Research on Energy Efficiency Evaluation of Independent Integrated Energy System

With the development of society, human's demand for energy sources has been increasing, so the integrated energy system (IES), which can effectively reduce energy consumption and improve energy efficiency has been widely used for that non-renewable fossil energy is running out. As the ocean has been deeply developed and utilized, the independent integrated energy system (TIES), which is closely related to the marine production process such as offshore oil platforms, oceanic islands and large ships has been gradually developed. In order to better plan and schedule the system which is an area far from the coast and needs a variety of energy sources like electric heating, how to reasonably evaluate the IES has become a key issue(1). Based on the existing evaluation system of large-scale IES, this paper constructs an energy efficiency evaluation system of the IIES, and establishes an energy efficiency evaluation method on the basis of combining the analytic hierarchy process (AHP) with hundred-mark system. Taking an offshore oil platform as an example, the energy efficiency evaluation method of the IIES is calculated and analyzed.
