Abstract

High penetration levels of distributed photovoltaic (PV) generation on an electrical distribution circuit may degrade power quality due to voltage sags and swells caused by rapidly varying PV generation during cloud transients coupled with the slow response of existing utility compensation and regulation equipment. Fast-reacting, VAR-capable PV inverters may provide the necessary reactive power injection or consumption to maintain voltage regulation under difficult transient conditions. As side benefit, the control of reactive power injection at each PV inverter provides a new tool for distribution utilities to minimize the thermal losses in circuit. We suggest a local control scheme that dispatches reactive power from each PV inverter based on local instantaneous measurements of the real and reactive components of the consumed power and the real power generated by the PVs. Using one adjustable parameter per circuit, we balance the requirements on power quality and desire to minimize thermal losses. The performance of the proposed control scheme is evaluated via numerical simulations of realistic rural lines in several generation/consumption scenarios. Simultaneous improvement of both the power quality and the magnitude of losses is observed for all the scenarios, even when the renewable generation in excess of the circuit own load.

Claims other papers make about this one

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

  • The linear approximations S_lin_ij(s) and W_lin_ii(s) are close to S_ij and W_ii in practice.

    “The linear approximations S lin ij ( s ) and W lin ii ( s ) are close to S ij and W ii in practice.”

    From Optimal power flow in distribution networks (2018) · cites this paper as [22]

    Section III (p. 3) says that, for a broad class of feeder lines, small quadratic terms and voltage deviations allow the power-flow equations to be approximated by linear LinDistFlow equations. It does not identify the claimed S_lin_ij(s) or W_lin_ii(s) quantities or establish that those particular approximations are close to S_ij and W_ii in practice. (LLM, conf=0.83)

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.
