Abstract
With the development of society, people’s demand for clean energy is constantly increasing, and it is in this context that the concept of integrated energy systems was born. As the main component of the energy internet, the integrated energy system is now considered to be the main form of energy operation in the future of human society, and the synergistic optimization of different forms of energy can better enhance energy utilization and achieve the effect of 1+1>2. The planning and design of the comprehensive energy system will involve the data collation and characteristic analysis of energy types, so many factors should be taken into account when planning the specific scheme and operation of the comprehensive energy system’s general access, different types of energy forms should be fully considered in the planning of the characteristics of the energy, such as easy control of electrical energy, convenient production, but it is difficult for us to make a decision within a short period of time under normal circumstances.
Highlights
Integrated Energy System (IES) is not a new concept[1], because there are already practices related to the cooperation and optimization of different forms of energy[2], such as Combined Cooling Heating and Power (CCHP) [3], which is to achieve the purpose of cutting peaks and filling valleys through the cooperative optimization of heat and electricity in CCHP[4], improve the utilization efficiency of energy and make the conversion between different forms of energy more flexible[5]
The energy storage technology in the comprehensive energy system mainly serves different forms of energy, the main technologies used are generally cold storage technology, heat storage technology, gas storage technology, electricity storage technology, four kinds of energy storage technology applied in the comprehensive energy system, energy storage is efficient and easy to convert and cross-use between different forms of energy[12]
An integrated energy system planning and optimization model is developed based on a fixed investment, with the aim of achieving the lowest overall cost, lowest carbon emissions, and highest overall energy efficiency when the integrated energy system is oriented towards ubiquitous access
Summary
Integrated Energy System (IES) is not a new concept[1], because there are already practices related to the cooperation and optimization of different forms of energy[2], such as Combined Cooling Heating and Power (CCHP) [3], which is to achieve the purpose of cutting peaks and filling valleys through the cooperative optimization of heat and electricity in CCHP[4], improve the utilization efficiency of energy and make the conversion between different forms of energy more flexible[5]. As one of the important links in the strategic goal of "three types, two networks, world class", the Ubiquitous Electricity Internet of Things (IoT) focuses on each link of the power system and fully applies modern information technology such as mobile internet and artificial intelligence[8]. Advanced communication technology enables the interconnection and human-computer interaction of all aspects of the power system, providing intelligent and convenient services for the planning of the integrated energy system[9]
