Distribution Robust Active and Reactive Power Optimization in Distribution Network with PV and Energy Storage System

Along with the high penetration of photovoltaic (PV) and energy storage system (ESS), the operation and control of distribution network face great challenges, such as uncertainty. The traditional stochastic method is insufficient in guaranteeing the network safe operation while the traditional robust optimization method is too conservative to provide economic dispatch decision. Thus, a novel distribution-robust active and reactive power optimization (DR-ARPO) method is proposed in this paper to reduce power losses by regulating the on-load tap changer (OLTC), ESS and PV inverter. The DR-ARPO model is constructed based on Dist-Flow model and solved by the columns and constraints generation (C&CG) algorithm. Case studies are conducted on the IEEE 33 bus system to demonstrate the effectiveness of the proposed method.
