Summary

Over the past decade, power systems worldwide have undergone a profound transformation driven by the rapid proliferation of renewable energy sources and the emergence of novel, high-demand loads. Photovoltaic arrays, wind farms, and other distributed generation units have shifted the conventional paradigm of centralized electricity production toward a more decentralized, variable landscape. At the same time, emerging loads, e.g., electric vehicle charging infrastructures, data centers, communication base stations, distributed energy storage systems, and flexible industrial processes, have introduced new patterns of consumption that can vary significantly over short timescales. This confluence of variable generation and dynamic demand is redefining how modern grids must be planned, operated, and controlled. Understanding the interactions between these elements is critical to ensuring reliability, efficiency, and stability as the power sector transitions toward a low-carbon future.


The special issue invites researchers, engineers, and industry professionals to contribute their latest findings, methodologies, and case studies.


Topics of interest include, but are not limited to:
· Protection and control in grids with high inverter-based generation and bidirectional power flow
· Fault ride-through compliance and post-fault recovery strategies for DERs
· Fast and accurate islanding detection techniques for inverter-dominated feeders
· Control and stability analysis of grid-connected renewable energy and emerging loads
· Application of advanced optimization technologies for power system with renewable energy sources
· Integration of renewable energy and Hybrid AC/DC Grids
· Optimal dispatch and co-optimization of PV-Storage-EV charging hubs
· V2G control strategies for ancillary services
· Modeling and control of flexible industrial loads for demand-side participation

    Multi-Timescale Flexible Thermal-Electric Coupling Operation of Coal-Fired Thermal Power Units Integrated with Molten Salt Thermal Storage System

    Haifeng Li, Xiao Li, Yuchen Hao, Tao Jin, Yi Cao, Yan Yang, Zheng Wang, Yuze Zhou, Yao Zou
    Energy Engineering, DOI:10.32604/ee.2025.072787

    Abstract The increasing penetration of renewable energy sources (RES) imposes stringent flexibility requirements on thermal power units (TPUs). Integrating molten salt thermal storage systems (MSTS) and thermal-electric coupling technologies into TPUs has the potential to improve their operational flexibility and regulation capability. However, existing research seldom investigates the combined effects of MSTS retrofitting and thermal-electric output coupling on short-term dispatchability, especially under rapid load variation conditions. This study proposes a comprehensive modeling and multi-timescale optimization framework for MSTS-retrofitted TPUs with rapid load variation capability, enabling coordinated thermal and electrical dispatch in both day-ahead and real-time stages.… More >

    Analysis of DC-Side Harmonic Characteristics and Optimization of Filter Design for Hybrid DC Transmission Systems

    Chunyan Li, Luo Li, Yushuang Li, Yong Jia, Wenyan Li
    Energy Engineering, Vol.122, No.10, pp. 4313-4330, 2025, DOI:10.32604/ee.2025.070187
    (This article belongs to the Special Issue: Operation and Control of Grid-connected New Energy and Emerging Loads)
    Abstract To accelerate the large-scale integration of renewable energy and support the strategic goals of “carbon peaking and carbon neutrality,” High Voltage Direct Current (HVDC) transmission technology has made significant breakthroughs. Among the various approaches, a hybrid DC transmission system that combines a line-commutated converter (LCC) and a voltage source converter (VSC) retains the inherent fault self-clearing capability of the LCC topology while mitigating the risk of commutation failure when connected to a weak grid. In this paper, based on the harmonic generation mechanisms of hybrid DC transmission systems, an improved 3-pulse harmonic source model of… More >
