonstrates the potential benefits and challenges associated with implementing energy‐saving technologies, altering energy consumption behavior, and implementing novel ICT solutions in a post‐COVID world. In addition, it highlights the importance of energy efficiency measures and examines novel technologies that can contribute to a sustainable and resilient energy future. Our findings emphasize the need for robust policies, technological advancements, and public engagement for fostering energy efficiency and mitigating environmental impacts of post‐pandemic energy consumption.
