The research deals with the development of a new dynamic model-based approach for voltage control in MV networks with distributed generation. The overall control system is designed according to a hierarchical structure where a centralized controller computes the references for local Automatic Voltage Regulators associated with the distributed generators (DG). The centralized control action is computed using a Model Predictive Control algorithm based on an impulse response model of the system. In this way, contraints on the voltage profiles and/or on the reactive power flows along the network can be easily included in the problem formulation.
A radial rural network with two feeders is used as case study to analyze the performance of the proposed approach.
