Abstract

A sustainable and climate-friendly energy supply needs flexible and efficient distribution systems. Key factors to implement this kind of systems are intelligent coordination (smart grid approaches) and the integration of different energy sectors. This article introduces the unified energy agent as an agent-based approach for a comprehensive modelling and control of energy conversion systems. This approach enables both the simulation and optimization of coupled energy networks, and then in a next step, the development of corresponding smart grid solutions to be applied in the field. Its applicability for the simulation of coupled networks is presented by a real-world use-case of an innovative combined heat and electrical network, which was implemented for the city of Lemgo, Germany. Preliminary results from the project are discussed and an outlook on future work is given.

Highlights

  • The current transition towards a more sustainable energy supply requires significant changes in the way energy distribution is planned and controlled

  • Public attention is primarily focused on the electricity sector, where the changes are the most obvious due to the increasing use of weather-dependent and volatile renewable energy sources, but other energy sectors are affected by the transition

  • Since the energy agent approach aims for the simulation of networks as well as the development of smart grid control approaches, related works from both areas are included

Summary

Introduction

The current transition towards a more sustainable energy supply requires significant changes in the way energy distribution is planned and controlled. Based on the results of Agent.HyGrid, in the current project InSekt a combined simulation of medium-voltage and district heating networks is currently under development.
