Abstract
This review paper discusses power quality considerations for direct current (DC) electric power distribution systems, particularly DC microgrids. First, four selected sample DC architectures are discussed to provide motivation for the consideration of power quality in DC systems. Second, a brief overview of power quality challenges in conventional alternating current (AC) distribution systems is given to establish the field of power quality. Finally, a survey of literature addressing power quality issues in DC systems is presented, and necessary power quality considerations in DC distribution system design and operation are discussed.
Highlights
Direct current (DC) architectures for electric power distribution systems and microgrids have been increasingly explored with the goals of more efficiently serving most modern loads that require DC power and, need to have alternating current (AC) to DC conversion stages when powered from conventional power distribution grids [1]
In low voltage DC power systems, damaging resonance currents, unacceptable electromagnetic interference (EMI), or problematic voltage oscillations can result from current harmonics on the DC bus, and a detailed harmonic study needs to be a consideration in the design of DC distribution systems [60]
DC architectures for electric power distribution systems and microgrids have been explored in literature with the goals of more efficiently serving modern loads and integrating distributed generation and storage
Summary
Direct current (DC) architectures for electric power distribution systems and microgrids have been increasingly explored with the goals of more efficiently serving most modern loads that require DC power and, need to have alternating current (AC) to DC conversion stages when powered from conventional power distribution grids [1]. As indicated in [17], power quality issues and solutions found in mobile power distribution systems cannot be necessarily directly applied in general to stationary applications that are the focus of this paper because of technical and commercial issues (e.g., different grounding and dissimilar cost requirements). Many of the power quality issues that apply to mobile power distribution systems are still discussed in this paper, the discussion here focuses on stationary systems and applied on a general context instead on considering the particular conditions found in mobile applications. The current literature addressing the power quality issues for DC distribution systems is surveyed.
