Balancing Energy Services
Renewable energies are increasingly contributing to ancillary services. This market until now has been firmly in the hands of conventional generators. But now even small decentralized plants are able to provide balancing energy. Thus, many of the smaller and fluctuating plants can today also reliably deliver primary (FCR), secondary (aFRR) and minute reserve (mFRR) capacity. The core piece is the Virtual Power Plant from emsys VPP that combines decentralized power generation plants such that they can maintain a certain flexibility together. As power from renewable assets can be automatically and precisely throttled, the Virtual Power Plant together with, for example, wind power plants, offers negative tertiary control and thus balances over-production.
As a central marketing and control software, the Virtual Power Plant supports the supplier in the entire value chain of the balancing energy market, starting with the modelling of technical systems, including provision of prequalification documents and a web portal for communication with the plant operators, over the subsequent balancing group management to revenue accounting.
The comprehensive control system also includes the complete communication technology with the transmission system operators and the technical plants, whereas all connections meet or exceed the very high safety requirements.
In view of the trend to economically integrate smaller and smaller decentralized systems into the Virtual Power Plant and thus to enable participation in the reserve markets, all processes are designed for a high number of plants.
Besides biogas, biomass, gas-fired power plants or wind energy plants also lithium-ion batteries and industrial loads are already operatively controlled from the control room. The integration of other technologies, such as solar power, in the balancing energy portfolio is the next step for the progressive 'Energiewende' (energy transition).
