0 Preface Solar energy gathering and power generation are the most ideal new energy sources. To promote the development of renewable energy and new energy technologies and related industries in China, according to the national long-term development plan for renewable energy, the National Development and Reform Commission decided to implement the specialization of high-tech industrialization of renewable energy and new energy. Among them, the industrialization of solar collectors, power generation components and control systems has become one of the key areas for the special support of renewable energy and new energy high-tech industrialization. Therefore, the maximum development and utilization of solar energy will be the development direction of human new energy use. Of course, to make solar energy collectors and generators truly reach the practical level, 1. To increase solar heat collection, photoelectric conversion efficiency and reduce costs, 2. To achieve solar energy collector, power generation with the current heating, power supply network. In recent years, with the promotion and development of solar thermal utilization technologies, energy-saving and low-carbonization technologies based on distributed solar energy collaborative energy cascade utilization as a platform, and heterogeneous three-network integration of smart wireless sensor networks, broadband networks, and mobile networks. Internet of Things transmission technology, using cloud computing, data mining, and precise energy-saving management technologies as platforms to remotely manage and monitor energy-saving and emission-reduction projects for commercial, industrial and agricultural subjects, and in a modular, standardized, network-based technology innovation platform On the basis of this, it has successfully developed a distributed solar energy collaborative energy cloud monitoring platform technology for low-carbon energy management. 1 Distributed Energy System Features 1. Directly according to the needs of local users, located near the user, to simplify the energy transmission links, thereby reducing energy delivery costs, while increasing the safety of the user's energy supply. 2. The system is constrained by the needs of users. Compared with the traditional centralized energy supply system, it is medium and small capacity. 3. With the development and maturation of the economy and different energy technologies, there are more and more alternative technologies available. 4. By selecting the appropriate technology and optimizing the integration of the system, you can better meet the various requirements of the user (eg, high efficiency, reliability, economy, environmental protection, sustainable development, etc.) and achieve multiple functional goals. The newest distributed energy technology in the world utilizes advanced, efficient, intelligent, clean and reliable energy systems such as natural gas, solar energy and geothermal. 2 Basic Concepts 2.1 Distributed Cooperative Energy It refers to a small-scale energy system device that provides power generation and heat supply by modularizing and integrating one or more energy sources and complementing one another, and approaching the construction of small users or unit users. Its combination with energy control management and storage systems (such as superconducting energy storage) provides users with high-quality, clean, reliable, and stable energy service integration technology. 2.2 Collaborative Control System Different from the traditional system solutions, the cooperative control system uses multiple control points as the optimal control target of the system. It does not only control the individual devices in isolation, but fully considers the interaction between the various parts of the distributed system and the environment. Influences such as weather and seasons, starting from the overall system, and using a unified and integrated artificial intelligence optimized cooperative control scheme, truly allow the system to operate in the most energy-efficient and efficient manner. 2.3 Cloud Energy Conservation Supervision The Internet-based distributed energy cascade utilization system is a user-friendly nearest-connection system consisting of a gas pipeline network, a low-voltage power grid, hot and cold water networks, and information. The network-based cloud layout energy-saving monitoring system integrates the intelligent operation and settlement of networks. , redundancy adjustment and system fault tolerance optimization. Multiple Energy Systems Integrate Energy-Saving Cloud Optimization—Jointly optimize various energy systems, such as: Integrate distributed energy with traditional energy, and jointly optimize; or Integrate distributed energy systems with ice storage systems. The joint re-optimization will optimize the integration of micro-turbine and heat pump systems, as well as the optimization and integration of solar energy and distributed systems, so as to achieve the purpose of complementing each other and give full play to the comprehensive advantages of each system. Distributed energy systems have become increasingly popular in the world of energy because of their flexible and variable loads, lower initial investment, reliability of power supply and heating, small transmission losses and complementary renewable energy applications suitable for synergies. The more attention is paid, the various countries in the world are paying different attention to the construction of a distributed collaborative energy system, actively piloting, earnestly preparing for legislation, and stepping up the development of supporting related equipment. Distributed collaborative energy systems overcome some of the weaknesses of traditional systems compared to traditional power systems that concentrate power generation and heating over long distances, and become indispensable beneficial supplements. The organic combination of the two is the power supply for the new century. The development direction of the thermal industry and energy industry. 3 project application With the rapid development of solar hot water systems, system safety control has also received more and more attention. In a large number of control facilities investment, intelligent auxiliary energy control will be mainly used. In the solar and gas, heat pump auxiliary energy intelligent collaborative control system, the use of solar thermal energy and gas, heat pump auxiliary energy intelligent collaborative energy-saving control technology, suitable for all kinds of solar water heating systems have intelligent demand for intelligent control. Realize intelligent and integrated control system for gas and heat pump auxiliary energy. At present, the solar integrated control business based on intelligent auxiliary energy control is still in the initial stage of exploration. It not only needs to focus on solar thermal control technology, but also needs to provide a complete intelligent auxiliary energy control integrated solution. The project application basic service platform construction should follow The following principles: 1. Reliability The stable and reliable operation of the system is a prerequisite for the system's practicality. The system is required to have high stability. In the event of system failures and emergencies, it has measures to guarantee normal operation. 2. Ease of use The system should reduce the workload of system maintenance personnel as much as possible. After a short period of training, the general staff can grasp the method of use of the system. This is for the practical needs of the system during its use. After the system is delivered and used, it should be convenient for all kinds of routine maintenance work, and it can easily perform software reconfiguration, intelligent early warning and monitoring, hardware spare parts replacement, and software system upgrade. 3. Extensibility Expansion capability is one of the most important principles of the intelligent auxiliary energy control application basic service platform. As a basic service platform for intelligent auxiliary energy control applications, the platform should have sufficient and flexible intelligent adaptation capabilities, scalability capabilities, and automatic upgrade capabilities. Fully consider the standardization of interfaces and the standardization of protocols. Therefore, although solar energy companies at home and abroad want to develop control products that adapt to intelligent auxiliary energy as the research focus of the company, there are many problems that have not yet been well solved due to the research and development and industrialization of solar thermal and auxiliary energy intelligent collaborative systems. The group's modular intelligent cooperative control system for solar energy, gas and heat pump auxiliary energy provides a feasible platform solution for solving the above problems.
