The Model and Energy Measurement of Energy Hub
This chapter proposes a new method to evaluate integrated energy systems which take full consideration of the utilization effect of renewable energy. Exergy analysis of multiple energy system is introduced from the perspective of quality of energy. A new power flow expression of energy hub contain storage is given in order to overcome the disadvantage of traditional power flow expression. This chapter also presents a novel droop control method of energy hubs which contain thermal and electric droop control method in a multiple energy system. The proposed energy hub droop control method can proportional allocate different energy hubs thermal and electric outputs according to the corresponding energy maximum output power of energy hubs to allow independent operation of the energy hubs and ensure the stability of the multiple energy system. The three-dimensional diagrams of energy hub droop control method is presented to integrally represent the relationship between systems parameters and the inputs of energy hub meanwhile solely represent the relationship between systems parameters and each input of energy hub that using proposed droop control method. Numerical simulations demonstrate the effectiveness of the proposed droop control method based on energy hub.
