DAVIC – Distributed Automation Via Implicit Channel

DAVIC

The main objective of the DAVIC project is to meet the rapidly increasing demand of the electrical energy using existing infrastructure of electrical power generation and distribution in an innovative and more efficient way. The increasing mismatch of energy supply and demand reveals the need for having a robust IT and communication solution in the energy sector to intensify information exchange in the grid. DAVIC is a simulation platform using OmNet++ as underlying tool. Motivation of DAVIC is to provide a fast and reliable simulation platform that can simulate and compare different energy management algorithms like frequency-response algorithms and peak-demand reduction algorithms. It allow not only to simulate conventional power grid issues (energy flows), but also communication processes (information flows) and in future even economic problems (money flows).

At present, large power plants can communicate to each other and coordinate their behaviors according to the market situation while customers have no infrastructure to optimize the utilization of energy. They have always been considered as passive players. The inclusion of communication infrastructure along with the traditional modules in a power system will enable consumers to react on grid parameters and every member will participate actively in the reduction of demand during peak load hours and will increase the security of supply.

OmNet++ (www.omnetpp.org) is an event-based simulation tool that uses C++ as a programming language. As a discrete event simulation tool, the primary application area of OmNet++ is the simulation of communication networks. Due to the requirements of communication infrastructure in power grid, it is proposed to introduce a network simulator into grid simulation. OmNet++ is a very advisable selection on account of its generic and flexible architecture, which makes it easy to be used in power grid simulations. Simulation kernel and utility classes of OmNet++ are utilized to create a testbed, which serves as a platform for experimenting with large electric power systems.

Students may also get involved in this project by working on new applications and control ideas for IT infrastructure in the power system and realize their ideas within the DAVIC simulation environment.

About energyit

Energy & IT is a research group at the Institute of Computer Technology at the Vienna University of Technology. We work in research projects of two domains, on one side power engineering and information technology (IT) on the other side, with our goal of connecting both fields of research. The CO2-complex of problems, rising energy demand, and use of IT are causing a fundamental change of electrical energy usage. The tasks of IT inside the energy system starts with sensory data acquisition of usage data, including databases, electrical energy services, up to global distributed control mechanisms of distributed energy resources.
