Data of an autonomous microgrid with just EV load and PV generation

A real-world example of an autonomous solar microgrid in island mode is the microgrid in Ilmenau, Germany (50.68327945573772, 10.93832428838313), installed as part of the Sofie project to charge electric vehicles. The Project Sofie is supported by the Free State of Thuringia and the European Social Fund Plus. This document presents the data structure for the Sofie project. The available data are measured values of the microgrid and operating data of the charging park.  The observation period of the available data of the First Vision is from 01.07.2023 00:00:00 to 31.12.2023 23:59:59. The second vision of the available data is from 10.01.2024 00:00:00 to 26.06.2024 23:59:59. The data is collected for 6 users in the period, whereby each user is assigned a fixed id. The fixed id for each user can be found in the id-tag in the table transaction_start with 14 digit number.  Each wallbox of the 8 wallboxes has a fixed id from wb1 to wb8. The microgrid is powered by a solar system the microgrid includes energy storage with a capacity of 38.4 kWh. The batteries are integrated into the AC microgrid via inverters. The maximal Power is mentioned as 18 kW.
