Reliability Assessment And Promotion Strategy For Multi-type Integrated Community Energy System

With the aggravation of environmental pollution and the depletion of fossil energy,the comprehensive distribution and utilization of electricity,gas,cold,heat and other energy sources is the focus in the energy field.The Integrated Community Energy System realizes the coupling and crossover of energy in source,network,load and storage.By coordinating the deployment and supply of different energy supply links,the comprehensive utilization efficiency of energy can be improved It has a good development prospect.However,with the increasing types of energy and load in the integrated energy system,how to make full use of the resources allocated in the energy system and consider the inherent characteristics of the energy system to optimize the scheduling of the integrated energy system,and accurately assess the reliability of the integrated energy system,is the key to the scientific planning and efficient operation of the integrated energy system.Therefore,this paper mainly studies the reliability evaluation and upgrading of multi-type Integrated Community Energy Systems such as urban and rural..Firstly,it introduces the research status and development trend of Integrated Community Energy System at home and abroad,and analyzes the regional integrated energy system.The basic structure is divided into urban-type Integrated Community Energy System and rural-type Integrated Community Energy System according to the development status in the country.Secondly,a reliability assessment model considering the dynamic characteristics of heat load is put forward for the urban-type Integrated Community Energy System.By establishing the dynamic change process of thermal load,the load reduction of thermal load is combined with the dynamic process of thermal load.It is better to meet the actual situation and improve the accuracy of Integrated Community Energy System reliability assessment.Finally,for the rural-type Integrated Community Energy System developed under the background of electric energy substitution,a voltage optimization control strategy based on self-regulation of electric heat pump is proposed.It gives full play to the potential of electric heat pump regulation in the rural distribution network area.The optimization model is established and verified by actual examples.
