According to the intelligent operation, control and operation and maintenance needs of large integrated energy stations, an intelligent control architecture is proposed, and the form of the control system is analyzed. Based on the completed control logic design of the main equipment, an optimized scheduling model for the system based on load forecasting is proposed. The model uses the directly controlled parameters of the heating and cooling equipment as optimization variables, generating decisions that can be directly applied to the control system and transformed into a mixed integer linear programming model through binary expansion for online solution. In addition, for the need of online monitoring of the energy efficiency performance of systems and equipment, a corresponding energy effect attainment model is developed, which enables online early warning of abnormal energy efficiency of systems and equipment. The research has improved the efficiency of operation regulation and management of integrated systems and can provide reference for the design and construction of other projects.
