Abstract: A method and power transmitter for efficiently controlling power transmission to one or more power receivers in a wireless multi-power transmission system are provided. The method includes performing, when a predetermined measurement cycle arrives, a load measurement; comparing a current load measurement value with a previous load measurement value; determining whether the current load measurement value is increased over the previous load measurement value by at least as much as a first predetermined threshold; gradually increasing, when the load measurement value is increased over the previous load measurement value by at least as much as the first threshold, a transmission power value until a request for a subscription to a wireless multi-power transmission network from a power reception target within a predetermined time limit; and stopping, when the request for the subscription is not received before the time limit is exceeded, power transmission to the power reception target.
