Abstract
A method for managing a distributed battery arrangement, wherein the arrangement comprises a pool of battery assets. The arrangement allows capacity limits to be set for the battery assets. The capacity limits are a first capacity limit (C1) defining minimum charge that is to be maintained in the battery asset; and a second capacity limit (C2) defining maximum charge; wherein capacity falling between the first capacity limit (C1) and the second capacity limit (C2) is a usable capacity range (C3). Usage of the usable capacity range (C3) of the battery assets is controlled for balancing and/or optimization tasks.
Claims12
A method for managing a distributed battery arrangement, wherein
- the arrangement comprises a pool of battery assets;
- the method comprising allowing capacity limits to be set for the battery assets, wherein the capacity limits comprise
- a first capacity limit defining minimum charge that is to be maintained in a battery asset;
- and
- a second capacity limit defining maximum charge that should not be regularly exceeded;
- wherein
- capacity falling between the first capacity limit and the second capacity limit is a usable capacity range, the method further comprising
- centrally controlling usage of the usable capacity range of the battery assets for balancing and/or optimization tasks by
- assigning a first part of the usable capacity range for up regulation of electric grid;
- assigning a second part of the usable capacity range for charging optimization;
- and
- assigning battery capacity above the second capacity limit for down regulation of electric grid.
A method in a local controlling process for managing a battery asset of a distributed battery arrangement, wherein the arrangement comprises a pool of battery assets;
- the method comprising
- allowing capacity limits to be set for the battery asset, wherein the capacity limits comprise
- a first capacity limit defining minimum charge that is to be maintained in the battery asset;
- and
- a second capacity limit defining maximum charge;
- wherein
- capacity falling between the first capacity limit and the second capacity limit is a usable capacity range, the method further comprising
- locally controlling usage of the usable capacity range of the battery asset for balancing and/or optimization tasks of the distributed battery arrangement by
- assigning a first part of the usable capacity range for up regulation of electric grid;
- assigning a second part of the usable capacity range for charging optimization;
- and
- assigning battery capacity above the second capacity limit for down regulation of electric grid.
