The rapid expansion of extended electric vehicle (xEV) adoption necessitates optimizing energy storage systems (ESS) management for enhanced performance, longevity, and reliability. However, traditional ESS management approaches struggle with real-time state estimation, energy optimization, and predictive maintenance, leading to inefficiencies in battery utilization and sustainability. This paper addresses these challenges by proposing an advanced ESS framework that integrates digital twin (DT) technology with the twin-delayed deep deterministic policy gradient (TD3) algorithm, a state-of-the-art reinforcement learning method derived from the deep deterministic policy gradient (DDPG). This integration enables precise real-time estimation of critical ESS states, including state of charge (SoC), state of health (SoH), state of energy (SoE), and remaining useful life (RUL), thereby enhancing predictive maintenance and operational efficiency. The proposed framework facilitates proactive battery health monitoring, generates early warnings for potential failures, and enables intelligent battery swapping via DT-driven ESS control. By dynamically adapting ESS control strategies, the TD3 algorithm optimizes energy distribution, reduces energy consumption, and improves overall vehicle performance. With a prediction accuracy of 99.8% for SoC, SoH, and SoE, the proposed approach effectively addresses key challenges in xEV ESS management like cell balancing, dynamic charging rate adjustment, battery swapping decisions, and energy optimization, contributing to a more sustainable and efficient EV ecosystem. © 2013 IEEE.

An attempt is made to propose a data-driven approach for detecting islanding in large-scale power systems. The method utilizes data collected by phasor measurement units (PMUs) to develop an equivalent model of the system. In this model, the system is represented by multiple centers of inertia (COIs) linked to a central point known as the center of gravity (COG) through fictitious reactances. These reactances, which are interpreted as the electrical distances between the local COIs and the COG, serve as a valuable indicator for detecting islanding. The occurrence of islanding can be identified by comparing the temporal trends of electrical distance variations across different areas. The effectiveness of the proposed methodologies is evaluated using simulated data from the 73-bus IEEE test system.

The European directives focus on unlocking the potential of final customers in the clean energy transition. With the recent trend of rising electricity and petrol prices, coupled with reduced investment costs in low-carbon technologies, the installation of photovoltaic solar panels for end customers has become more profitable compared to previous years, leading to a shorter payback period. Additionally, to enhance citizen engagement in the integration of renewable energy sources, various forms of local energy-sharing models are discussed in the literature. This paper elaborates on the regulatory framework and policies at the European level concerning renewable energy communities, citizen energy communities, and collective self-consumption, with a particular focus on Croatia’s perspective. It highlights the steps needed to accelerate the realization of energy communities in practice. Under current Croatian regulations, the profit from selling surplus community energy to the supplier cannot be directly remunerated to community members. The results indicate that community members could achieve 20% lower electricity costs annually if the surplus energy were directly remunerated. To avoid losing potential profits from excess energy, the paper models an investment in a community-owned battery storage system, aiming to increase community self-consumption and minimize the amount of energy sold to suppliers. It is shown that with a static sharing scheme, individual community members’ costs can decrease by 11% to 16%, and by up to 20% with a dynamic scheme compared to cases where profit from excess energy cannot be directly remunerated to community members.

Reactive power compensator placement is challenging in distribution systems due to several complex factors and considerations, specifically the complex topology of the distribution network and it involves non-convex optimization problems. Therefore, in this study, the allocation of reactive power compensation devices is proposed by using a flower pollination algorithm (FPA) for decreasing active power losses in a distribution network. The objective of this work is to minimalize the total network power losses by optimally defining the position and capacity of the reactive power compensators, in addition to improving the voltage profile. The proposed approach was applied at the IEEE 33 bus radial distribution network (RDN) for single and multi-units compensation. The results attained are compared with several recent optimization approaches. The results show that FPA is an effectual optimization method for finding solutions for reactive compensator placement issues. © 2023 IEEE.

