Pricing of multi-energy network flow

The network model bases upon the energy hub concept, which was developed by the Vision of Future Energy Networks” (VoFEN) research group at ETH Zurich in the last years. Keynote of the concept is a combined optimization of different energy carrier. Synergetic effects are expected to give unusual optimization results, when allowing any possible energy conversion inside a specific area that constitute the hub. Costs for the energy consumption or production are generally used as the optimization criteria. Any technologies for conversion and storage are integrated in a coupling matrix, which links input and output. This paper deals with an extension to the optimization part by merging the network flows with the pricing of grid costs. The impact of network flow pricing is at first derived from theory, then translated into the energy hub concept and finally illustrated in an example.
