The invention discloses a prediction, regulation and control method for electric network loads. The method comprises the following steps: acquiring the electricity consumption data of all measured electric devices within a preset period; establishing a conditional random field model, using the acquired electricity consumption data as a training sample to obtain a conditional probability distribution function of electricity consumption in an estimation manner; predicting what is the anticipated electricity consumption and whether an electricity using peak may appear or not in the next prediction period according to the conditional probability distribution function of electricity consumption and the current electricity consumption; interfering the electricity usage of a user according to a preset electricity using strategy when the prediction result is that an electricity using peak appears so as to reduce electricity consumption. Through use of the method, the electricity consumption of electric networks can be better predicted, and the power of devices can be regulated in time before the electricity using peak appears so as to relieve electric network loads.
