6 FAQs about [Photovoltaic medium voltage block and photovoltaic panel matching]

Can the MMC be used for grid-connected PV systems?

To the best knowledge, the usage of the MMC for grid-connected PV systems has been proposed either by using the central PV system as a common dc link for the MMC or by integrating PV multi-strings directly to the submodule (SM) of the converter.

What is a MMC based PV system?

The MMC offers both modularity and scalability for large scale grid-connected PV systems by connecting the PV arrays to the SMs of the converter. An energy balancing strategy of the MMC topology-based PV system is proposed.

Can a grid-connected MMC-based PV system provide energy balancing?

This paper addresses the issue and proposes an energy balancing strategy for the grid-connected MMC-based PV system. It uses the internally generated leg currents to control the power flow inside the converter and inject a three-phase balanced current to the grid with low total harmonic distortion.

Are grid-connected PV systems a viable alternative to stand-alone PV systems?

In recent researches, the development of grid-connected PV systems is the main target as it exceeds 99% of the PV-installed capacity compared to stand-alone systems. Grid-connected systems are cost-effective and require less maintenance compared to stand-alone systems [1, 2].

How are grid-connected PV systems classified?

Grid-connected PV systems are traditionally classified by power capacity, which are listed as small-scale, intermediate-scale, and large-scale [ 1 ]. PV generators that are less than 50 kW are usually considered as small scale PV systems.

What is the energy balancing strategy of MMC topology-based PV system?

An energy balancing strategy of the MMC topology-based PV system is proposed. Its principle is based on transferring power between the converter legs and arms to achieve a balanced power transfer to the grid.
