Modern Solar Power Electronics

What is power electronics?

Power electronics is possibly the most important element in modern smart grid and renewable energy systems. The discussion in the paper will include modern power semiconductor devices and applications of power electronics in energy saving, electric vehicles, renewable energy systems, and grid energy storage.

Why is power electronics important?

The advent of modern power electronics has brought tremendous impact on power systems, besides the usual industrial applications to improve productivity. Power electronics is possibly the most important element in modern smart grid and renewable energy systems.

How does a solar PV system work?

Different structures used in PV system (Walker and Sernia, 2004). The solar PV power can either be delivered directly by injecting the power into the utility grid by solar-to-grid integration or by operating them in islanded mode to supply power to local loads in case of remote locations.

Which microinverter configuration is used for solar PV system?

Figure 11.19. Microinverter configurations for solar PV system: (A) Parallel; (B) Series. The use of a dedicated power converter for each module represents higher implementation costs, the reason why, in most solar PV systems, only one single-phase inverter is used for each solar PV panel (string), as Fig. 11.20 shows.

Why is MPPT important in solar energy system?

MPPT is essential in solar energy system in order to harvest and deliver the maximum power to the load based on the instantaneous atmospheric conditions and requires the array voltage and current as shown in Fig. 2.

Can power electronics be used in grid integration for large-scale Ren generation?

In this article, grid integration using power electronics is presented for large-scale REN generation. Technical issues and requirements are discussed with a special focus on grid-connected wind, solar photovoltaic, and energy storage systems.
