Co-simulation of Intelligent Power Systems

The complexity of energy systems increases as more renewable generation and energy storage technologies are added to the grid. Diverse energy carriers are becoming interconnected and the grids are getting reliant on communication networks for timely operation. The arising complexity is difficult to model with the existing mathematical models and...

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,...

Enhancing PowerFactory Dynamic Models with Python for Rapid Prototyping

DIgSILENT PowerFactory is among the most widely adopted power system analysis tools in research and industry. It provides a comprehensive library of device models and it allows users to define their own. Models for dynamic simulation can be defined in the DIgSILENT Simulation Language (DSL). When the functionality of DSL is insufficient, new...

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...

Co-simulation and Dynamic Model Exchange with Consideration for Wind Projects

This paper discusses and compares two approaches to address technical challenges in performing collaborative studies of power system dynamics. On one side, we consider the model migration approach which is an essential piece of dynamic model exchange. On the other side, we look at the co-simulation approach which is used to couple simulation...
