Computer-implemented method for managing a plurality of assets of a virtual power plant

A computer-implemented method for managing a plurality of assets of a virtual power plant, wherein each asset in the plurality of assets comprises at least one battery unit, the method comprising:

• assigning the plurality of assets into a plurality of groups, wherein the plurality of groups comprises at least a reserve group and at least one active group and each asset in the plurality of assets is assigned to one group in the plurality of groups, where-in the assigning the plurality of assets into the plurality of groups comprises assigning the plurality of assets into the plurality of groups for each time slot in a plurality of power grid market times slots;
• in response to receiving an activation signal for power grid frequency balancing, offering as-sets for the power grid frequency balancing from groups in the plurality of groups other than the reserve group by offering assets for the power grid frequency balancing from the at least one active group;
• and
• in response to detecting a need for state of charge adjustment in the virtual power plant, performing the state of charge adjustment using the reserve group.
