- W4313193575 abstract "The power distribution grid is beginning to host more actors both from generation (i.e., photovoltaics and wind energy systems) and consumption sides (i.e., electric vehicles). For the effective operation of these new actors, new controller structures emerge in the literature. Most of these controllers define their rules and actions as a function of the grid voltage. The main challenge is that the legacy voltage control units of the distribution network such as On-Load tap changers (OLTC), voltage regulators (VR) and cap-banks directly impact the system voltage, hence, the controller operation. This study investigates the effect of OLTC action on the controller operation and pro-poses a local tap-change detection algorithm based on the voltage statistics occurring during and after tap changes. Our research findings first show that load fluctuations severely impact detection accuracy, therefore, cause false detections and rejections. Second, increasing the sampling resolution of voltage measurements could help eliminate some slower fluctuations and improve accuracy. Finally, information exchange among neighboring nodes could jointly detect the tap changes via a voting mechanism with much higher accuracy. We demonstrate the performance of our algorithm on a 13-bus distribution grid model with 208 end-nodes. We used real household power consumption profiles that were collected at L-sec resolution." @default.
