Navajo

|Navajo (Version 4.3) is a minor upgrade of GridLAB-D planned for Fall 2020. Changes and improvements in Navajo will be outlined here.

New Capabilities

 * Ability for global #define statements to take unit values - deltamode_timestep utilizing
 * Addition of global to force complex output format
 * Addition of internal load order for deltamode modules, to make sure things execute in proper order
 * Addition of three-phase or higher-voltage connectivity to the house model
 * Addition of HELICS-interfaceable event field to eventgen object
 * Improvement to house to enable adding the powerflow induction motor to house HVAC models
 * Improvement to evcharger_det to include simple subsecond capabilities and simple SAE J2894 capabilities
 * Addition of powerflow flag to convert models to constant impedance at particular voltage triggers (outside in-rush)
 * Improvements to multi-island powerflow capabilities, including the ability to solve them separately
 * Improvements of wind power capability curve
 * Addition of inverter_dyn object - a new microgrid/dynamics-oriented inverter
 * Addition of DC model to solar object for use with inverter_dyn
 * Addition of sync_check object
 * Addition of ability to export the right-hand-side vector as part of the NR matrix dump

Bug Fixes

 * Performance improvements to NR solver
 * Fix to constant current implementations in load objects to be more intuitive and flexible to off-nominal angles (migration of deltamode capabilities)
 * Fixes to compilation process and files to better handle MSYS2 and cross-platform consistency
 * Fix for _err autotest checking so a failure to fail is not considered a success
 * Fixes for HVAC operation with a tripped breaker
 * Fixes to diesel_dg and existing inverter object for deltamode initialization
 * Fixes to frequency calculation methods to better handle deltamode/QSTS transitions
 * Fix so base line objects can take matrix definitions, though not encouraged
 * Fix for normalized schedules
 * General clean-up of generator and powerflow objects and headers for new API and eliminate erroneous inclusions
 * Tickets (tickets relating specifically to the development of this version)
 * Tickets for 4.3 RC1
