Abstract: This paper deeply studies the energy consumption characteristics and carbon emission status of small and micro parks, analyzes the development and application of current digital twin technology and multi-energy complementary technology, and then puts forward a new energy utilization model as "building a multi-energy complementary micro energy network in small and micro parks", and carries out field research and modeling exploration from the two dimensions of implementation methods and evaluation standards. Taking KQ Industrial Park as a sample, a multi-energy complementary micro-energy network digital twin model is built to assist dynamic scheduling through the real-time status distribution of the energy network that can be identified by the naked eye. At the same time, the benefit calculation model is used to quantitatively analyze its cost intensification and carbon value pressure drop, and evaluate the project economy from multiple parties.
