Special Issue Information

Dear Colleagues,

According to the European Green Deal and the European Climate Law, the European Commission has proposed to reduce greenhouse gas emissions by 55 percent by 2030 and reach zero emissions by 2050. In addition, human development requires a significant amount of energy, especially in the era of Industry 4.0. Energy demand is increasing in response to the growing number of problems related to environmental degradation and the energy crisis. However, the energy on our planet is finite and limited. Therefore, the production and application of renewable/sustainable energy are particularly important.

Renewable/sustainable energy will be an essential component of energy production and consumption in coming years, as more and more emphasis is placed on carbon neutrality. The share of renewable/sustainable energy in the world's energy supply is increasing, which is good for both the environment and sustainable development. Figuring out how to use evolving technology to intelligent energy systems that reduce energy consumption and protect the environment is critical. In particular, big data and deep learning strategies are especially trusted options for optimizing and monitoring energy consumption. For this reason, this Special Issue focuses on applied science alongside smart systems and sustainable energy to bring together the research achievements of researchers from academia and industry. Topics of interest include, but are not limited to, the following:

  • Optimization and forecasting of renewable/sustainable energy resources;
  • Innovations in smart grids and microgrids;
  • Emerging renewable/sustainable energy techniques;
  • Impacts of the renewable/sustainable energy techniques in environments;
  • Automated guided vehicle techniques in renewable/sustainable power systems;
  • Smart and intelligent grids for renewable and sustainable energy;
  • Energy applicability in power quality, grid stability, and renewable and sustainable flexibility;
  • AI/DL/ML applications in renewable/sustainable energy management systems.

Nowadays, massive photovoltaic power stations are being integrated into grid networks. However, a large number of photovoltaic facilities are located in special areas, which presents difficulties in management. Unmanned Aerial Vehicle (UAV)-assisted data collection will be a prospective solution for photovoltaic systems. In this paper, based on Deep Reinforcement Learning (DRL), we propose a UAV-assisted scheme, which could be used in scenarios without awareness of sensor nodes’ (SNs) precise locations and has better universality. The optimized data collection work was formulated as a Markov Decision Process (MDP), and the approximate optimal policy was found by Deep Q-Learning (DQN). The simulation results show efficiency and convergence and demonstrate the effectiveness of the proposed scheme compared with other benchmarks. Full article

To cope with climate change and other environmental problems, countries and regions around the world have begun to pay attention to the development of renewable energy under the drive of achieving the global carbon emission peak and carbon neutrality goal. The distributed photovoltaic (PV) power grid is an effective solution that can utilize solar energy resources to provide clean a energy supply. However, with the continuous grid connection of distributed energy, it poses great challenges to the power supply stability and security of the grid. Therefore, it is particularly important to promote the local consumption of distributed energy and the construction of the energy internet. This paper aims to study the cooperative operation and energy optimization scheduling problem among distributed PV power grids, and proposes a new scheme to reduce the electricity cost under the constraint of power supply and demand balance. The optimization problem is modeled as a Markov decision process (MDP), and a Twin Delayed Deep Deterministic Policy Gradient (TD3) algorithm is used to solve the MDP problem. Simulation results show that the proposed algorithm outperforms other benchmark algorithms in terms of reducing electricity cost, convergence and stability, and verifies its effectiveness.

In the process of integrating renewable energy sources into DC microgrids, the isolated bidirectional bridge plays a crucial role. Under load disturbances, voltage fluctuations in the microgrid can affect system stability. This study focuses on using a Genetic Algorithm to optimize the parameters of three typical DAB controllers (PI controller based on pole placement, sliding mode controller, and model predictive controller) with the aim of improving voltage stability, especially during sudden load drops. The results demonstrate that controllers optimized using Genetic Algorithm outperform the methods of pole placement and traditional manual tuning significantly. For the PI controller, the maximum drop rate reduced from 8.00% to 4.00%. The phase margin increased from 123° to 126°. In the case of the sliding mode controller, the maximum drop rate decreased from 7.50% to 5.00%. The phase margin increased from 127° to 155°. As for the model predictive controller, the maximum drop rate reduced from 1.00% to 0.70%. The gain margin increased from 25.8 dB to 26.2 dB. These results highlight the potential of using the Genetic Algorithm in optimizing control parameters, offering the prospect of improving the performance and stability of DC–DC converters.

In order to improve the utilization rate of coal generation and reduce carbon emissions from coal-fired boilers, the operation parameters of power plant boilers should be matched with the actual burning coal. Due to the complex and high-risk blending process of multiple coal types, the actual application of coal types inconsistent with expectations may lead to low combustion efficiency of boilers, cause disturbances to the normal operation of thermal power units, increased energy waste and carbon emissions, and even lead to serious explosion accidents. Therefore, the online identification of coal types for thermal power units is of great significance. To obtain the precise type of coal online, in the present work, a data-driven coal identification method is proposed based on convolutional networks that do not necessitate additional hardware detection equipment and are easy to implement. Experimental results indicate that the proposed method exhibits superior performance in comparison to traditional methods, thus ultimately improving the performance of thermal power plant.
