Optimal operation of smart multi-energy hub systems incorporating energy hub coordination and demand response strategy

Abstract

This paper considers the operation and optimization of a smart multi-energy hub system network using the energy hub concept. The case study system network includes integrated solar photovoltaic, thermal power generation units and natural gas CHP unit systems. A demand response - dynamic economic emission optimisation model is applied in the case study and allows for a comparison of energy hub control strategies, including the evaluation of economic, environmental criteria and power import between energy hubs. Results show a significant reduction of more than 50% in both total generation cost and amount of emission when different energy hub control strategies are employed. The results also show that load shifting capabilities of different energy hub loads cannot be ignored as it reduces the electricity bill of energy hub customers.
