Design and Application of An Integrated Energy Management System for Park Enterprises

An integrated energy management system (IEMS) based on energy internet architecture is proposed for the comprehensive energy management and energy-saving and emission reduction needs of park enterprises. The system has the characteristics of multi-energy data acquisition, diversity of communication channels, and excellent scalability. In order to solve the compatibility of communication between various acquisition terminals and the system, the interface converter communication conversion is added to upload to the concentrator via the RS485 bus to establish a connection with the master station. It can not only realize the acquisition of multi-energy information such as electricity, water, gas, heat/cold, etc. on the IEMS, but also introduces renewable energy and energy storage on the supply side, improves the energy supply reliability of park enterprises and reduces dependence on external energy networks. In order to meet the integrated energy business needs of enterprises in different parks, this paper studies and analyzes the applicable businesses of various algorithms in IEMS multi-energy collaborative optimal scheduling technology, designs the software architecture of the IEMS, and analyzes in detail the functions of each hierarchical unit module of IEMS and the deployment modes of the master stations in different parks. The system has been put into use and various applications have achieved corresponding results.
