Abstract

Microgrid is a system of generating and distributing electrical energy. Microgrids include different power systems, each of which has different power capacity, and produces different oscillations. By producing reliable and flexible power, microgrids can ensure the safety and electrical reliability of the network, and reduce energy costs. Microgrid is a small power system with distributed energy sources and loads, which can work in two modes connected to the grid and island. The controller in a microgrid must provide a seamless transition between different modes of operation. By reviewing the studies, the application of microgrids has expanded to respond to the growing energy demand and solve environmental pollution problems. In this paper, a brief overview of the effectiveness of direct current microgrids in the power system has been given. Direct current microgrids do not need frequency synchronization and reactive power management, and in terms of stability, flexibility and complexity, they are superior to alternating current microgrids. The source voltages are variables that control the direct current microgrid power, so they must be well managed to achieve the desired voltage regulation. Various classifications have been stated for microgrid based on control methods, structure, performance and other parameters. This review can be considered as an initial platform for research study in the development of direct current microgrids based on centralized and intelligent control.
