Secure Power Distribution Against Reactive Power Control Malfunction in DER Units

Penetration of distributed energy resources (DERs) such as wind, solar and battery units are rapidly increasing in distribution power system (DPS). In view grid reliability efficiency, cyber physical secure these highly important since it can directly impact operations. This paper investigates the dynamic behavior during cyber, natural strikes on reactive control DER units. Various fault scenarios including modifications voltage-reactive (Volt-Var) curve pattern slope curve, dead band; changes capacitive or/and inductive delivery to presented. Further, investigated with presence VAR (volt-ampere reactive) compensation (DVC) system. A southern California 140-bus commercial is selected a test faults analyzed both Matlab/Simulink ETAP simulation platforms. The results evidence that values at significantly affects voltage quality/security affect number switching actions regulators (VRs). contrast, DPS connected DVCs improves quality reduces VRs, also maintained faults.
