Effects of pulsed-power loads upon an electric power grid

Abstract

A major purpose of the Technical information Center is to provide the broadest possible dissemination of information contained in DOE's Research and Development Reports to business, industry, the academic community, and federal, state, and local governments. Non-DOE originated information is also disseminated by the Technical Information Center to support ongoing DOE programs.Although large portions of this report are not reproducible, it is being made available only in paper copy form to facilitate the availability of those parts of the document which are legible, Copies may be obtained from the National Technical information Service. Authorized recipients may obtain a copy directly from the Department . of Energy's Technical Information Center.

Combined Seapower: A Combat Power Perspective

“…Whitelegg (2016) concludes that typical AC power system design practices are not robust enough to withstand the rigors of high power pulse load integration. Furthermore, Smolleck, et al, (1991), Baldwin (2004), Dehkordi, et al (2007), Whitelegg (2016), and Boehmer & Temkin (2018) all conclude that pulse load dynamics not only present power quality issues for other electrical consumers, but may also place unexpectedly large stresses on power generation system components with finite life. This is particularly critical in the case of the prime mover generator (Baldwin, 2004) (Dehkordi, Parsapoor, & Hooshmand, 2007), where increased component stress may result in a reduced Mean Time Between Overhaul (MTBO) that results in an increased engine TLC.…”

Hybrid DC Power System for Pulse Load Application: Design, Modeling and Operation

“…The pulse load power profile is described by relatively high peak-to-average power. Such load profiles are also a major concern in telecommunication systems and shipboard applications [5]- [7].…”

Access-Oriented Energy Storage Configuration Method to Stabilize Fluctuation of Pulsed Load

“…Due to the fierce change of reactive power, the rapid fluctuation of voltage near point of common coupling (PCC) will occur, which has seriously negative effect on the operation of electrical equipment such as transformer and voltage transformer (PT) [10], especially in the term of acceleration of insulation aging, occurrence of units oscillation, increase of equipment forced outage and lifespan shortening. Additionally, pulsed load is non-line load whose interaction with grid cannot be described by simple linear superposition [11] [12].…”

“…(10) Furthermore another significant point is to maintain the energy balance during the operating cycle (the sample period) when the charge and discharge energy of the ESS should be approximately zero. Otherwise a revision has to be made to the smoothed to recompense storage losses.…”
