KIT.TC2 FlexOffice/SmartFab Electrical Peak Shaving - description
Short Description
The goal of this test case is to optimize the capacity size of stationary storage batteries for shaving the electrical peak demand from the grid caused by controllable and uncontrollable loads attached. The load considered within the system mainly includes the machines in the SmartFab and the electrical consumers in the FlexOffice system configuration. The peak shaving is constrained by the running production machines and the comfortable level of the office temperature. The room temperature in the office should be kept at a comfortable level at the same time. An electrical heat pump is switched on to keep the room warm when necessary. The battery is charged with the excess energy generated from photovoltaics connected in the system. The peak energy used from the external grid is supposed to be reduced by using the energy storage. However, both the regulatory ability and economics cost of the battery increase with the battery capacity size. The test objective is to find the optimum between the peak shaving capability and the cost of installing and using the battery.
