The following list showcases new features and enhancements in the latest version of AURORAxmp.
Enhanced Storage Logic
Version 12.3 introduces new options for advanced logic for storage type units. The enhanced logic offers the improved ability to model the intricacies of renewable and storage integration, electric vehicles, and other technologies. It uses an optimization engine which allows the model to solve a more complex problem with numerous types of constraints. If also offers more detailed input options such as the flexibility to shape to the load and price of any set of zones throughout the system.
Ancillary Services Enhancements
This release includes significant enhancements to the ancillary services co-optimization capability in AURORAxmp.
Long-Term Logic Enhancements
Version 12.3 delivers on many client-requested features for long-term capacity expansion studies.
Improved RPS Modeling
Version 12.3 includes a new optional column called Ignore In Capacity Pricing, entered in the Resources and New Resources tables. The column is used to identify resources that should not be eligible to set capacity prices.
New Constraint Types
This release adds two new Constraint Types of LT Capacity Max and LT Energy Max to the options in the Constraint table that may be applied to resources or resource groups.
LTBuildReport Output Table
The new LTBuildReport output table reports information about new resource optiwere actually built. It reports the minimum and maximum options for new resougroup constraints and is helpful to quickly see which constraints were binding.
Version 12.3 includes an exciting new option to run a full security constrained unit commitment (SCUC). When running a nodal solution with Commitment Optimization, AURORAxmp will also take into account the nodal-level constraints in the mixed-integer program that performs the commitment decisions, including branch, corridor, and contingency constraints. In this case, instead of performing one optimization the model will iterate by successively adding the binding transmission constraints until no more constraints are violated.
Nodal Output Using Angles or Shift Factors
As a reminder, recent changes were made to the way that the nodal reporting works when running with Solution Method = Angles or Shift Factors. There is no longer any zonal reporting when using these two methods, so the following output tables will not be reported: FuelByZone, Hub, Link, MultiLink, Pool, Zone, and ZoneEmissions. In addition, the following tables will automatically be reported with the nodal solution values (instead of zonal results): Fuel, Resource, ResourceEmissions, ResourceGroup,and ResourceGroupEmissions. Note that unmapped resources will not be included in the resource type tables.
EPIS, LLC delivers database updates independently of major model enhancements. This model release does include the option to download updated ready-to-run project files and templates, and databases including new Maintenance Schedule (MST) and Resource Modifier (RMT) tables to accompany updated data.
