The Austrian SME is active in the field of energy management in industry and residential buildings since decades. In the past years the company developed a novel energy management system (EMS) and expertise in the field of load management.
The ongoing energy transition is characterised by an increasingly decentralised and acyclic generation and storage of electric energy (e.g. photovoltaic, wind energy, biomass, local battery storage,) and energy consuming units with high energy loads (e.g. e-mobility charging stations, industrial processes). As a consequence, energy load peaks are generated in local (e.g. industrial parks) and regional (e.g. municipal energy networks) energy grids. These peaks are essential cost drivers of the power supply for industry and municipal grids. The avoidance of these peaks is one of the major challenges of the ongoing energy transition and the upcoming e-mobility for energy providers and grid owners.
For avoidance of these energy load peaks in energy grids the energy generating units (e.g. photovoltaic module) do have to communicate with energy consuming units (e.g. e-mobility charging station), storage capacities (e.g. batteries) and sensors and information (e.g. weather data) to adjust current and predictable energy consumption with current or predictable energy generation.
This could lead to energy management as for example via the reduction of the charging current of an e- charging station according to the energy supply or via the activation of air-conditioning units in accordance with the expectable photovoltaic energy supply (weather forecast).
II. State of the art
Existing solutions are capable to manage energy loads of single parts of the overall energy grid. For example, they can adjust the loads of an apartment building with a photovoltaic module, an e-charging station, a smart home and a battery. These existing systems are not able to operate a cross-system energy load management with the capability to manage all relevant energy generation units, energy consumption units and storage units in a defined grid (e.g. an industrial park or a city).
1. The developed solution is capable to integrate and manage all (de)centralised energy generating units, energy consuming units, storage units and other information in a regional grid or an industry park.
2. The system is capable to integrate energy generation units, e- charging stations, inverters, energy storage devices, electricity meters and measuring instruments of different manufacturers -> The user is not restricted by the standards of the individual manufacturers.
3. Complex overall optimization algorithm and cascadable electronic building blocks -> scalable from a single-family home to industry and municipalities.
4. A well-practised development team with expertise in the field of measurement and control technology, electrical and network engineering and central building control systems as well as expertise in the world of grid operators and energy suppliers (electricity tariffs).
IV. Application fields
The system enables a scalable business model for smart grid applications:
- from a one-family house to cities (e.g. optimized photovoltaic energy usage)
- from a single company to large scale industry parks
- from a hotel to tourist regions (e.g. skiing region)
- from a single farm to a large agricultural concerns
- from a single store to large shopping chains (solutions across locations)
Within all these application fields the technology can be used to:
- Install, parameterise and administrate a system
- Visualise live data
- Evaluate and analyse data
- Optimize, manage and monitor energy loads in the grid
The solution fulfils all necessary certifications and requirements of grid-owners.
VI. Partner sought
The company is looking for grid operators, energy suppliers and electrical engineers to expand its business (joint venture agreement).
