1. A method of proactively adjusting energy demand of at least one outdoor lighting network connected to a smart power grid, comprising:
- collecting first zone energy supply information and first zone load demand information of each of a plurality of first zone lighting units of said lighting network for each of a plurality of first zone subintervals (P1);
collecting second zone energy supply information and second zone load demand information of each of a plurality of second zone lighting units of said lighting network for each of a plurality of second zone subintervals (P1);
receiving electricity prices from a utility for a plurality of future first zone subintervals of said first zone subintervals and for a plurality of future second zone subintervals of said second zone subintervalsproactively adjusting a first zone light operation strategy of said first zone lighting units prior to said future first zone subintervals based on said first zone energy supply information, said first zone load demand information, and said electricity prices (P3); and
proactively adjusting a second zone light operation strategy of said second zone lighting units prior to said future second zone subintervals based on said second zone energy supply information, said second zone load demand information, and said electricity prices (P3).

11. A method of adjusting energy demand of at least one outdoor lighting network connected to a smart power grid, comprising:
-
dimming lighting units of said lighting network according to one of a plurality of lighting unit dimming vectors each corresponding to one of a plurality of demand response levels; wherein said lighting units are dimmed most drastically at a highest of said demand response levels and are dimmed least drastically at a lowest of said demand response levels; receiving a demand response signal corresponding to one of said demand response levels; transmitting a dimming signal to cause dimming of said lighting units in correspondence with said demand response signal; wherein when said demand response signal corresponds to said lowest of said demand response levels a first security level is applied to said dimming signal; wherein when said demand response signal corresponds to said highest of said demand response levels a second security level is applied to said dimming signal; wherein said second security level is more secure than said first security level. - View Dependent Claims (12, 13, 14, 15, 16, 17)
