Abstract
The project Integrating the Energy System (IES) Austria recognises interoperability as key enabler for the deployment of smart energy systems. Interoperability is covered in the Strategic Energy Technology Plan (SET-Plan) activity A4-IA0-5 and provides an added value because it enables new business options for most stakeholders. The communication of smart energy components and systems shall be interoperable to enable smooth data exchange, and thereby, the on demand integration of heterogeneous systems, components and services. The approach developed and proposed by IES, adopts the holistic methodology from the consortium Integrating the Healthcare Enterprise (IHE), established by information technology (IT) vendors in the health sector and standardised in the draft technical report ISO DTR 28380-1, to foster interoperable smart energy systems. The paper outlines the adopted IES workflow in detail and reports on lesson learnt when trial Integration Profiles based on IEC 61850 were tested at the first Connectathon Energy instalment, organised in conjunction with the IHE Connectathon Europe 2018. The IES methodology is found perfectly applicable for smart energy systems and successfully enables peer-to-peer interoperability testing among vendors. The public specification of required Integration Profiles, to be tested at subsequent Connectathon Energy events, is encouraged.
Highlights
The energy transition refers to the migration toward solely renewable energy sources (RES)feeding the power grid
VHPready focuses on the interoperable communication between distributed energy resources (DER) and a Virtual Power Plants (VPP) operator and does not consider issues with other assets and entities of the energy system that may be needed to fulfil related Use Cases that reach beyond the boundaries of managing a VPP
Having noticed that modern standards offer a plurality of options to realise certain features, all based on the same technical background but with many options, it appears straightforward to use the features that a standard offers as solution building blocks
Summary
The energy transition refers to the migration toward solely renewable energy sources (RES). The sun enables the growth of plants, propels the weather system and thereby the wind and the water cycle, which in addition to photo-voltaic panels and mirror based systems are utilised to generate green secondary energy by wind turbines, hydroelectric power plants, and bio-gases. These primary sources are fluctuating, they are not available in the same amount at all times [1]. The main goal of IES is to provide a workflow for the energy domain that fosters interoperable energy system components required for the communication in Smart Grids.
