Energy Efficiency Assessment of Integrated Energy System in Substation Area

The substation area integrated energy system provides energy support for the normal operation of the substation, and its energy consumption level has a significant impact on the grid loss. This paper analyzes the distribution of energy consumption of substation from three aspects: equipment, substation electricity and office electricity. The basis, index and weight of energy efficiency assessment are established by analytic hierarchy process, and a scientific and complete energy efficiency assessment of substation station area integrated energy system is formed. The system provides a reference for energy saving and consumption reduction in substations. Finally, the effectiveness of the proposed method is verified by an example.
