The EOM: An Adaptive Energy Option, State and Assessment Model for Open Hybrid Energy Systems

Abstract

Abstract-The current transformation process of how energy is supplied attracts great interest from many different market players. As a consequence, many proprietary solutions for "smart" energy applications are flooding the market. This turns out to be rather a problem than part of the solution for the systematic development of future energy grids. Additionally, the absence of necessary standards blocks further developments that enable the creation of novel, market-driven and hybrid control solutions. To overcome these problems, we suggest a standardized control approach for hybrid energy systems by means of a so called Energy Option Model (EOM). This unifying model and the therewith developed decision support system provides the necessary technical understanding and the economic assessment options for network-connected energy conversion systems. Thus, it can be used for single onsite systems as well as for aggregated systems that are controlled in centralized or decentralized manner. This paper presents and discusses exemplary use cases for our EOM that illustrate the centralized as well as the decentralized use of our approach within hybrid energy systems. Overall, we believe that the EOM represents the key approach for a further systematic development of an open hybrid energy grid.

Integrating Peer-to-Peer Energy Trading and Flexibility Market With Self-Sovereign Identity for Decentralized Energy Dispatch and Congestion Management

“…All this requires that the prosumer-agent can understand which energy systems are under its control, and what flexibility each individual system offers. This knowledge is provided by the Energy Option Model [72], a generalized modeling approach to describe the capabilities and thus the flexibility potential of arbitrary energy conversion systems. Depending on the locally available energy systems and a corresponding configuration, these models are used by socalled Energy-Agents, that provide the software-technical foundation for the implementation of prosumer-agents in the context of PEAK [73].…”

Unified Energy Agents for Combined District Heating and Electrical Network Simulation

“…The energy option model (EOM) was first introduced in [6]. It was designed to model the operational flexibility of arbitrary energy conversion systems.…”

“…Therefore, simulation and planning tools that consider both forms of energy at the same time are required. With the concepts of a unified energy agent and the energy option model (EOM), a generic way of modelling arbitrary energy systems has been developed at the University of Duisburg-Essen [5,6]. Based on the paradigms of agents and multiagent systems, combined with a detailed description of the behavior and operational flexibility of the energy systems represented by these agents, this approach aims to seamlessly cover the whole life cycle of a software-based control solution [7].…”

Testbed Application of Energy Agents

“…Information about energy costs or losses are provided and can be used to optimize the execution schedule for minimal costs or maximal efficiency. Examples for EOM-based evaluations and optimizations are given in [22] and [23].…”
