Integrated Energy Smart Management System Architecture Design Based on Plantwide Control

In order to adapt to the regulation and management requirements of the integrated energy system, this paper carried out the research of integrated energy intelligent management and control system. According to the design concept of plantwide control, the hierarchical structure of multi-energy complementary coordinated control, energy regulation and management was proposed. In the multi-energy complementary coordinated control, a unified coordination controller is designed to comprehensively coordinate various control methods to ensure the safe and stable operation of the regional integrated energy system. The energy regulation and management system is inherited, and the information exchange with the energy trading and decision-making system is carried out. It has the functions of the energy efficiency analysis, energy monitoring, energy scheduling and optimization, "generation-grid-load-storage" collaborative optimization, which could provide optimized settings for the lower layer control, and achieve regional integrated energy stratification and control, and improve the whole energy efficiency of the energy network.
