Abstract
A plurality of edge of network grid volt ampere reactive (VAR) sources are provided in a power system in order to effectuate control at a customer level, which in turn effectuates control at a feeder level, which in turn effectuates control of an entire power system or wide area electric grid network. By optimally selecting voltage setpoints and applying such voltage setpoints to the plurality of edge of network grid VAR sources, the power system can be configured to self-balance, power factor compensation can be determined without the need for measuring load power factor. Moreover, traditionally volatile voltages at the feeder can be flattened, and VAR control can be realized.
Claims20
A computer-implemented method for voltage and volt ampere reactive (VAR) control of a power system, comprising:
- determining a transformer voltage setpoint;
- and
- determining voltage setpoints for a set of distributed VAR devices implemented in the power system to be equal to that of the transformer voltage setpoint to effectuate self-balancing of the power system.
A system, comprising:
- a service transformer;
- a load coupled to the service transformer, and
- at least one distributed VAR device coupled to the load, the at least one distributed VAR device being operative in response to a voltage setpoint, wherein the voltage setpoint is associated with a controllable transformer on a high-voltage or primary side.
