Abstract: Integrated energy system can achieve efficient utilization of energy, and is of great significance in dealing with resource shortage and environmental pollution. Load characteristic analysis and application research are the vital parts and working basis of design, planning and operation of an integrated energy system. Aiming at the key problems about load characteristic analysis and application raised by this paper, a research framework is established. Then, the automatic realization method of bad load data identification and correction is put forward for actual integrated energy system load data. At last, based on the research framework, the load profile and law of the system at different time scales, the feasibility of enhancing the predictability of multiple loads with different types of energy data, and the potential of the integrated demand response between power and cold load are explored. The results show that the proposed framework can fully excavate the load characteristics of integrated energy system, and will play an active role in improving the predictability of load and giving full play to the potential of integrated demand response.
