Abstract Recent energy router (ER) research has primarily focused on high-voltage DC systems and regional microgrid clusters, enabling energy exchange among large-scale photovoltaics (PV), energy storage systems (ESS), and grid infrastructures; however, compact low-voltage (LV) ERs for in-building DC distribution remain underexplored despite the need for fine-grained power control and integration of localized resources.

SECTION V. Comparison with Conventional Studies In [19], impedance shaping methods are reviewed for disturbance rejection and damping of voltage-source and current-source converters. Based on the classification used in [19], the proposed controller can be categorized as an LC filter voltage-source converter that uses an inner virtual impedance controller.

Abstract : In this paper, we propose a photovoltaic emulator (PVE) composed of a series of connected power diodes with a single constant current source, rather than a power converter-based PVE. Accordingly, this enables readily verifying the operation because a the simple hardware structure and lack of a complex control algorithm. The proposed PVE can be intuitively implemented using the proposed selection criteria for the power diode and equivalent resistances.
