Interface for energy regulation: An application for distributed generation control

In this paper the main technical features of IRE (Interface for energy regulation) are presented. It is a control device specified by Enel Distribuzione in order to support voltage regulation and power flow control on MV "active" networks, in the scope of some demonstrative/pilot projects in Italy. IRE performs its functions adjusting active and/or reactive energy of private power plants connected to the MV distribution network. These functions are defined independently from the specific device that actuate the requested variation of power parameters (inverters, storage systems, capacitors, etc). The Distributor can dynamically impose the energy flows conditions for each MV client sending this request to IRE devices along the feeders. IRE will process the request actuating the settings in a reasonable time span. The results of simulations are also described, to demonstrate the effectiveness of the implemented algorithm.
