Group control method and device for power demand response, cloud platform and storage medium

The invention discloses a group control method and device for power demand response, a cloud platform and a storage medium, and the method comprises the steps: reporting a response amount according to the estimated response amount of all equipment participating in load aggregation before a response period starts; after the response period starts, a control instruction is issued to all the devices participating in load aggregation for response quantity control; in the response period, the following processing is executed periodically: obtaining actual response amounts from all devices at present; and under the condition that it is determined that the actual response amount is smaller than an expected response amount, the equipment with the remaining response amount is selected from all the equipment participating in load aggregation to increase the response amount, the expected response amount is determined according to the reported response amount, and the actual response amount from all the equipment can reach the expectation.
