Model-Based Systems Engineering for Electrical Power Systems in the Era of Industry 4.0
An Integrated Framework for Digital Simulation, SCADA/IoT Systems, Embedded Intelligence, and Digital Twins
Abstract
Electrical power systems are undergoing a profound transformation driven by decarbonization, decentralization, and digitalization. The proliferation of renewable energy sources, inverter-based resources, distributed energy systems, and real-time control infrastructures has introduced unprecedented complexity into power system planning, design, and operation. Traditional engineering approaches—characterized by document-centric workflows and siloed simulation tools—are increasingly inadequate for addressing these challenges.
This research paper proposes a comprehensive Model-Based Systems Engineering (MBSE) framework that integrates system architecture modeling, multi-domain simulation, embedded systems design, and operational technologies such as SCADA and Internet of Things within the broader paradigm of Industry 4.0.
The framework incorporates:
- SysML for system architecture and requirements
- Enterprise Architect for model governance
- MATLAB and Simulink for simulation
- SystemC, Transaction-Level Modeling, and SystemC AMS for embedded and mixed-signal systems
The paper demonstrates how integrating these technologies enables end-to-end traceability, cross-domain simulation, and digital twin deployment, ultimately improving system reliability, reducing lifecycle costs, and enabling intelligent decision-making.
