v0.10.4

PowerModelsDistribution v0.10.4

• Fix bug in parsing of properties starting with % on pvsystem and storage objects
• Fix bug in parsing of storage kva, kvar, and pf on storage objects

v0.10.3

PowerModelsDistribution v0.10.3

• Fix bug in parsing of storage power loss parameters, which were derived from values specified in percent, not decimal
• Add support for %stored to be used to derive kwhstored if not specified explicitly
• Fix bug in buscoords parser where comments at the end of the line were not stripped

v0.10.2

PowerModelsDistribution v0.10.2

• add exclude kwarg to remove_all_bounds! transformation, to selectively exclude certain asset types
• fix bug in IVR transformer current variables where bounds needed to be iterated over their connections to be applied
• fix bug in objective function for opf_pbs debugging problem, wrong iteration over bus terminals
• fix typo in variable_mc_switch_current_imaginary that overwrote real variables (crsw)
• fix bug in _map_eng2math_switch! where vmin/vmax were taken from f_bus instead of t_bus
• fix bug in _build_eng_multinetwork, where "dss_options" was missing from const _pmd_eng_global_keys
• change enums (SwitchState and Dispatchable) for switches to Reals, was causing problems in loops of OSW problems
• fix bug in variable_mc_bus_voltage_magnitude_sqr and variable_mc_transformer_power_imaginary where _start values were not being iterated over per connection
• depreciate run_ functions in favor of solve_
• add support for relax_integrality (InfrastructureModels ~0.5.4)
• fix bug in variable_mx_real constructor where it was indexing over terminals instead of enumerates
• added storage variables to automatic unit conversion to si units on math2eng transformation
