Abstract
With massive integration of solar photovoltaics (PVs) in the distribution networks, the voltage regulation problem has become one of the serious concerns for distribution network operators. This article proposes a model predictive-based voltage control that optimally coordinates the reference voltage of distribution static synchronous compensator and on-load tap changer, and PV inverters’ active and reactive power set points to maintain network voltages within the operating limits. The two functionalities of the active distribution management system are demand response (DR) and conservation voltage reduction (CVR), which are further explored in the voltage control methodology to enhance energy efficiency of the distribution networks. The proposed methodology is implemented in a 33-bus distribution network to verify its effectiveness for different cases. Furthermore, simulation results demonstrate the benefits of CVR and DR on the proposed methodology.
