There is no uniform definition of the smart grid at the current academic level. It is based on power flow and information flow, covering the power system. Including: power generation, transmission, substation, distribution, electricity, scheduling and other aspects of the overall system solutions. Compared with the existing power grid, the smart grid reflects the remarkable characteristics of high integration of power flow, information flow and business flow. Its advanced nature and advantages are mainly reflected in:
1. With a strong grid infrastructure and technical support system, it can withstand all kinds of external disturbances and attacks, and can adapt to the access of large-scale clean energy and renewable energy. The strength of the power grid has been consolidated and improved.
2. Information technology, sensor technology, automatic control technology and grid infrastructure are organically integrated to obtain panoramic information of the power grid, and timely discover and anticipate possible faults. When a fault occurs, the grid can quickly isolate the fault and achieve self-recovery, thus avoiding the occurrence of large-scale power outages.
3. Wide application of technologies such as flexible AC and DC transmission, network plant coordination, intelligent dispatching, power storage, and distribution automation, making grid operation control more flexible and economical, and adapting to a large number of distributed power sources, microgrids and electric vehicles. Access to charging and discharging facilities. The comprehensive application of communication, information and modern management technology will greatly improve the efficiency of power equipment use, reduce power loss, and make grid operation more economical and efficient.
4. Establish a two-way interactive service mode, users can understand the power supply capacity, power quality, electricity price status and power outage information in real time, and rationally arrange the use of electrical appliances; power companies can obtain detailed power consumption information of users and provide them with more value-added services.
Plastic Package Diode.Among the electronic components, a device having two electrodes allows only the current to flow in a single direction, and many uses apply its rectification function. The Varicap Diode is used as an electronic adjustable capacitor. Most of the diodes have a current directionality that we often call the "Rectifying" function. The most common function of a diode is to allow only current to pass in a single direction (referred to as forward bias) and block in the reverse direction (referred to as reverse bias). Therefore, the diode can be thought of as an electronic version of the check valve.
