Abstract

Method for using renewable energy sources, comprising

• • at least one remote energy generation plant, which is operated by a renewable energy source,
  • a remote control unit at the location of the at least one remote energy generation plant, which controls the operation thereof, and
  • a central control unit,
    the method comprising the following steps:
• a) Producing a proposed schedule, in which for a future time period presettings for the operation of the at least one remote energy generation plant are established, and transmitting the proposed schedule to the central control unit via a computer network,
• b) Producing a schedule based on the proposed schedule,
• c) Transmitting the schedule from the central control unit to the remote control unit via a computer network,
• d) Automatic control of the at least one remote energy generation plant by the remote control unit according to the schedule.

Claims

1. A method for using renewable energy sources, the method comprising the following steps:

a) Producing a proposed schedule (20), in which for a future time period subdivided into shorter time intervals, presettings for an operation of at least one remote energy generation plant (10) in each of the shorter time intervals are established, and transmitting the proposed schedule (20) to a central control unit (24) via a computer network (22),

b) Producing a schedule (32) based on the proposed schedule (20), wherein the schedule (32) includes presettings for the operation of the at least one remote energy generation plant (10) which is operated by a renewable energy source, in each of the shorter time intervals of the future time period,

c) Transmitting the schedule (32) from the central control unit (24) to a remote control unit (36) at the location of the at least one remote energy generation plant (10), which controls the operation thereof, via a computer network (34),

d) Automatic control of the at least one remote energy generation plant (10) by the remote control unit (36) according to the schedule (32);

wherein when producing the schedule (32) in the central control unit, a comparison of the proposed schedule (20) takes place with a forecast demand and the schedule (32) is produced, adapted to the demand, and optionally deviates from the proposed schedule (20).
