FAQs 6

Can photovoltaic inverters support new energy microgrid systems?

In order to enhance the support capability of photovoltaic inverters for new energy microgrid systems, grid-forming control technology has attracted widespread attention, with Virtual Synchronous Generator (VSG) emerging as a research frontier.

How do grid-forming photovoltaic inverters work?

In grid-forming photovoltaic inverters, when connected to the grid, the PV microgrid system is interconnected with the main grid. When there is a sudden change in active load in the system, the main grid can promptly support the system frequency. Consequently, the system output frequency can recover quickly after a deviation occurs.

Can a frequency droop-based control improve grid frequency response in DPV inverters?

This article proposes a frequency droop-based control in DPV inverters to improve frequency response in power grids with high penetration of renewable energy resources. A predefined power reserve is kept in the DPV inverter, using flexible power point tracking. The proposed algorithm uses this available power reserve to support the grid frequency.

Can a fuzzy algorithm improve grid-forming photovoltaic inverter control?

For tackling challenges such as low inertia and poor frequency stability in high-penetration renewable energy power systems, this paper proposes an adaptive grid-forming photovoltaic inverter control strategy based on fuzzy algorithm.
