Abstract:

With the recent advancements in power distribution, e.g., higher penetration of distributed energy resources (DERs), there is a significant demand for optimization tools to solve a variety of complex operational and planning problems, such as optimal dispatch, load shedding, and on-load tap changing. We have developed an optimization-focused approach to phase unbalanced power distribution modeling called PowerModelsDistribution, the design and usage of which we will introduce in this talk.

Description:

PowerModelsDistribution (PMD) is an optimization focused toolkit for power distribution networks modeling, designed using JuMP, which allows for a decoupling of the various problems, power flow formulations, and optimization solvers, for easy exploration and application of a variety of power flow problem types and mathematical formulations related to multi-phase quasi-steady-state optimization. PMD includes several nonlinear AC formulations, linear approximations, and relaxations, all based on state-of-the-art peer-reviewed research, and has native support for both single-period and multi-period (time series) problems, the latter of which is especially relevant due to the larger number of energy storage components appearing in power distribution networks. PMD includes a native Julia OpenDSS data format parser, allowing us to validate the results of AC power flow against OpenDSS using a number of IEEE distribution test feeders, and provides a simple avenue to support existing data models for a broad collection of distribution system components such as photovoltaic systems and energy storage.
