1. A system for monitoring and managing reactive power in an electrical grid, the system comprising:
a plurality of horticultural light sources operatively connected to the electrical grid;
a reactive power monitoring module operatively connected to the plurality of horticultural light sources, the reactive power monitoring module being configured to:
determine or predict distortive effects produced by the plurality of horticultural light sources in the electrical grid; and
send illumination instructions to the plurality of horticultural light sources in response to the determined or predicted distortive effects, the illumination instructions causing an increase of a power factor of at least one of the plurality of horticultural light sources;
an estimation module operatively connected to the plurality of horticultural light sources, the estimation module being configured to:
receive a first set of inputs, the first set of inputs being representative of a power usage profile and/or a spectral density distribution of each of the horticultural light sources; and
output an estimation of an anticipated power factor; and
a decision module in data communication with the estimation module and operatively connected to the plurality of horticultural light sources, the decision module being configured to:
receive the estimation of the anticipated power factor and a second set of inputs, the second set of inputs being representative of a rule associated with a target power factor; and
produce a control signal, based on a comparison between the anticipated power factor and the target power factor, the control signal being sent towards the plurality of horticultural light sources, causing an adjustment of the anticipated power factor of the plurality of horticultural light sources to meet the target power factor.
