Introduction  Generally， there are various energy forms in industrial park， such as cold， heat， electricity， gas and so on. In most instances， the coupling of various types of energy isn't strong and mutual coordinated conversion isn't realized efficiently， resulting in widespread energy waste and shortage in industrial park. Therefore， it is necessary to carry out the research on comprehensive energy management system of industrial park， so as to accomplish the operation optimization and control of the energy in industrial park.

  Method  This paper described the system architecture， key application of the integrated energy management system based on the characteristics of the energy in industrial park.

  Result  The designed integrated energy management system can provide technology support for coordinated and optimized operation of various energy sources in industrial park.

  Conclusion  Integrated energy management system of industrial park can integrate the controllable resources of various energy forms and improve energy utilization efficiency and achieve the sustainable development of energy in industrial park.
