Abstract

The intermittent energy supply from distributed resources and the coupling of different energy and application sectors play an important role for future energy systems. Novel operational concepts require the use of widespread and reliable Information and Communication Technology (ICT). This paper presents the approach of a research project that focuses on the development of an innovative operational concept for a Smart Integrated Energy System (SIES), which consists of a physical architecture, ICT and energy management strategies. The cellular approach provides the architecture of the physical system in combination with Transactive Control (TC) as the system’s energy management framework. Independent dynamic models for each component, the physical and digital system, operational management and market are suggested and combined in a newly introduced co-simulation platform to create a holistic model of the integrated energy system. To verify the effectiveness of the operational concept, energy system scenarios are derived and evaluation criteria are suggested which can be employed to evaluate the future system operations.

Highlights

In order to reach the climate goals of the Paris Agreement, to which a large part of the world’s community are committed, it is necessary to achieve a high degree of decarbonization across the energy sectors [1]
The influence of the three aspects on the operational concept for the Smart Integrated Energy System (SIES) is crucial, while the prediction of future energy system architectures is difficult at the same time
We present a concept regarding the holistic simulation and operational optimization of an SIES

Summary

Introduction

In order to reach the climate goals of the Paris Agreement, to which a large part of the world’s community are committed, it is necessary to achieve a high degree of decarbonization across the energy sectors [1]. The strategy for achieving these goals is the installation of renewable energy sources, consisting mainly of wind turbines and solar power plants [1] in the electrical energy system. Such intermittent renewable sources are highly dependent on the weather conditions, mainly solar radiation and wind speed. They cannot be operated like conventional fossil power plants, but require high degrees of flexibility while balancing generation and consumption within the energy system [3].
