| Summary: | Integrated Energy Systems (IESs) present complex structures and diverse operational scenarios that require sophisticated Integrated Energy Management Systems (IEMSs). However, current IEMS are often faced with challenges such as difficulty in universal energy calculation, low adaptability of complex system models, and limited flexibility for multiple scenarios. Universal modeling addresses these challenges by reducing implementation costs, enhancing system flexibility, and promoting wider IEMS adoption. Energy efficiency analysis is the cornerstone of comprehensive IEMS evaluation. Universal modeling of energy efficiency analysis is essential for reducing construction costs and improving energy efficiency management. This study proposes multiple universal energy efficiency analysis models for energy production and consumption processes, leveraging a black-box modeling approach to capture the commonalities and individualities of various energy management objects. For Energy Production Units (EPUs), an energy efficiency analysis calculation model considering comprehensive correction and an energy efficiency evaluation model considering level indicator limits are introduced. Three models are introduced for Energy Consumption Units (ECUs): a usage statistical model considering allocation, exclusion, and sharing; an energy consumption per product model based on product conversion; and an energy performance evaluation model based on regression analysis. The proposed universal energy efficiency analysis models were successfully applied to multiple real-world engineering projects, and the results demonstrate their versatility and effectiveness. The proposed models significantly reduced IEMS construction costs, with an average reduction of 63% in labor costs. |
