EVNPECC4 published two research papers at The IEEE International Conference EEE-AM 2025

Following the success of the EEE-AM 2023 conference, Power Engineering Consulting Joint Stock Company 4 (EVNPECC4) continues to make its mark at the IEEE International Conference: Asia Meeting on Environment and Electrical Engineering 2025 (EEE-AM 2025). At the event held in Hanoi from November 5^th to 7^th 2025, EVNPECC4 presented two research papers addressing challenges arising from the integration of renewable energy sources into Vietnam’s power grid.

The IEEE International Conference: Asia Meeting on Environment and Electrical Engineering 2025 (EEE-AM 2025), themed “The Future of Electrical Engineering: Trends and Innovations”, was co-organized by the Electric Power University in collaboration with Prof. Dr. Sc. Tran Quoc Tuan (Professor at INSTN, Paris-Saclay University, France) and several partner organizations, including Vietnam Electricity (EVN); the Institute of Energy, Environment and Technology (ISTEE); the Vietnam Electrical Engineering Association (VEEA); and the Vietnam Atomic Energy Institute (VINATOM), among others.

The conference serves as an international forum for networking, knowledge exchange, and the presentation of scientific research across a wide range of fields, including Power Generation and Energy Storage Systems, Artificial Intelligence (AI) and Digital Transformation, Power Systems and Smart Grids, etc. The event brought together scientists, university lecturers, invited guests from universities, research institutes, governmental agencies, energy sector organizations, as well as international institutions operating in Vietnam.

At the EEE-AM 2025 International Conference, EVNPECC4 proudly presented two research papers: Analyzing and Proposing solutions to mitigate the effect of Sub-synchronous Oscillation to wind power plants using DFIG and Coordinated operation strategy of BESS and Pumped Storage Hydropower Plant for Load curve optimization and Frequency regulation in power systems.

In the presentation of the research paper “Analyzing and Proposing solutions to mitigate the effect of Sub-synchronous Oscillation to wind power plants using DFIG”, the two speakers –  MSc. Vo Dang Doan Nghia and Le Ngo Tri Toan, electrical engineers from the Power System Technology Application and Database Centre of EVNPECC4 – provided the readers and audience with a clear understanding of the potential risks posed by Sub-Synchronous Oscillations (SSO) to transmission grids equipped with Fixed Series Capacitors (FSC), particularly when integrating DFIG-based wind farms. These oscillations originate from the operational characteristics of the FSCs. Based on this analysis, the research team proposed applying a Frequency-based Impedance scanning method to enable early detection of possible SSO phenomena within the assessed frequency range of the power system.

In addition, the study recommends deploying a STATCOM (Static Synchronous Compensator) to effectively damp SSO thanks to its superior flexibility and fast dynamic response during disturbances. Conference participants and experts highly valued EVNPECC4’s proposed solution, noting its strong potential for power systems integrating wind farms across the Central and South Central regions of Vietnam. The approach provides grid operators with early SSO detection, allowing timely and accurate actions to protect and maintain grid stability.

Moving to the second research paper, “Coordinated operation strategy of BESS and Pumped Storage Hydropower Plant for Load curve optimization and Frequency regulation in power systems” MSc. Vo Dang Doan Nghia – an electrical engineer from the Power System Technology Application and Database Centre of EVNPECC4 – presented a novel operational model that integrates two of the most suitable energy storage technologies for Vietnam’s current power system: Battery Energy Storage Systems (BESS) and Pumped-Storage Hydropower Plants (PSHP).

To provide a more intuitive understanding, the EVNPECC4 presenter modeled the power grid of Ninh Thuan Province (the region with the highest concentration of wind and solar power in Vietnam) by using DIgSILENT PowerFactory software. Through numerical results and illustrative charts generated from algorithm simulations, the presenter demonstrated the significant effectiveness of the proposed coordinated strategy compared with approaches that rely on only one of the two storage systems. By coordinating the operation of BESS and PSHP, the solution offers an optimal operational strategy for Vietnam’s power system with a high penetration of renewable energy. It maximizes the utilization of renewable generation, as well as reduces energy curtailment. Thereby meeting various requirements of system operators by balancing economic efficiency and environmental sustainability.

As a co-organizer of the conference, the Electric Power University continued to affirm its capability and reputation in hosting international scientific events, creating a platform that connects research, technology, and business, and contributing to the sustainable development of Vietnam’s energy sector amid digital transformation and global integration.

Prof. Dr. Sc. Tran Quoc Tuan expressed his hope that future EEE-AM conferences will remain a prestigious academic forum that links scientists, lecturers, and enterprises domestically and internationally, emphasizing that technological advancement and environmental protection must always go hand in hand on humanity’s journey toward a green future.

The EEE-AM 2025 Conference concluded with 6 plenary sessions, 27 thematic sessions, and 351 high-quality scientific papers. The presentations delivered at the event reflected strong commitment to research, innovation, and international collaboration, aiming toward energy transition, green technology development, and accelerating digital transformation in the energy and electrical engineering sectors.
