Evaluation of Integrated Energy System Configuration Strategy

Ensuring China’s energy security and building a green, low-carbon, clean and efficient energy supply system are the top priorities to promote energy development in the new era. The integrated energy system can realize the cascade utilization of energy and couple renewable energy. It has the advantages of clean, efficient and flexible under the appropriate configuration and operation scheme. In order to deeply explore the type selection and configuration of the coupled renewable energy system, this paper constructs an indicator system from the three levels of economy, system security and environment, gives weight to the indicator system, and uses the average ranking method to comprehensively rank the evaluation results of four multi-criteria optimization decision-making methods, including simple weighting method, superior and inferior solution distance method, harmony analysis method and multi-criteria optimization compromise decision-making method, so as to determine the optimal configuration scheme and promote the substantial and stable development of the integrated energy system.
