摘要

System to distribute electrical energy to a group of electrical devices, comprising the group at least one participant electrical device in an intelligent network and at least one electrical device not participating in the intelligent network, having the participant electrical device in the intelligent network flexibility with respect the execution of a task assigned to it and being connected to an electrical network via an intelligent network using an agent intelligent network agent intelligent network being configured to determine the amount of power versus time that has It is supplied to the grid and therefrom to the electrical device participating in the intelligent network of the group, based on information of the electrical device participating in the intelligent network and the intelligent network, and the system further comprising a counter for measuring the amount of electricity realmen you supplied to the grid and therefrom to the group, characterized by a controller comprising software components to determine the difference between the amount of energy determined by the agent intelligent network which is to be supplied to the group and from the over a period of predetermined time and the amount of energy measured by the meter really group supplied and therefrom along the predetermined time period, the controller being provided as a computer or a server connected to the intelligent network and that signals representing the determined amount of energy by the agent intelligent network which is to be supplied to the group and therefrom over a predetermined time period and signals representing the amount of energy measured by the counter actually supplied to group along the predetermined period of time, to determine the difference in tre such amounts, with the detection of power consumption by at least one participating device by determining the difference between the amount of energy determined by the agent intelligent network which is to be supplied to the group and therefrom to along the predetermined period of time and the amount of energy measured by the meter actually supplied to the group and therefrom along the predetermined time period, the components controller comprising software for simulating a participant electrical device in the virtual intelligent network on based on the determined difference and to provide the agent intelligent network information based on the determined difference so that the agent intelligent network is configured to determine the amount of power versus time that must be supplied to the grid electrical and therefrom to both the device and léctrico participant in the intelligent network to the electrical device nonparticipating group, based on information from both the electrical device participating in the intelligent network and the electrical device nonparticipating group, and the intelligent network, and so the difference between the determined amount of energy by the agent intelligent network which is to be supplied to the group and therefrom along the predetermined time period and the amount of energy measured by the meter actually supplied to the group and therefrom to throughout the period of time is reduced, the controller being adapted to simulate the participant device in the virtual intelligent network with a PI or PID controller; consisting controller in a PID controller adapted to implement a calculation algorithm which has three independent parameters; a proportional parameter, one integral and one derivative, designated P, I and D, respectively, depending on P of an error is present, depending I of an accumulation of past mistakes, and where D is a prediction of future errors based on the rate of change current being given calculation algorithm of the PID controller by: where u (t) is the output of the PID controller, the P, I and D parameters respectively represent proportional gain, integral gain and derivative gain, t represents time elapsed from the start represented by 0, and e (t) represents the error which is the difference between the amount of energy determined by the agent intelligent network which is to be supplied to the group and from the same throughout the period predetermined time and the amount of energy measured by the meter and actually supplied to the group and therefrom along the predetermined period of time.
