Abstract

A novel power allocation method, as early as in the procurement of electricity, takes account of network congestion and simultaneously enables logical and physical separation of network control and power allocation. An allocation component and a network monitoring component separately from one another detect tasks relating to the allocation of power and via predetermined interfaces exchange information or intermediate states relating to the allocation before the allocation is actually implemented for power control. This enables adaptive power control of power sources and consumer units and the flexible implementation of a plurality of requirements of a modern power distribution network.

First claim

The invention claimed is:

1. A power control method, comprising:
determining an allocation of electrical power by an allocation component on a basis of offers; providing the allocation to a network monitoring component;
checking a feasibility of the allocation by the network monitoring component, wherein the step of checking the feasibility of the allocation by the network monitoring component includes carrying out a validation of line capacities by the network monitoring component, and the validation of line capacities comprises validating based on a power flow calculation;
providing to the allocation component an examined allocation checked by the network monitoring component on a basis of the feasibility of the allocation; and
instigating a power control based on the examined allocation.

2. The method according to claim 1 , wherein the offers comprise at least one offer selected from the group consisting of at least one purchase offer and at least one sale offer.

3. The method according to claim 1 , wherein the determining step comprises allocating the electrical power by the allocation component on the basis of the offers and on the basis of at least one of the following factors which are determined by the network monitoring component: a power flow calculation, available capacities, and power transfer distribution factors.

4. The method according to claim 1 , which comprises instigating the power control on the basis of the examined allocation by checking a condition with the allocation component to determine whether the examined allocation of the network monitoring component corresponds to the allocation of the allocation component and/or a capacity of the network is not jeopardized, and:
if the condition applies, accepting the examined allocation by the allocation component; or
if the condition does not apply, adjusting the allocation.

5. The method according to claim 1 , which comprises providing at least one offer by at least one agent.

6. The method according to claim 5 , wherein an allocation requirement for at least one locally connected device is determined by the agent.

7. The method according to claim 6 , wherein the agent carries out the power control of the at least one locally connected device.

8. The method according to claim 7 , which comprises carrying out the power control on a basis of an allocation notification which is provided by the allocation component.

9. The method according to claim 1 , wherein the examined allocation of the allocation component is provided by the network monitoring component, in which an adjustment of the allocation is carried out in the allocation component on the basis of the examined allocation.

10. The method according to claim 1 , wherein:
the examined allocation of the allocation component is provided by the network monitoring component; and
an adjustment of the allocation is carried out in the network monitoring component on the basis of the examined allocation.

11. A power control device, comprising a processing unit configured to:
determine an allocation of an electrical power based on offers from at least one agent; provide the allocation to a network monitoring component;
receive an examined allocation checked by the network monitoring component carrying out a validation of line capacities, wherein the validation of line capacities comprises validating based on a power flow calculation; and
instigate a power control on the basis of the examined allocation and thereby also based on the line capacities.

12. A power control device, comprising a processing unit configured to:
receive an allocation from an allocation component;
check a feasibility of the allocation by carrying out a validation of line capacities, wherein the validation of line capacities comprises validating based on a power flow calculation and
generate an examined allocation based on the feasibility of the allocation;
provide the examined allocation to the allocation component; and instigate a power control on the basis of the examined allocation.

13. A system for power control, comprising:
an allocation component configured to determine an allocation of electrical power on the basis of offers;
a network monitoring component disposed to receive the allocation of electrical power,
said network monitoring component being configured to check a feasibility of the allocation by carrying out a validation of line capacities by the network monitoring component, wherein the validation of line capacities comprises validating based on a power flow calculation and to provide the checked allocation to the allocation component; and
wherein the power control is instigated on the basis of the checked allocation.
