The DERs can create data to indicate realtime local demand and local energy capacity of the DERs. Based on DER information and realtime market information, the system can compute how to provide one or more services to the power grid based on an aggregation of DER energy capacity. ## Claims ### Claim 1 A distributed energy resource (DER) node, comprising: a four-quadrant energy meter to gather realtime data for a customer premises, including information about local demand and information about energy generation to indicate inflow and outflow of both real power and reactive power for the customer premises from a power grid; a node controller to determine from the realtime data, a quadrant of apparent power operation for the customer premises, and determine based on grid conditions of the power grid, a desired quadrant of apparent power operation for the customer premises; and a power converter to adjust a ratio of real power to reactive power to change the quadrant of apparent power operation to the desired quadrant of apparent power operation. ### Claim 2 (depends on 1) The DER node of claim 1, wherein the node controller is to determine the desired quadrant of apparent power operation based on dispatch control received from the power grid. ### Claim 3 (depends on 1) The DER node of claim 1, further comprising: a sensor to detect the grid conditions of the power grid; wherein the node controller is to determine the desired quadrant of apparent power operation based on information from the sensor. ### Claim 4 (depends on 1) The DER node of claim 1, wherein the power converter is to adjust the ratio of real power to reactive power, including to provide real power, reactive power, or a combination of real power and reactive power from the energy generation of the DER. ### Claim 5 (depends on 1) The DER node of claim 1, wherein the power converter is to adjust the ratio of real power to reactive power, including to provide reactive power for the local demand from real power from the power grid. ### Claim 6 (depends on 1) The DER node of claim 1, further comprising: a battery to provide local storage, wherein the realtime data for the DER node further includes a storage capacity of the DER. ### Claim 7 (depends on 6) The DER node of claim 6, wherein the power converter is to adjust the ratio of real power to reactive power, including to provide real power, reactive power, or a combination of real power and reactive power from the local storage of the DER. ### Claim 8 (depends on 1) The DER node of claim 1, wherein the node controller is to determine the desired quadrant of apparent power operation based on realtime market demand for the power grid. ### Claim 9 (depends on 1) The DER node of claim 1, wherein the power converter is to adjust the ratio of real power to reactive power to satisfy the local demand without turning off local loads. ### Claim 10 (depends on 1) The DER node of claim 1, wherein the DER node is one of multiple DER nodes that operate as an aggregation of DER nodes, wherein the node controller is to determine the desired quadrant of apparent power operation for the customer premises as part of the aggregation of DER nodes. ### Claim 11 A method in a node of a grid network, comprising: determining, from realtime data gathered with a four-quadrant energy meter for a customer premises, a quadrant of apparent power operation for the customer premises, the realtime data including local demand information and energy generation to indicate inflow and outflow of both real power and reactive power for the customer premises from a power grid; identifying, based on grid conditions of the power grid, a desired quadrant of apparent power operation for the customer premises; and adjusting a ratio of real power to reactive power with a power converter of the customer premises to change the quadrant of apparent power operation to the desired quadrant of apparent power operation. ### Claim 12 (depends on 11) The method of claim 11, wherein determining the desired quadrant of apparent power operation comprises determining based on dispatch control received from the power grid. ### Claim 13 (depends on 11) The method of claim 11, further comprising: detecting the grid conditions of the power grid with a sensor of the customer premises;
