Abstract

The present invention relates to an energy distribution method and system of a multi-energy interconnection system, by establishing an input-output model including various energy input information and output information, and a revenue function corresponding to the above-mentioned input-output model, and then using preset constraints Conditions Calculate the energy distribution space of the multi-energy interconnection system according to the income function, and find the target input parameters and target output parameters that make the unit income of each energy source conform to the Nash equilibrium state from the above energy distribution space, so that the multi-energy interconnection system can be distributed according to the above equilibrium Parameters to determine the target input parameters and target output parameters of the above-mentioned multi-energy interconnection system, and carry out corresponding energy allocation. The obtained allocation scheme can keep the overall income of the multi-energy interconnection system and the unit income of each energy in it at the optimum state, reduce the waste of energy scheduling after allocation, and have a better allocation effect.

Description

Technical field [0001] The present invention relates to the technical field of energy distribution, in particular to an energy distribution method and system of a multi-energy interconnection system. Background technique [0002] With the development of the energy Internet, the energy center coupling of various multi-energy interconnected systems of multi-energy interconnected systems will gradually deepen. For example, the coupling between traditional power systems and natural gas systems is only by gas turbines, that is, one-way conversion of natural gas to electric energy , Transformed into conversion technologies such as electricity-to-gas (P2G) that have emerged in recent years. The above-mentioned electricity-to-gas technology requires the use of surplus electric energy to electrochemically react water and carbon dioxide into artificial natural gas (SNG), which is injected into the natural gas network to achieve electric energy and Two-way flow of natural gas. [0003] The c...
