Quasi-static time-series (QSTS) simulation provides an accurate method to determine the impact new PV interconnections or control strategies would have on a distribution feeder. However, its computational time currently makes it impractical for use by the industry. A vector quantization approach [1-2] leverages similarities in power flow solutions to avoid re-computing identical power flows. While previous work improved the simulation speed, multiple simulations were required to verify the accuracy of the results. This paper proposes a novel circuit-specific quantization algorithm to optimize their speed and accuracy. This sensitivity-based method determines a reasonable quantization strategy prior to running the quantized QSTS simulation.
