Problems solved by technology
However, in practical applications, the water temperature in the heating pipe network is not in an isothermal state, and the temperature of the inlet and outlet nodes at the connection between the heating network and the energy hub is different, so only the hydraulic hydraulic equation is not enough to simulate the heat network, and it is necessary to add The thermodynamic equation handles temperature changes at the nodes where the Energy Hub is connected separately

Description
technical field [0001] The invention relates to the technical fields of integrated energy systems and energy Internet, and in particular to a method for analyzing power flows of multi-energy coupling systems based on extended energy hubs. Background technique [0002] Energy is an important basis for the sustainable development of our country's economy, and energy supply systems are usually considered as separate subsystems with individual energy outputs, such as electricity, heat, gas or hydrogen. In the current vision of smart grid, energy systems at the regional / city level are becoming increasingly complex and diverse. With the popularization of multi-energy low-carbon technologies, such as combined heat and power (Combined Heat and With the development, the interaction between electricity, heat and natural gas networks becomes closer, and different energy carriers are coupled with each other to meet various types of energy needs. Obviously, the traditional energy networ...
