Traditionally, dispatch-only electricity market models use an hourly time resolution. If investment decisions become part of the cost function, problems with the computation time may occur. Reducing the time resolution may significantly boost computation time, however, the effects have not been fully investigated. This paper not only targets at understanding and estimating the error caused by reduced time resolution, but it also describes a novel method for the usage of variable time step lengths.
