Research on Multi-time Scale Cooperative Planning Method of Integrated Energy System in Industrial Park Based on Differentiation of Thermal Energy Quality
Establishing integrated energy systems can effectively improve the energy utilization efficiency of industrial parks,but there is a lack of research on the integrated energy system of industrial parks with various thermal qualities.Based on the thermal energy quality,we divided the thermal load of industrial park into steam load and hot water load,and established an integrated energy system of industrial parks with electric,industrial steam and hot water.Aiming for the lowest annualized cost,we established the annual load resource constraints and the typical daily hour scale load bal-ance constraints based on practical data from engineering,and constructed a multi timescale collaborative programming computational model for several alternative devices including tower photothermal.The results of considering thermal en-ergy quality show that distinguishing thermal energy quality can determine the operating modes of different heat-produ-cing devices in the heating and non-heating seasons.The results of planning calculation show that the construction cost of the integrated energy system built is lower,and the amount of planning process is more in line with the expected ob-jectives of the project,which verifies the validity of the calculation model and the feasibility of the planning and design results.
