Transmission

Abstract

So far the transmission system has not been modelled, although it is a physical necessity to have a network. The main reason was that the existence of a network does not play an explicit role for the dynamics of the hydropower system. Assuming network capacities to be given, the flow of electricity is continuous and does not influence the nature of the dynamic equations driving an optimal plan over periods. However, network effects may influence the quantitative solutions in a way that is different for a hydropower system than systems with, e.g., thermal generation. It may also be interesting to consider transmission regarding the spatial structure of pricing of electricity based on hydro generation, since hydro can be almost instantaneously switched on and off with modest costs.
