Special Issue Information

Dear Colleagues,

Energy management systems (EMSs) are responsible for delivering an optimal energy scheduling strategy in day-ahead and real-time power markets. An energy management system supports a reliable power grid, maximizes the penetration of renewable energy, and optimizes the cost and economic efficiency associated with the electricity market. To achieve both economic and environmental benefits, EMSs are used to solve dispatch optimization problems for the available production and storage capacity given the market data, real-time state, and operational constraints of the power grid, production, and consumption forecasting information. However, the intermittency and uncertainties caused by the high penetration of renewables and flexible loads pose critical challenge to EMSs.

The aim of this Special Issue is to present the emerging techniques and latest results of EMSs in modern power systems, laying the foundation for future hybrid electrified systems with renewable energies. Presentations and research papers are welcome to be submitted, and the topics of interest for this Special Issue include, but are not limited to, the following:

  • Optimal operation and control strategies for enhancing power system flexibility;
  • Renewable generation and integration techniques in distributed microgrids;
  • Energy storage techniques in electrified power systems;
  • Energy management and economic operation of distributed microgrids;
  • Resilience and security techniques for multi-energy systems;
  • Coordinated operation and communication for transportation electrification systems;
  • Energy routers and power converter topology and design;
  • Advanced controller design for electrified transportation systems;
  • Intelligent algorithms for multi-energy systems;
  • AI techniques and application in EMS;
  • Digital control techniques in power systems;
  • Real-time simulation testing for electrified transportation systems.

We look forward to receiving your contributions.

Accurate load forecasting is crucial to the stable operation of integrated energy systems (IES), which plays a significant role in advancing sustainable development. Addressing the challenge of insufficient prediction accuracy caused by the inherent uncertainty and volatility of load data, this study proposes a multi-energy load forecasting method for IES using an improved VMD-TCN-BiLSTM model. The proposed model consists of optimizing the Variational Mode Decomposition (VMD) parameters through a mathematical model based on minimizing the average permutation entropy (PE). Moreover, load sequences are decomposed into different Intrinsic Mode Functions (IMFs) using VMD, with the optimal number of models determined by the average PE to reduce the non-stationarity of the original sequences. Considering the coupling relationship among electrical, thermal, and cooling loads, the input features of the forecasting model are constructed by combining the IMF set of multi-energy loads with meteorological data and related load information. As a result, a hybrid neural network structure, integrating a Temporal Convolutional Network (TCN) with a Bidirectional Long Short-Term Memory (BiLSTM) network for load prediction is developed. The Sand Cat Swarm Optimization (SCSO) algorithm is employed to obtain the optimal hyper-parameters of the TCN-BiLSTM model. A case analysis is performed using the Arizona State University Tempe campus dataset. The findings demonstrate that the proposed method can outperform six other existing models in terms of Mean Absolute Percentage Error (MAPE) and Coefficient of Determination (R2), verifying its effectiveness and superiority in load forecasting.

In a modern and globalized world, the advances in technology are rapid, especially in terms of energy generation through renewable sources, which is intended to mitigate global warming and reduce all the ravages that are currently occurring around the world. Photovoltaic and biomass generation sources are attractive for implementation due to the abundant energy resources they offer; however, the intermittency of these sources is a disadvantage when it comes to the needs of the load, decreasing the reliability of the system. Therefore, it is essential to use a backup and storage system such as a diesel generator and a battery bank to continuously supply the load demand. This work presents a case study to meet the energy needs of a community made up of 17 low-income homes on an island in the Gulf of Guayaquil in Ecuador. The optimization and economic evaluation of the hybrid system is achieved using specialized software, resulting in the optimized architecture of the renewable energy system based on the available resources of the locality. The architecture is made up of a 22 kW photovoltaic generator and a 1.5 kW biomass generator, while the diesel generator is 12 kW, the battery bank is made up of 58 units of 111 Ah, and the dispatch strategy is load tracking. The results of the economic evaluation indicate that the total cost of the system (TNPC) is USD 96,033, the initial cost for the implementation of the system is USD 36,944, and the levelized cost of energy is USD 0.276, which makes it attractive for implementation. The importance of this research lies in its practical approach to solving electrification challenges in isolated and low-income communities through a hybrid renewable energy system. By demonstrating how intermittent sources like solar and biomass can be effectively combined with backup and storage systems, the study provides a reliable, economically viable, and implementable solution, addressing both the global need to mitigate climate change and the local need for accessible energy in vulnerable regions.

Hybrid energy supply systems are widely utilized in modern manufacturing processes, where accurately predicting energy consumption is essential not only for managing productivity but also for driving sustainable development. Effective energy management is a cornerstone of sustainable manufacturing, reducing waste and enhancing efficiency. However, conventional studies often focus solely on predicting single types of energy consumption and overlook the integration of physical laws and information, which are essential for a comprehensive understanding of energy dynamics. In this context, this paper introduces a multi-task physics-informed multi-gate mixture-of-experts (pi-MMoE) model that not only considers multiple forms of energy consumption but also incorporates physical principles through the integration of physical information and multi-task modeling. Specifically, a detailed analysis of manufacturing processes and energy patterns is first conducted to study various energy types and extract relevant physical laws. Next, using industry insights and thermodynamic principles, key equations for energy balance and conversion are derived to create a physics-based loss function for model training. Finally, the pi-MMoE model framework is constructed, featuring multi-expert networks and gating mechanisms to balance cross-task knowledge sharing and expert learning. In a case study of a textile factory, the pi-MMoE model reduced electricity and steam prediction errors by 14.28% and 27.27%, respectively, outperforming traditional deep learning methods. This demonstrates that the model can improve prediction performance, providing a novel approach to intelligent energy management and promoting sustainable development in manufacturing. Full article

The present study aims to describe the potential sources of energy in Peru with the purpose of implementing them to achieve a sustainable system, taking advantage of the natural resources in the Peruvian land. To achieve this, three alternative scenarios have been defined and analyzed using the LEAP (Long-range Energy Alternatives Planning) software [Software Version: 2020.1.112]. The scenarios are as follows: the first one, the Business-as-Usual scenario, is based on normal trends according to historical data and referencing projections made by Peruvian state entities; the second one is focused on Energy Efficiency, the highlighted characteristic is taking into consideration the efficient conditions in transmission and distribution of electric energy; and the third one, centered on Geothermal Energy, focused on the development of this type of energy source and prioritizing it. The primary purpose of this analysis is to identify the advantages and disadvantages inherent in each scenario in order to obtain the best out of each one. In this way, the intention is to propose solutions based on Peru’s national reality or possible uses of the country’s energy potential to supply its energy demand. Currently, Peru’s energy demand relies on fossil fuels, hydraulic, and thermal energy. However, there is the possibility of transforming this system into a sustainable one by strengthening existing and growing energy sources such as solar and wind energy and new technologies for hydraulic and thermal energy, in addition to considering geothermal energy as the main energy source in the third scenario. The new system mentioned satisfactorily indicates that the CO2 equivalent emissions decrease significantly in the third scenario, with a 15.8% reduction compared to the first scenario and a 9.7% reduction in comparison to the second. On the other hand, the second scenario shows a 5.6% decrease in CO2 emissions compared to the first, resulting from improvements in technology and energy efficiency without requiring significant modifications or considerable investments, as in the third scenario.
