Abstract
The safe and stable operation of the energy system is the top priority of the world in the industrial field. The energy integrated system optimizes the system through multiple channels and cascade utilization of energy, which greatly improves the utilization rate of energy and provides a convenient way for the development of low-carbon society. In this paper, the composite integrated energy system model is constructed through the analysis of the structure of the integrated energy system. On this basis, a coordinated optimal scheduling method for integrated energy system with multiple energy stations is proposed, which takes the system operation economy as the goal. The case simulation results show that the coordinated operation of energy stations can greatly improve the stability and economy of the hybrid integrated energy system.
Highlights
The existing literature separates optimization scheduling from the configuration optimization
Reference [1,2] carryout comprehensive modelling of electric power, natural gas and thermal system, analyses the model of energy network, and carries out energy flow analysis on this basis; Reference [3] adopts the multi-criterion partial pressure method to analyse the micro-cooling and heating power systems under different climatic conditions; In reference [4,5], a multi-user optimal configuration model with energy storage is established aiming at configuration economy
Based on the concept of complex integrated energy, it will interconnect all kinds of new energy sources and optimize the allocation and operation of resources, to realize the complementation of integrated energy, and to maximize the benefits in real life, compared with existing literature, considering the operation economy, environmental protection and energy saving of the scheme, in order to achieve energy allocation and operation optimization
Summary
The existing literature separates optimization scheduling from the configuration optimization. Reference [6-8] research on home energy efficiency management strategies based on distributed photos tatting power stations and energy storage systems. Based on the concept of complex integrated energy, it will interconnect all kinds of new energy sources and optimize the allocation and operation of resources, to realize the complementation of integrated energy, and to maximize the benefits in real life, compared with existing literature, considering the operation economy, environmental protection and energy saving of the scheme, in order to achieve energy allocation and operation optimization. The "horizontal multi-purpose complementation" in the energy Internet refers to the complementary coordination among various energy resources in distributed energy stations, highlighting the "substitution". In order to improve the utilization rate of resources, the "source-network-load-storage" coordinated development concept is adopted in the process of distributed energy scheduling.
