evsim 1.6.1
- Solve bug in
ConnectionHours calculation.
evsim 1.6.0 (2024-10-03)
- Parameter
align_time has been removed from all functions in favour of internal automatic alignment thanks to introduction of funcion is_aligned.
- Changed variable names in
expand_session function (NominalPower -> PowerNominal, RequiredEnergy -> EnergyRequired)
- Bug fix in
adapt_charging_features function: ConnectionHours now rounded to 2 digits to improve accuracy of calculations
- Simulated energy using log-normal distribution with a minimum of 1 kWh and simulated connections with a minimum of 30 minute duration, to be more realistic.
- Bug fix in
get_evmodel_summary()
- New legend formatting for
plot_ts()
- Added parameter
n_sockets to function add_charging_infrastructure() to specify the number of sockets per charging point
evsim 1.5.0 (2024-04-11)
- In
simulate_sessions now user_profiles can also be NULL to use the default evmodel config.
- Changed
get_ev_model to get_custom_ev_model to avoid using auxiliary functions to get GMM from parameters. Thus, the argument parameters_lst has been introduced to directly use all time-cycles parameters, and functions get_connection_models_from_parameters and get_energy_models_from_parameters are now internal and not exported.
- Custom models ratio’s in
parameters_lst argument of function get_custom_ev_model must be now between 0 and 1 and not between 0 and 100, to be consistent with the evmodel created by evprof.
- Introduced
power_interval parameter in get_charging_rates_distribution function. It is used to round the Power values into this interval resolution. It can also be NULL to use all the original Power values.
- Now
plot_ts function plots with the data timezone by default with dygraphs::dyOptions parameter useDataTimezone=TRUE.
evsim 1.4.0 (2024-03-14)
- Renamed
get_n_connections to get_occupancy
- Added function
plot_occupancy_duration_curve
- Removed dependency from
xts package
- Removed parameter
group from plot_ts function
- Improved reference documentation and examples in multiple functions
evsim 1.3.0 (2024-02-04)
- Improved the efficiency of
get_demand and get_n_connections
- Added function
plot_ts to plot time-series in a dygraphs HTML plot
- Added multi-core processing for Windows distribution
- Energy GMM inside of
evmodel also contain the ratio of every charging_rate
- Function
expand_sessions is now exported
- Added functions to create summary tables from
evmodel object
evsim 1.2.0 (2024-01-23)
- Improved functions for calculating demand and occupancy (now with multi-core processing)
- Included more example data (
evsim::california_ev_sessions and evsim::california_ev_sessions_profiles).
- Included functions to create a model from Gaussian Mixture Models parameters.
evsim 1.1.0
- Added
read_ev_model function to read an EV model JSON file generated by package {evprof}
evsim 1.0.0
- Bug fix in the
evmodel class printing function
- Adding California's EV model as example evmodel (
evsim::california_ev_model).
- Function "simulate_sessions" now requires a "user_profiles" parameter with the ratio of every user profile and the optional specific power.
- Add function "get_user_profiles_distribution" to facilitate the creation of the newly requested parameter "user_profiles" by function "simulate_sessions"
- Remove function
update_profiles_ratios in favour of prepare_models. This new function is used inside the simulate_sessions function using the sessions_day and user_profiles parameters to modify the evmodel input.
