Method and apparatus for load management of electrical installations

Abstract

The invention relates to a method and a device (1) for load management of electrical installations. According to the invention, the superior server generates a schedule for controlling the electrical components (12-17) combined in the local electrical overall system (10) and connected to the superior network (2) via a common network connection point (11), The superordinate server also transmits the schedule to the local control unit (20) when possible. The control unit (20) controls the controllable components (12‑15) of the local electrical overall system (10) according to the received current schedule or according to a standard schedule if there is no current schedule. At the same time it is monitored that the power transmitted via the network connection point (11) does not exceed a preset power limit value. If there is an excess, the schedule currently used to control the components (12‑15) is modified according to the preset pattern. If the power limit value is not complied with or not fast enough due to this measure, the monitoring device ( 21 ) cuts off the power connection of the individual components ( 12 - 17 ) according to a preset pattern.

Description

technical field [0001] The present invention relates to methods and apparatus for load management of electrical installations. Background technique [0002] Consumers, power generators and / or electricity storage components that are connected to a superordinated network via a common network connection point are usually summarized as a local overall system. Thus, for example, a domestic electrical installation that is connected to the public power supply network via a house connection and can receive power via this network connection point can be regarded as a local electrical system. For example, the electrical overall system can also include photovoltaic installations and thermoelectric installations or storage, such as rechargeable batteries or stationary battery storage for electric vehicles, enabling the power flow of the local overall system to superordinate levels according to local consumption and local generation or discharge of energy storage in the network.

AI Technical Summary

Problems solved by technology

A disadvantage of this prior art is that the electrical system locally requires a high-performance controller capable of processing the measured feed and consumption values ​​with a high sampling rate fast enough to provide a suitable adjustment of the plan in order to comply with the limit values. renew

If the controller is overloaded or there are other interruptions in the planned update, the limit values ​​can be exceeded, which can lead to damage to consumers or generators, or usually at least to subsequent manual reactivation of safety devices at network connection points
