Simulation Facts: On this site the algorithm and the mathematical calculation details can be seen. Its about details, how this simulation works and how the data, with which you have to feed your "VPP" (Virtual Power Plant), will be recalculated.   Additionally, explanations of how to include the different fitness-levels of participants and how to deal with different kinds of machines will be found here.   After an anonymous registration on the "KRFTWRK"-website the participant can run a virtual human power plant. Per every "work unit" on a home trainer or in a fitness studio, the participant informs the "VPP" on the "KRFTWRK"-website about the length and intensity of the training units. In the end the total amount of energy gained by the worldwide operating "KRFTWRK"- community can centrally be recorded and evaluated.
