Abstract: A method for managing an energy generation system is disclosed. The system includes a cluster of power generators connected by a connectivity network. Each power generator includes an inverter having a respective controller, and at least a data set available to the controller for controlling the respective power generator. Each inverter transmits through said connectivity network, to the other inverters of the cluster, information concerning said data set available to it, said information being sufficient to check whether the data sets available to each inverter are aligned. Each inverter receives, through said connectivity network, information concerning the data set available to other inverters of the cluster and checks whether the data set available to it is aligned with the data sets available to the other inverters of the cluster.

Abstract: The method is aimed at providing secure multicast communication between a plurality of devices forming a cluster of devices connected to one another by a local network. The method provides for electing a key distribution device and generating a group encryption key in said key distribution device. A secure communication channel is then established between the key distribution device and each device of a group of devices to be connected to the cluster. The group encryption key is transmitted from the key distribution device to the devices to be connected to the cluster and stored thereby. When all devices of the cluster have received the group encryption key, multicast communication among the devices of the cluster can start.

Abstract: A method for regulating power export from an energy generation system to a utility grid is disclosed. The energy generation system includes a plurality of power generators. The method comprises a step of monitoring an actual power exported from the system to the utility grid. The method further includes a step of providing to each power generator a feedback signal, containing information on the power exported by the system to the utility grid. At each power generator a respective regulator provides a regulation signal for the relevant power generator. The regulator can be embedded in the inverter of the respective power generator.

Abstract: The method comprises the following steps: a) establishing a secure communication channel between the first device and the second device; b) transmitting a set of symmetric encryption keys from the first device to the second device under secure transmission conditions through the secure communication channel, and storing the set of symmetric encryption keys in respective protected storage memory areas at the first device and at the second device. When the second device is required to transmit data to the first device, the following steps are performed: c) selecting one of said symmetric encryption keys at the second device; d) generating a data bunch at the second device and encrypting the data bunch with the selected symmetric encryption key; e) transmitting the encrypted data bunch from the second device to the first device; f) decrypting the encrypted data bunch at the first device using the selected symmetric encryption key.
