evsim 1.7.0

• Replaced multi-core processing from parallel::mclapply() by purrr::in_parallel() using mirai package
• Removed mc.cores parameter from all functions since now the parallel processing must be defined by the user
• Function adapt_charging_features() now filters incorrect sessions and prints a warning

evsim 1.6.1

• Bug fix in ConnectionHours calculation
• Bug fix in get_demand() and get_occupancy() functions
• Bug fix in adapt_charging_features() function: need to convert timezone to UTC to avoid NA in summer time shift

evsim 1.6.0

• 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

• 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

• 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

• 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

• 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.

evsim 0.1.0

• First release