Decarbonization efforts aimed at tackling the cli-mate change issues rely on increasing use of renewable energy sources (RES) in the power system. In order to maximise their integration, significantly higher rollout of the battery storage systems (BSS) is necessary, even in the EU which set ambitious goal of achieving carbon neutrality by 2050. EU goals will be difficult to realize without incentives to battery storage. In this paper direct subsidies reducing the installation cost of BSS are considered. We use German power market data for the 2017 and 2021: intraday prices, day-ahead prices and primary reserve markets in particular. Battery storage is integrated with photovoltaics (PV) in order to provide electricity to small and medium sized industrial plants. In this setup the multi- objective optimisation (MOO) method to optimise the annual BSS operation is applied and internal rate of return is used to assess profitability. Since the BSS cycle lifetime (determined by market conditions) often exceeds the calendar lifetime, a fall in the profitability occurs which is used to calculate the subsidy level. The results suggest that the obtained subsidy range is within the range reported in practice considering the perfect foresight assumption used in the analysis. Also, lower subsidies are obtained for 2021 due to conditions more favourable for BSS operation. © 2022 IEEE.

Wide adoption of lithium-ion batteries brings up the question of their fast charging ability which is still an issue in many applications. This is probably the most important for electric vehicles, but also for battery energy storage and even consumer electronics. Charging times can be reduced by using new battery materials, but also by using alternative charging strategies. This paper presents a novel method for quantifying battery’s ability to accept charge in some arbitrary time interval. The proposed method can be used to quickly and effectively compare different battery technologies, different charging strategies or any possible charging condition that might be adjusted, while taking into account battery’s charging ability throughout the entire state-of-charge range. This is achieved by introducing novel fast charging comparison metrics. The method is demonstrated by analyzing and comparing the fast charging ability of four lithium-ion battery cells of different chemistries. Input data are obtained experimentally, on a proprietary laboratory testbed.

This paper focuses on the mathematical modeling of electrical grid stability, taking into account the integration of renewable energy sources. Through the "Stability Margins" model, the study examines the effects of adding solar, wind, and hydroelectric energy to the stability of a theoretical electrical grid composed of ten nodes. Using the admittance matrix and Kirchhoff’s power law, a model is developed that analyzes the eigenvalues of the Jacobian matrix to assess the grid’s stability. Stability margins are calculated to estimate how far the grid is from becoming unstable. The results provide a deeper understanding of the impact of renewable energy on electrical grid stability and help identify solutions to maintain grid stability under increasing integration of renewable energy sources. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

Harmonic distortion is one of the monumental power quality disturbances in an electrical distribution system, which originates from power electronic assets such as power electronic devices from consumers and renewable energy integration. Harmonics adversely affect distribution transformers by elevating losses in their components, leading to the reduction of their lifespan. The impact on the transformer losses is a crucial attention especially considering the integration of photovoltaic systems (PV) into distribution network. Therefore, this paper examined the relationship between current harmonics from various photovoltaic penetration towards load losses generated in an oil-immersed distribution transformer in three-phase distribution network with the presence of unbalanced harmonic loads. The simulation was carried out using MATLAB Simulink 2021a software, during which the current distortion was compared evaluated and compared in accordance with a specified standard. As a result, the rise in PV penetration has been demonstrated to lead to increased losses in distribution transformer. © 2024 IEEE.

The accelerated economic development during the latest decades resulted in an increased electricity demand around the world and major challenges for power systems. Moreover, the climate changes mitigation measures triggered significant changes and an increased pressure on all power systems sectors from generation to distribution and consumers. The Optimal Reactive power Dispatch (ORPD) is a key component for reducing the active power losses and improving the bus voltage profiles in distribution networks. In this paper, an Improved Sine-Cosine Algorithm (ImSCA) is proposed for solving the ORPD for a distribution network operating under different load scenarios. The case study presents a performance comparison between the proposed ImSCA and the classical Sine-Cosine Algorithm (SCA) and the reactive power control impact upon the network operational conditions. © 2022 IEEE.

power system security assessment is a major issue among the fundamental functions needed for the proper power systems operation. In order to perform the security evaluation, the contingency analysis is a key component. However, the dynamic evolution of power systems during the past decades led to the necessity of novel techniques to facilitate this task. In this paper, power systems security is defined based on the N-l contingency analysis. An artificial neural network approach is proposed to ensure the fast evaluation of power systems security. In this regard, the IEEE 14 bus transmission system is used to verify the performance of the proposed model, the results showing high efficiency subject to multiple evaluation metrics. © 2022 IEEE.
