Method for improving automated scheduling, scheduling server and system for automated scheduling

A system including a scheduling server for improving automated scheduling of charging sessions in a charging system for electric vehicles, and the charging system, wherein the automated scheduling is at least partially based on user settings input by a plurality of users, wherein the scheduling server comprises a user interface, a system interface, at least one processor, and an output interface,

• wherein the user interface is configured to obtain user settings for the plurality of users, the user settings defining user preferences and personal constraints of each user,
• wherein the system interface is configured to obtain system boundary conditions derived from a schedule goal and technical conditions of a technical equipment of the charging system involved to achieve a desired goal that shall be achieved by applying a schedule to be determined,
• wherein the at least one processor is configured to:
• calculate the schedule by solving a scheduling problem specified from a combination of user specific settings and the system boundary conditions;
• predict acceptance probabilities for alternative user settings, which are settings differing from the obtained user settings;
• select at least one alternative user setting and calculating an alternative schedule for each selected alternative user setting;
• evaluate the calculated alternative schedules and an initially calculated schedule with respect to quality measure in order to determine an improvement or deterioration for each alternative schedule;
• determine, based on a result of an evaluation and the predicted acceptance probabilities, an alternative setting to be suggested to a user whose user setting is concerned by the alternative setting;
• and
• read in a user's response to the suggested alternative setting and select another alternative setting in case the user declined, or proceed with accepting the alternative setting as obtained user specific setting and repeating calculation of a schedule, selection of alternative settings, calculation of alternative schedules, evaluation and selecting and suggesting an alternative user setting and read in of the user's response, until a stop criterion is met,
• wherein the output interface is configured to output a last calculated schedule to the plurality of users and to the charging system for controlling charging parameters of the charging system for charging the electric vehicles, wherein the last calculated schedule adapts charging parameters of the charging system, and
• wherein the charging system is configured to control the technical equipment using the output last calculated schedule for directly controlling charging sessions of a plurality of charging stations based on the adapted charging parameters regarding technical limitations including at least one of peak electricity loads and peak energy costs.
