Cooperative Volt-Ampere Reactive Control for a PV-Enabled Distribution Network with Abnormally High Power Loads
Abstract
This article presents a cooperative volt-ampere reactive (C-VAR) control strategy to regulate voltage while reducing incurred power loss for a photovoltaic (PV) enabled grid experiencing abnormal (unexpected and extremely high) real power loads. The proposed C-VAR method only requires limited communications about power flow and voltage in a subset of nodes locally and is optimization-free. Thus, it is particularly suitable for the real-time voltage control for a distributed large-scale power grid. For demonstration purposes, C-VAR is evaluated using the IEEE 123-node test feeder and compared with benchmark solutions, such as the IEEE Standard 1547 and centralized model predictive control. The results show that C-VAR does not incur too much power loss and quickly drives the voltage back to the desired range under high power loads and PV indeterminacy.

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.
