Abstract

Electric Power Systems (EPSs) are of paramount importance in satellites. These systems are responsible for power generation, storage, delivery, and conditioning. A failure in an EPS may hinder all of the aforementioned functionalities, which, consequently, leads to a failure of the whole space mission. There are many technologies available in both industry and the literature of EPSs, where each has its own fault tolerance capabilities. On the other hand, the efficiency of EPSs is an important factor because it promotes having a higher power reserve, thus feeding payloads at all the necessary times. In this article, EPSs for satellite-based microgrids are reviewed, with more of a focus on their energy generation and storage, including their protection schemes. Moreover, sizing guidelines for energy generation and storage systems are also provided.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Batteries in CubeSats are used as the main source of power when the satellite is eclipsed by Earth or to supply peak loads during periods of low solar irradiance.

    “The batteries are used as the main source of power when the satellite is eclipsed by Earth or to supply peak loads during periods of low solar irradiance.”

    From New Horizons for Microgrids: From Rural Electrification to Space Applications (2023) · cites this paper as [84]

    Sections II and IV say CubeSat batteries supply power during eclipse and can also serve peak loads. The claim's low-solar-irradiance condition for peak loads is not supported: Section IV specifically describes their use for peak loads under high solar irradiance. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • CubeSats have the same main components as traditional microgrids (energy generation, storage, loads, and an energy management system), albeit at significantly lower power levels.

    “CubeSats have the same main components as the traditional microgrids, i.e., energy generation, storage and loads as well as an energy management system, albeit at significantly lower power levels.”

    From New Horizons for Microgrids: From Rural Electrification to Space Applications (2023) · cites this paper as [84]

    Section II, “Overall CubeSat Structure” (page unavailable), describes CubeSat PV generation, battery storage, payload loads, and a controller that regulates power harvesting. The copy does not establish that CubeSats have an energy management system comparable to a traditional microgrid’s, or compare their power levels with traditional microgrids. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • CubeSats are mainly powered by multijunction PV cells.

    “Although there have been developments in this respect, CubeSats are mainly powered by multijunction PV cells.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
