Confronting the Threat: Analysis of the Impact of MaDIoT Attacks in Two Power System Models

The increasing penetration of Internet of Things (IoT) devices at the consumer level of power systems also increases the surface of attack for the so-called Manipulation of Demand through IoT (MaDIoT) attacks. This paper provides a comparison of the impact that MaDIoT attacks could have on power systems with different characteristics, such as...

Reducing the need for communication in remote, natural waveform co-simulations of electrical power systems: An adaptive approach

Electrical power systems are becoming more interconnected and technologically diverse to accommodate ever increasing shares of non-dispatchable generation. These changes are imposing new requirements on the simulation of electrical power systems. One of these requirements is that simulations integrate models of different subsystems, developed by...

Distributed Co-Simulation for Collaborative Analysis of Power System Dynamic Behavior

Given the complexity, scale and heterogeneity of modern power systems, many comprehensive simulation tasks are almost impossible to carry out without collaboration from multiple institutions. One way to approach collaborative simulation is through co-simulation. In this approach each institution contributes a model and the simulation is run...

Speeding Up AC Circuit Co-Simulations Through Selective Simulator Decoupling of Predictable States

Co-simulation has become increasingly popular as a tool for dealing with the unprecedented complexity of modern engineering systems, such as electrical power systems and the AC circuits that compose them. Co-simulation is useful when migrating the models of each subsystem to a single monolithic simulator is either impractical or impossible,...

Co-simulation for Cyber Security Analysis: Data Attacks against Energy Management System

It is challenging to assess the vulnerability of a cyber-physical power system to data attacks from an integral perspective. In order to support vulnerability assessment except analytic analysis, suitable platform for security tests needs to be developed. In this paper we analyze the cyber security of energy management system (EMS) against data...
