INTEGRATED ENERGY SYSTEM POWER AND EXERGY FLOW ANALYSIS BASED ON MULTI-ENERGY FLOW COUPLING LAW
The paper analyzes the multi-energyflow coupling law of integrated energy system from two perspectives of energy flow and exergy flow,establishes the system flow steady-state tide model and exergy model,studies the calculation method of system tide and exergy flow distribution according to the model characteristics,and verifies the feasibility of the calculation method with calculation examples,and analyzes the calculation data to verify the superiority of the exergy flow mechanism model compared with the traditional black box model.The results show that the tidal current and the distribution characteristics of the radiation flow are analyzed with the data of the calculation example,and it is pointed out that the energy conversion link has the largest exergy loss,which is the weak link of the system,and it is worth to focus on the improvement,while the electric and thermal networks also have some pipe sections with large radiation loss,which should be taken into consideration when optimizing the local network.
