           Solar and multi-scenario fusion solar power supply system is a field full of potential. It combines photovoltaic technology and multi-scenario applications to provide stable, reliable and environmentally friendly power supply for various scenarios. The following are some key features and application scenarios of photovoltaic and multi-scenario fusion solar power supply system:             1. Residential and architectural fields: Photovoltaic and building integration (BIPV) is an important form of integration between photovoltaic and architectural fields. By installing photovoltaic panels on buildings, solar energy is converted into electrical energy to provide power supply for buildings. This method is not only beautiful, but also reduces the energy consumption and carbon emissions of buildings, achieving green buildings and sustainable development.           2. Agricultural field: The integration of photovoltaic and agricultural fields can realize the "agricultural light complementary" mode. Installing photovoltaic panels above the farmland and carrying out agricultural production below not only makes full use of land resources, but also improves the efficiency of agricultural production. At the same time, photovoltaic panels can also provide power support for agricultural irrigation, breeding, etc., and promote the modernization of agriculture.           3.

Public facilities: Photovoltaics are also widely used in public facilities. For example, installing photovoltaic panels in public places such as parks, squares, and schools can provide power support for lighting, monitoring and other equipment, reducing energy consumption and carbon emissions. In addition, photovoltaics can also be combined with energy storage technology to provide a stable power supply for public facilities in remote areas.           5. Energy storage field: With the development of energy storage technology, the integration of photovoltaics and energy storage technology is becoming closer and closer. By storing the electricity generated by photovoltaic panels, it can provide power support for various scenarios in insufficient light or at night. This can not only solve the intermittent and volatile problems of photovoltaic power generation, but also improve energy efficiency and reduce dependence on traditional electricity.           In short, photovoltaics and multi-scenario integrated solar power supply systems have broad application prospects and potential. With the continuous advancement of technology and the continuous expansion of the market, it will play an increasingly important role in various fields and promote the transformation and sustainable development of the global energy structure.

The key technologies of smart microgrids mainly include the following: (I) Renewable energy generation technology At present, smart microgrids are mainly based on a variety of renewable energy sources, and the power input is mainly photovoltaic, wind power, hydrogen energy, natural gas, biogas and other mature power generation technologies. (I) Key technologies of energy storage Energy storage is an indispensable part of microgrids. It can play a role in peak shaving and valley filling in microgrids, greatly improving the utilization efficiency of intermittent energy. With the continuous development of science and technology, the current energy storage mainly includes battery energy storage, flywheel energy storage, superconducting magnetic energy storage, and supercapacitor energy storage. The more mature energy storage technology is lead-acid battery, but it has the problems of short life and serious lead pollution. In the future, the marketization of high energy storage, low cost, and high-quality performance graphene batteries will bring spring to the energy storage industry. The current development cost of energy storage technology is relatively high. Countries around the world are working on this technology, but they all have a common goal, which is to achieve the goal of "low cost + high energy storage". (II) Smart microgrid energy optimization dispatching technology Different from the traditional power grid dispatching system, the smart microgrid dispatching system belongs to the horizontal multi-energy complementary optimization dispatching technology, which can fully explore and utilize the direct complementary substitutability of different energy sources, and can not only realize the output of heat, electricity and cold, but also realize the energy exchange of light/electricity, heat/cold, wind/electricity, direct/alternating current. The stratification of various energy sources in the source-storage-load links realizes orderly cascade optimization dispatching to achieve the best energy utilization efficiency. (III) Smart microgrid protection and control technology There are multiple power sources and multiple loads in the smart microgrid. The changes in loads and fluctuations in power sources need to be regulated and controlled by the energy storage system or the external power grid. The regulation, switching and control of these power sources are completed by the microgrid control center. In addition to monitoring the power parameters, switch status, power quality and energy parameters of each new energy generation system, energy storage system and load, the microgrid control center also needs to save energy and improve power quality.
