Microgrid Converter

What is a power electronic converter in a microgrid?

Figure 1. Power electronic converters in microgrids. In an AC microgrid, power electronic converters are used to convert DC power (from PV cells, batteries, EVs, etc.) or variable frequency AC power (from wind turbines) into 50/60 Hz AC power so that the power can be fed into the AC bus and supply loads.

Can power converter control support the smart microgrid pyramid?

So far, various power converter control methods have been developed. Now it is urgently needed to compare and understand these approaches to support the smart microgrid pyramid. This article provides an overview of the state-of-the-art of parallel power converter control in microgrid applications.

What types of converters are used in microgrids?

Then, different topologies of the converters used in microgrids are discussed, including DC/DC converters, single-phase DC/AC converters, three-phase three-wire, and four-wire DC/AC converters. The remaining parts of this chapter focus on how to optimally design and control these converters with the emerging wide-bandgap semiconductors.

What is the future of dc-dc converters in microgrids?

Abstract: DC Microgrid has a promising future due to its better compatibility with distributed renewable energy resources, higher efficiency and higher system reliability. This paper presents a comprehensive literature review of DC-DC Converters topologies used in DC Microgrids.

How to control power of microgrids based on a PV system?

In Zolfaghari et al. 87 a new control method for power management of microgrids based on a PV system is proposed. In this approach to control the power of each inverter, Fuzzy Logic Controllers (FLCs) have been implemented. In Figure 15, the control methods of converters used in the DC microgrid are categorized.

Why do microgrids need a modular power converter?

The modular design of these converters allows for scalability and redundancy, making them suitable for various microgrid configurations. The integration of renewable energy sources, such as solar and wind, into microgrids has also led to the development of novel converter topologies that can efficiently manage power from these intermittent sources.
