  • the price estimator device (108) estimates the cost of the requested energy consumption of the energy consumer (300) considering the cost of the energy per unit of the respective energy providers (410, 420).
  • the ranking engine device (104) combines the prediction from the prediction engine (103), the feedback of the candidate energy production providers (410) and energy storage providers (420) and/or candidate grid provider (700), the preferences of users (200), the preference and location of energy consumer (300), as well as the price as estimated from the price estimator (108).
  • the ranking engine device (104) can be used by prediction engine device (103) in order to predict the demand and production of the energy as well as possible congestions of the energy grid (500), the level of possible congestions, current capacity of the energy grid (500), overall capacity of the energy grid (500), and possible malfunctions of the energy grid (500).
  • the ranking engine device (104) ranks pairs of energy consumer (300) and candidate energy providers (410, 420) or triples of energy consumer (300), candidate energy providers (410, 420), and candidate energy grid providers (700). Then the ranking engine device (104) sends the ranking along with the associated pricing to data retrieval device (102) to be pushed to the selected energy provider (410, 420) and in case of triples to the selected energy grid provider (700), considered being the most suitable by the ranking engine device (104).
  • the ranking engine device (104) is further configured to send the ranking information to the candidate energy providers (410, 420) and/or to the candidate energy grid providers (700) which are second most suitable and to receive respective response.
  • the ranking engine device (104) is configured to subsequently send ranking information to the candidate energy providers (410, 420) and/or the candidate energy grid (700) providers in the ranking information until positive response (confirmation) is sent back.
  • the confirmation is send to the consumer (300). If the energy consumer (300) has activated the automatic matching device of the system (100) (not shown) then the confirmation is approved by sending an automatic reply to the consumer request processing device (106). The energy consumer (300) can also manually approve the selection or even request for a new selection by sending a revised request to the system (100). Until the energy consumer (300) approves the request, the assignment transaction is not complete. Only when the assignment transaction is complete the data storage device and the consumer profile database (107) mark the assignment as valid. The chosen and confirmed selection, i.e. the decision of an energy provider (410, 420) as well as a energy grid provider (700) is sent back to the system user (200). A copy of the decision is stored in the data storage device (109) as well as in the consumer profile database (107).
  • the system (100) additionally comprises a routing device (110).
  • the routing device is configured to control routing of the requested energy from the selected energy production provider (410) or the selected energy storage provider (420) to the energy consumer (300) via the energy grid (500). Therefore, the routing device (110) is connected to the energy production provider (410), the energy storage provider (420) and the energy grid provider (700) and is configured to provide requests or commands for routing to them, see dash-dotted arrows in Fig. 3 .
  • the routing device (110) is thus controlling the routing of the energy from the energy production provider (410) or the energy storage provider (420) to the energy consumer (300) via the energy grid (500) of the energy grid provider (700) using dynamic switching, adjusting potentials, adjusting resistances, shifting phases. In other words, the routing device (110) can control routing of the energy through a plurality of energy paths of the energy grid (500) in parallel.
  • the routing device (110) When routing, the routing device (110) considers the data gathered from the at least one energy grid provider (700) by the data retrieval device (102), e.g. under consideration of the current energy grid status, possible congestion of the energy grid (500), the level of possible congestion, current capacity of the energy grid (500), overall capacity of the energy grid (500), or possible malfunctions of the energy grid (500).
