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.

1. Introduction

1.1 Transformation of Electrical Power Systems

The electrical grid has evolved from a centralized, deterministic infrastructure into a dynamic, distributed, and intelligent system. Key drivers include:

  • Renewable energy integration (solar, wind)
  • Electrification of transportation (EVs)
  • Distributed energy resources (DERs)
  • Digital protection and control systems
  • Real-time monitoring and automation

This transformation aligns closely with the principles of Industry 4.0, where cyber-physical systems integrate physical processes with digital intelligence.
