W4IPS: A Web-based Interactive Power System Simulation Environment For Power System Security Analysis

Abstract

Modern power systems are increasingly evolving cyber-physical systems (CPS) that feature close interaction between information and communication technology (ICT), physical and electrical devices, and human factors. The interactivity and security of CPS are the essential building blocks for the reliability, stability and economic operation of power systems. This paper presents a web-based interactive multi-user power system simulation environment and open source toolset (W4IPS) whose main features are a publish/subscribe structure, a real-time data sharing capability, role-based multi-user visualizations, distributed multi-user interactive controls, an easy to use and deploy web interface, and flexible and extensible support for communication protocols. The paper demonstrates the use of W4IPS features as an ideal platform for contingency response training and cyber security analysis, with an emphasis on interactivity and expandability.In particular, we present the use cases and the results of W4IPS in power system operation education and security analysis.

Design and evaluation of a cyber‐physical testbed for improving attack resilience of power systems

“…PWDS also serves as a simulation engine with a generic interface for integration into other applications [53]. In our experiments, PWDS simulates the power system in a real‐time environment in which cyber threats and defence mechanisms are implemented.…”

“…RESLab uses PowerWorld Simulator and Dynamic Studio (PWDS) that provides large-scale power system modelling in the steady-state and transient stability timeframes [51][52][53]. It can emulate large-scale grids (up to 82,000 buses) and a distributed computing feature to perform parallel steady-state contingency, transient stability, and available travel capacity analysis.…”

Design and Evaluation of A Cyber-Physical Resilient Power System Testbed

“…These expensive hardware solutions are essential for experiments on electromagnetic transients or power electronics, DERS, or microgrids. PowerWorld Simulator and Dynamic Studio (PWDS) provide solutions for large-scale power system modeling in the steady state and transient stability time frames [29,30,31]. The testbeds that use hardware devices such as SEL relays, phasor measurement units (PMUs), or RTACs for their experiments face challenges in understanding vendor-specific industrial control system (ICS) protocols.…”
