The key technologies of the intelligent microgrid mainly include the following:
1. New energy renewable energy power generation technology
At present, the smart microgrid is mainly based on a variety of renewable energy sources. The power input is mainly composed of photovoltaic, wind, hydrogen, natural gas, biogas and other mature power generation technologies.
2. Key technologies for energy storage
Energy storage is an indispensable part of the micro-grid. It can play the role of cutting peaks and filling valleys in the micro-grid, greatly improving the utilization efficiency of intermittent energy with the continuous development of technology. The current energy storage mainly includes battery energy storage, flywheel energy storage, superconducting magnetic energy storage, and supercapacitor energy storage. At present, the more mature energy storage technology is lead-acid battery, but it has short life and lead pollution, and high storage in the future. The marketability of graphene batteries with energy, low cost and high quality performance will bring spring to the energy storage industry. Energy storage technology is currently a high development cost, and all countries in the world are tackling this technology, but all have a common purpose, that is, to achieve "low cost + high energy storage."
3. Intelligent microgrid energy optimization scheduling technology
Different from the traditional power grid dispatching system, the intelligent microgrid dispatching system belongs to the horizontal multi-energy complementary optimization scheduling technology, which can fully exploit and utilize the complementary alternatives of different energy sources, which can not only realize the output of heat, electricity and cold, but also Realize energy exchange between light/electricity, heat/cold, wind/electricity, and direct/alternating. All kinds of energy in the source-storage-loading process are less hierarchical and orderly cascaded optimal scheduling, achieving the best energy utilization efficiency.
4. Intelligent microgrid protection and control technology
There are multiple power sources and multiple loads in the smart microgrid. The changes in load and fluctuations in the power supply need to be adjusted and controlled by the energy storage system or the external power grid. The regulation, switching and control of these power supplies is done by the microgrid control center. In addition to monitoring the power parameters, switching states, and power quality and energy parameters of each new energy generation system, energy storage system, and load, the microgrid control center also needs to improve energy conservation and power quality.
The intelligent microgrid is a new type of network structure that is developing rapidly. The smart microgrid and the large grid exchange energy. The two sides are spare each other, which is an effective way to realize the active distribution network, thus improving the reliability of power supply. . The quiet rise of smart micro-grid will fundamentally change the way traditional power grids cope with load growth, which has great potential in reducing energy consumption and improving power system reliability and flexibility. At present, microgrid technology has become a new direction of power system reform, and the market-oriented process will inevitably accelerate the performance of key equipment.
