Embedding quasi-static time series within a genetic algorithm for stochastic optimization: the case of reactive power compensation on distribution systems [PDF]
Journal of Computational Design and Engineering, 2020 Abstract This paper presents a methodology for the optimal placement and sizing of reactive power compensation devices in a distribution system (DS) with distributed generation. Quasi-static time series is embedded in an optimization method based on a genetic algorithm to adequately represent the uncertainty introduced by solar ...

Data-Driven Distribution System Load Modeling for Quasi-Static Time-Series Simulation
IEEE Transactions on Smart Grid, 2020 This paper presents a data-driven distribution system load modeling methodology targeting quasi-static time-series (QSTS) simulation. The proposed methodology is appropriate for modeling down to the level of the customer transformer, and it has three main features: 1) both load pattern diversity and intra-second load variability are considered, 2) the ...

Implementation of Temporal Parallelization for Rapid Quasi-Static Time-Series (QSTS) Simulations
2019 IEEE 46th Photovoltaic Specialists Conference (PVSC), 2019 Quasi-static time-series (QSTS) analysis of distribution systems can provide critical information about the potential impacts of high penetrations of distributed and renewable resources, like solar photovoltaic systems. However, running high-resolution yearlong QSTS simulations of large distribution feeders can be prohibitively burdensome due to long ...
