What is the Energy System?
 

                      

                            Energy System      

The energy system can be divided into two sub-systems: transportation and fixed.

The supply, demand, and distribution facilities in each energy system are highly compatible. But they're freelance of every different.

Introduction edit

We need to conduct in-depth research on some important research areas, such as improving energy efficiency, and organically integrating power transmission, distribution, and storage systems with various renewable energy sources to improve future energy supply conditions. Technologies such as biofuels and solar energy are still in the research and development stage and cannot truly meet human energy needs. Therefore, continuous innovation must be made to improve and perfect existing technologies or develop new technical solutions.

The energy system is the entire process of transforming natural energy resources into specific energy service forms (effective energy) required for the production and life of human society. It is a subsystem of the socio-economic system abstracted out for the study of energy conversion and usage laws. It usually consists of a series of technological links and equipment such as exploration, mining, transportation, processing, distribution, conversion, storage, transmission and distribution, use, and environmental protection.

Energy System Engineeringedit

The system plan and supporting implementation process of energy construction and development of energy system engineering. That is, to implement best rules, best style, and best management for the complete method of energy from resource development to conversion and use, to create an Associate in Nursing energy construction system that meets the wants of economic and social development. my country established the Energy System skilled Committee in 1981. In addition to its national energy symposium organization, also organized national energy model research and energy soft science research. Characteristics and conditions of energy system engineering. It absorbs the new achievements of system theory, operations research, and other disciplines, and makes overall inspections of the multiple components of energy interconnection, interdependence, and interaction, and reasonable arrangements so that each part of energy construction is subject to the overall goal and achieves the best Effect. 

(1) Scientific nature. Through rigorous methods and relatively accurate data, quantitative and qualitative analysis of energy issues, scientific energy development plans, clarify the tasks of each stage of energy construction and coordinate the development of energy and various sectors of the national economy. 

(2) Practicality. Since the 1960s, industrially developed countries have applied systems engineering (SE) methods to seek the overall optimization of energy; applied value engineering (AE) methods to minimize the cost of completing the same "function". Energy system engineering is the embodiment of modern economic management and a necessary condition for the development of the energy industry.

Energy system engineering is an optimization technology for organization management and operation management for planning, research, design, manufacturing, testing, and application of energy systems. It is a branch of systems engineering. Guided by system viewpoints and systems thinking, use trendy arithmetic, system technology, and data processor technology to determine energy models, conduct simulation analysis of energy systems, and set up the combination, potency, and improvement of energy development and utilization. 

The main content includes energy forecasting, planning, planning, evaluation, feasibility study, and various system analysis, etc. Energy system engineering plays a very important role in formulating national or regional energy plans, evaluating energy policies, strengthening scientific management of energy at all levels, and promoting the effective use of energy. 

Overall energy systematic

The overall energy system is a system designed to supply and distribute electricity, heat, and cooling requirements for a building, a complex of buildings, or a factory based on a single fuel input.

Energy system management edit

Energy system management is a systematic and scientific management activity formed during the decision-making and implementation process of energy development and utilization. A system may be an assortment of interconnected things. Management is to guide and control things to make them run in an orderly manner. Energy system management is to achieve unified coordination and overall efficiency of energy management objectives, management content, management forms, and management methods. It is the application of system theory in energy work. As a large-scale system, energy management generally includes four systems, namely, the management of energy material resources, energy human resources, energy information resources, and energy materials and equipment.

The goals, tasks, and basic requirements of energy system management are to make the rational development and utilization of energy resources, reasonable energy investment, energy-saving implementation, energy environmental protection, energy innovation, and new energy development, etc., to achieve the overall balance of energy. The mutual promotion and common development of energy and other economic sectors. Management forms include economic, technical, administrative, and legal aspects. Energy system management has reached a high level in developed countries, and it is a social factor for developed countries to achieve high energy efficiency.

Energy system efficiency edit

Energy system efficiency is the overall calculation of the efficiency of all links in the energy system, including development, processing, conversion, transportation, storage, distribution, and utilization. Reflects the effective and rational use of energy in the energy system. It is affected by many factors such as nature, technology, economy, management, and society.

Energy system modeled

The energy system model is a mathematical model that studies the relationship between energy demand and supply, taking various energy sources as objects. Utilize the substitutable characteristics of various energy sources, put various energy sources together for overall research, carry out reasonable distribution of various energy types, select reasonable energy technology, and rationally transform energy equipment, to obtain the best balance between supply and demand. Energy system. The energy system model plays a very important role in formulating a country or region’s energy development plan, energy-saving plan, and evaluating energy distribution policies, energy technology policies, and energy technology equipment policies. 

The energy model system is also called the "energy model system". A system composed of several relatively independent and interrelated models related to energy technology and economy. It has gradually become popular since the mid-1970s. Generally, it is coupled by several models such as the objective economic model, industrial sector association model (ie input-output model), energy system model, the energy industry, and market model. 

Through the information transmission and feedback between the various models, multiple iterations can achieve the balance of the entire system and provide the best solution. The energy model system can be used to comprehensively and quantitatively study the energy economic problems of a country or region, and it is a powerful tool for energy system analysis.

Source system network diagrammed

The source system network diagram is a simplified and abstract graphical model describing the energy system based on the actual energy flow of each link in the whole process from mining to the final consumption of various energy sources. It is a network flow diagram showing the structural relationship of the energy system. The arrow on the line segment indicates the direction of energy flow; above and below the line segment are marked process energy flow, process efficiency, process cost, and process environmental pollution factors. 

The energy system network diagram can describe the overall picture of the energy system of a country, region, department, or enterprise, accurately express the various components and main characteristics of the system, and can be used for quantitative analysis. It is an important tool for establishing energy models and performing system simulation analysis.
