FAQs 6

How does a virtual synchronous generator control a PV-storage grid-connected system?

A control strategy based on a virtual synchronous generator for a PV-storage grid- connected system is proposed, wherein the energy storage unit performs the MPPT algorithm, and the PV inverter performs the VSG control.

Can grid-forming converters provide a distributed hybrid energy storage control strategy?

To address this issue, this paper proposes a distributed hybrid energy storage control strategy based on grid-forming converters. By flexibly utilizing Virtual Synchronous Generator (VSG) control and virtual impedance control, the power distribution capability of the grid-forming converter is enhanced to meet the needs of hybrid energy storage.

Do photovoltaic grid-connected systems have energy storage units?

Due to the characteristics of intermittent photovoltaic power generation and power fluctuations in distributed photovoltaic power generation, photovoltaic grid-connected systems are usually equipped with energy storage units. Most of the structures combined with energy storage are used as the DC side.

What is a grid-connected control based on a virtual synchronous generator?

In this paper, a novel grid-connected control by synergizing the GFL and GFM methods based on the virtual synchronous generator (VSG) is proposed. Subsequently, the small-signal model for the proposed control is constructed to analyze the stability of the converter with the proposed control.

How do energy storage units control MPPT and VSG?

To realize control of MPPT and VSG, the energy storage unit maintains the difference between the inverter output power and the output power of the photovoltaic module. Therefore, the energy storage unit adopts a power loop and current loop control. The control strategy implements separate control of the VSG and MPPT functions.

How do hybrid energy storage control methods work?

Existing hybrid energy storage control methods typically allocate power between different energy storage types by controlling DC/DC converters on the DC bus. Due to its dependence on the DC bus, this method is typically limited to centralized energy storage and is challenging to apply in enhancing the operation of distributed energy storage.
