The Ecovat grid balance system makes it possible to take advantage of the flexibility of energy. This self- steering and self-learning system bases its actions on the weather forecast and actual energy prices in order to react in an optimal way to the imbalanced prices in the grid.
Collective balancing by way of electric-thermal conversion and storage
A grid supported by the Ecovat grid balancing system has the capacity to decide of its own accord which action is the most profitable. The system is operated economically by Ecovat control software. When the energy prices are low or even negative, electrical energy is bought from the grid. When the sun shines, electrical energy is generated by e.g. PVT panels.
De energy generated on one’s own accord or cheaply bought energy is converted into thermal energy at high speed and efficiency and stored in the Ecovat thermal storage tank. Conversion of energy can be done with for instance a heat pump or an electric central heating boiler.
The energy stored can be reused the same night, but it is also possible to keep it stored throughout seasons. When the energy prices or demand is high, the stored energy can be used again or returned to the grid.
Electric- thermal heat exchange
The Ecovat steering software is aimed at the coupling between the barrel and the internal energy network of the coupled built environment and the high-tension network. With this the micro grid is made suitable for grid balance.
By using smart neutral networks this freedom of choice is being economically filled in an optimal way. This fully automated and with the use of existing data and future expectations. The Ecovat steering software makes sure that on the basis of actual weather forecasts and energy prices action is being undertaken in the right place and on the right time.
The steering software consists of three steps:
- Forecasting of energy currents
- Matching (optimizing) of demand and supply on local level
- Steering of equipment so that the target function on the micro grid can be optimally reached (for example by maximizing profits by trading in the imbalanced market).
On our way to a 100% sustainable energy system
The result is a system that carries out an automated and in an optimal way possible grid balance. The Ecovat grid balance system does not only provide an optimized balance in the national electric network, but turns the energy storage also into an earning model for the user.
