Optimal Power Flow of Multiple Energy Carriers with Multiple Kinds of Energy Storage

As the organization mode and technology of worldwide energy production and consumption are undergoing significant changes, the study on Energy Internet has attracted extensive attentions due to its broad application prospects. The power to gas (P2G) technology can not only enhance the capability of accommodating fluctuating renewable energy generation output, but also offers more choices for energy storage and delivery. In this context, the coordinated multienergy storage including electricity, heat and gas is first formulated and incorporated into the modeling framework of the well-established energy hub, and then the optimal dispatch of multiple energy power flows with multi-energy storage coordination presented. Finally, a 4-bus multi-energy system is served for demonstrating the proposed method.
