Operation Optimization Strategy of Park-level Integrated Energy System Considering Energy Efficiency
The present work analyzed the influence of energy utilization efficiency on the operation of integrated energy system,and proposed a multi-objective operation optimization strategy considering energy utilization efficiency.First the cold-head-power-integrated energy system was modeled based on the typical park-level integrated energy system.Second the use of energy utilization efficiency in quantifying energy utilization level of the integrated energy system was proposed. Third the optimization model with multiple objective functions for operating economy and energy utilization efficiency was converted into a single-objective model by maximizing the weighted membership function.Finally the case verification on an actual integrated energy demonstration park in North China was carried out to check the effectiveness of the proposed operational optimization strategy.
