1. A computer-implemented method for improving power factor, wherein the computer-implemented method comprises:
- collecting consumption data of at least one inductive appliance and at least one capacitive appliance;
building a consumption profile for each of the at least one inductive appliance and the at least one capacitive appliance based on the consumption data collected;
reconstructing reactive power consumption of each of the at least one inductive appliance and the at least one capacitive appliance based on the consumption profile for each of the at least one inductive appliance and the at least one capacitive appliance, wherein said reactive power is distinct from active power, said reactive power being stored in an appliance and said active power being consumed by the appliance; and
computing a single operating schedule encompassing the at least one inductive appliance and the at least one capacitive appliance, in accordance with the reconstructed reactive power consumption, to reduce reactive power flow within the at least one inductive appliance and the at least one capacitive appliance to improve power factor while respecting at least one constraint;
wherein the steps are carried out by instructions that are (i) embodied on at least one non-transitory computer readable storage medium and (ii) executable by at least one computer device.

12. A computer-implemented method comprising:
-
classifying, from a collection of multiple appliances, one or more inductive appliances and one or more capacitive appliances; computing one or more reactive power parameters pertaining to the one or more inductive appliances and the one or more capacitive appliances; and scheduling the one or more inductive appliances and the one or more capacitive appliances together via a single operating schedule to shorten flow of the reactive power within the one or more inductive appliances and the one or more capacitive appliances by minimizing a cost function, wherein said cost function is based on at least (i) a cost for consuming reactive power, (ii) a level of reactive power consumption by the one or more inductive appliances and the one or more capacitive appliances, (iii) a rate for reactive power, and (iv) the number of appliances among the one or more inductive appliances and the one or more capacitive appliances; wherein the steps are carried out by instructions that are (i) embodied on at least one non-transitory computer readable storage medium and (ii) executable by at least one computer device. - View Dependent Claims (13, 14, 15)
