The findings reveal that smart inverters play a crucial role in mitigating voltage violations and improving the hosting capacity of PV systems in distribution networks. Furthermore, optimal inverter settings, strategic placement of PV-BESS, and advanced control algorithms are identified as critical factors for effective DER integration.
The integration of smart inverters in modern power distribution networks has opened new avenues for optimizing the coordination of distributed energy resources (DERs), particularly photovoltaic (PV) systems and battery energy storage systems (BESS).
Ebeed et al. present a novel approach aimed at enhancing the reliability and security indices of distribution networks through the optimal integration of inverter-based photovoltaic (PV) systems, both with and without their inherent DSTATCOM functionality, under conditions of uncertain load demand and fluctuating PV output.
Voltage ride-through capabilities in smart inverters ensure continuous operation during voltage fluctuations or interruptions in the electrical grid. These capabilities enable inverters to withstand short-term voltage variations, such as voltage sags or swells, without disconnecting from the grid.
As DER penetration rises, traditional voltage regulation methods, such as tap changers and on-load tap changers (OLTCs), face limitations in adapting to dynamic DER fluctuations. This has spurred research into advanced control strategies that integrate traditional voltage regulators with the capabilities of smart inverters.
As the integration of PV systems increases, managing voltage levels becomes increasingly challenging due to the propensity for voltage elevations when excess power is injected into the grid.
