PERformance analysis of PV integrated distribution network with combination of difFErent Control strategies and communication neTwork (PERFECT)

Integration of large scale of distributed photovoltaic (PV) generation resources in the distribu tion network can lead to technical challenges, particularly voltage rises caused by PVs power injection at the time of high solar radiation profile and low load demand. It is imperative im portant to apply control functions according to power rating of PV inverter, when their capacities are in wide range. In other words, these control functions need to performed based on available capacity from unequal size of PV inverters. Advanced controls like volt-var and volt-watt could allow the PV inverters gradually reduce their real power output as a function of measured bus voltage and provide reactive power support to maintain the network voltage within constraints. The study is performed to analyse voltage distribution profiles across the nodes, with imple ment of volt-var control (VVC) and volt-watt control (VWC) on PV inverter. The study is con ducted in real-time environment, wherein, PV systems integrated in IEEE 13 bus distribution network is in real-time simulation (RTDS) with control functions performed via update of VVC and VWC. Furthermore, power hardware-in-loop (PV emulator, power amplifier with heating load) is integrated at one bus in the network. The complete operation of hardware components in real-time environment operates as smart-grid, having communication network.
