Coordinated predictive control in active distribution networks with HV/MV reactive power constraint
Résumé
This paper presents a new real time centralized Model Predictive Control algorithm for distribution networks. Compared to existing works regarding MPC volt var control, the proposed algorithm controls not only the MV voltages but also the reactive power exchange at the distribution and transmission systems interface. Control of reactive power exchange is a new requirement of the European Network Code on Demand and Connection. The controller adjusts the reactive power of the distributed generators and the voltage reference of HV/MV on load tap changers and capacitor banks. This method was simulated on a 20 kV network taking into account actual technical limitations of distribution networks.
