Abstract-High penetration of photovoltaic (PV) inverters in low voltage (LV) distribution network challenges the voltage stability due to interaction between multiple inverters and grid. As the main objective is to provide more power injection from VSC-based PV inverters, grid stability, reliability and power quality must be maintained or improved by adding cooperative control features to the grid-connected inverters. This paper first gives an overview of bilateral impacts between multiple distributed generations (DG) and grid. Regarding of these impacts, recent advances in static grid voltage support functionalities to increase penetration level are compared considering voltage rise limitation. Steady-state simulation study is realized in PSCAD/EMTDC and the results are discussed in terms of total generation efficiency.

Voltage Sag Ride-through Performance of Virtual Synchronous Generator

The Virtual Synchronous Generator (VSG) is an inverter control structure that supports power system stability by imitating a synchronous machine. Because of the restriction of inverter power and current, the VSG performance under disturbances should be evaluated and enhanced. In this paper, the response of the VSG unit to symmetrical and unsymmetrical voltage sags is assessed. A theoretical analysis that traces the trajectory of the state variable of the system during voltage sags is presented. The analysis confirms the effect of the characteristics of symmetrical and unsymmetrical voltage sags on the severity of their consequences. In addition, it is detected that two types of transients appear that must be mitigated: one is the transients during the voltage sag and the other one is the transients after voltage recovery. To prevent overcurrent during voltage sags, voltage amplitude control and output power control are implemented, and to suppress the transients after voltage recovery, virtual inertia control is implemented. The experimental results from a 10 kVA VSG-controlled inverter confirm the effectiveness of the additional controllers.
