Initial State of Test System Model:
- Batteries are empty (SOC=0)
- All initial temperatures in the building are 21°C
Temporal Resolution:
- The time resolution of some components are 5 seconds, whereas of the others are 10 seconds. Therefore, the fixed time step of the simulation is 10 second. All input data need to be decimated to 10 seconds resolution
- The control signal for the electric heat pump is provided on an hourly base

KIT.TC2.TS1 (Electrical Peak Shaving BESS Sizing) Test System Model Implementation - short description
Short Description
The test aims at shaving electrical peaks in the FlexOffice/SmartFab system. This means that the electrical peak power delivered by the grid should be minimized.
The grid and PV panels (renewable energy source) supply electricity for the system. When excess power is available from PV, and the battery is not full at this time, the surplus electricity is stored in the battery. If there is still remaining power, the redundant electricity is fed into the grid. The renewable energy is supposed to be utilized as much as possible.
Typically, the electrical load includes the production machines in the smart factory, the electric devices and the heat pump in the office. The heat pump acts as power-to-heat component, which uses electricity to heat up the room to keep the temperature in the office comfortable when necessary.
This test should be run repetitively in order to find the optimal battery capacity size that minimizes the object function. The simulation is executed for one week in four different seasons to cover the seasonal variation in temperature and solar irradiation.
