EVNPECC4 promotes R&D activities: A foundation for sustainable development
To achieve sustainable development goals and enhance consultancy quality that meets customer requirements, the Executive Boardof Power Engineering Consulting Joint Stock Company 4 (EVNPECC4) has reorganized and strengthened the structure of its in-house Research & Development (R&D) Center. The Center's mission is to lead in R&D, the application of science and technology, digital transformation, and innovation. It is also responsible for managing digital databases, operational data, and power system planning. These efforts aim to create job opportunities and improve the company’s business performance. EVNPECC4 has outlined the following key orientations:
Firstly, EVNPECC4 focuses on the centralized management and effective utilization of digital data collected from UAV, LiDAR, Georadar field surveys, satellite imagery, and GIS mapping. This data supports information delivery and enhances Building Information Modeling (BIM) applications across projects.
Next, EVNPECC4 emphasizes research into innovative application solutions to enhance competitiveness and secure new project contracts. This includes:
- Research on power grid analysis and mitigation solutions for sub-synchronous resonance in thermal and wind power plants.
- Development of infrastructure solutions for nuclear power projects, as well as implementation strategies for both offshore and onshore wind power projects.
- sStudies on HVDC power grid systems, 500kV Back-to-Back (B2B) substations, submarine cable systems, and Battery Energy Storage Systems (BESS) to support renewable energy integration.
- Research on power supply infrastructure for high-speed railway projects.
- Application of Building Information Modeling (BIM) in design and construction management, including the use of 4D BIM animation and QR code-based material management.
- Creation of digital twins using 3D BIM models for real-time monitoring and management of equipment and material operating parameters.
- Exploration of smart grid technologies, clean energy solutions, and smart industrial park models.
- Application of Unity software to develop VR/AR platforms for technical training using virtual models of power grid and power plant projects.
In particular, EVNPECC4 is accelerating the adoption of Building Information Modeling (BIM) in design and construction activities, alongside the integration of digital technology solutions, to comply with the requirements of Decree No. 175/2024/ND-CP dated December 30th 2024, issued by the Prime Minister. The company is also organizing training programs for its engineering team to support in-depth research into BIM-related technology solutions such as artificial intelligence (AI), C# .NET programming, Revit API, Dynamo, Python with the goal of automating design processes and enhancing production efficiency.
Simultaneously, EVNPECC4 is focused on establishing a dedicated team responsible for calculating and analyzing power system operating conditions. This team regularly updates synchronized calculation data, conducts research, and applies new specialized software to ensure system reliability, high operational efficiency, and strict compliance with customer information security requirements. Additionally, software usage is centrally managed to prevent fragmented investments in individual licenses, thereby minimizing waste and optimizing resource allocation.
With its research achievements, EVNPECC4 has demonstrated its expertise and experience in providing consultancy services within the Power Sector, while actively embracing new technologies to meet the demands of projects that require the application of advanced techniques in the current era.
Typically, EVNPECC4 applies new software tools to efficiently analyze and calculate power system operating conditions. This includes:
- Conducting analysis and verification of sub-synchronous resonance (SSR) phenomena for the Hai Duong, Vung Ang 1, and Thai Binh 2 thermal power plants under contracts with project investors.
- Proposing to investors the replacement or conversion of wind turbine technologies to prevent sub-synchronous control interaction (SSCI) when connecting to the 500kV transmission grid equipped with series compensation capacitors.
- Implementing the project “Research and Development of Regulations and Conditions for N-1 and N-2 Criteria Calculations in the Vietnam Power System.”
- Executing the project “Research on Solutions to Ensure Safe Operation of Circuit Breakers for Shunt Reactors in the Transmission Grid.”
- Performing technical analyses to support and justify the necessity of investment in project implementation.

EVNPECC4 conducts research on infrastructure development for the Ninh Thuan Nuclear Power Plant project, including studies on grid connection plans for Ninh Thuan 1 & 2 Nuclear Power Plants to the National Power System. These plans have been reviewed and evaluated by experts from the International Atomic Energy Agency (IAEA) at EVN.

Another clear example is EVNPECC4‘s focus on researching technical solutions for submarine cables. The company successfully fulfilled contracts for the development of technical design documents and detailed design for Vietnam’s first 110kV submarine cable line, which exceeds 70 kilometers in length.
