8. The distribution system of electrical loads on distribution network zones of claim 1,
the distribution server configures an electricity utilization load curve for each electricity consumer, and judges whether the electricity utilization load curve exceeds a threshold fluctuation range or not and whether the electricity utilization load curve exceeds a distribution electricity utilization load quota or not;
the distribution server judges whether the current received time stamp information is the next time stamp information of the previously received time stamp information or not according to the received power utilization load information and the received time stamp information sent by the control terminal;
if so, configuring the current electricity utilization load information to an electricity utilization load curve of the corresponding electricity consumer of the control terminal;
an electricity load curve formed with previously received electricity loads;
if not, the electricity utilization load quantity received by the current time stamp is abnormal information, and the electricity utilization load quantity curve is not updated.
9. The distribution system of electrical loads on distribution network zones of claim 1,
the distribution server is also used for acquiring the available electricity utilization load quantity of the current electricity utilization load quantity quota of the electricity consumer;
when the current remaining available power load of the power consumer is zero or reaches a preset value, an alarm prompt is sent to the control terminal;
the used electricity load of the electricity consumer is G (100% -N%) multiplied by m;
n is the percentage of the current power consumer reaching the distributed power utilization load quota, and m is the distributed power utilization load quota of the power consumer in a preset time period;
n% is divided according to the gradient of every 5 to 10%, and the current required power utilization load percentage of the power consumer is set; and when the electricity utilization load G of the electricity consumer reaches a preset value, sending an alarm prompt to the control terminal.
10. The distribution system of electrical loads on distribution network zones of claim 9,
the distribution server is further used for acquiring the state information of the power consumer in a power load using time period, wherein the power load using time period of the power consumer is t ═ K/F + (K/F) × beta, and K selects the minimum value of the available power load and the used power load of the power consumer;
f is the electricity utilization load quantity transmitted to the electricity consumer, and beta is a correction value between 0.35 and 0.4; acquiring a K value, the available electricity load and the used electricity load of an electricity consumer every time a preset time length passes; and when t reaches the preset duration, stopping transmitting the electricity utilization load quantity to the electricity consumer.
