The smart grid consists of eight main features that functionally describe the characteristics of the grid, rather than the specific technology of the final application, which form the complete picture of the smart grid. The smart grid is a self-healing grid. In essence, self-healing is the "immune system" of the smart grid. The self-healing grid conducts continuous online self-assessment to predict possible problems with the grid, identify existing or evolving issues, and immediately take steps to control or correct them. To ensure the reliability, safety, power quality and efficiency of the power grid. Smart grid incentives and include users. From the perspective of the smart grid, the user's needs are completely another manageable resource, which will help balance the supply and demand relationship and ensure the reliability of the system; from the user's point of view, power consumption is an economical Choosing, by participating in the operation and management of the grid, correcting the way in which it uses and purchases electricity, thereby achieving tangible benefits. The smart grid will defend against attacks. Smart grid security strategies will include deterrence, prevention, detection, and response to minimize and mitigate the impact on the grid and economic development. Smart grids provide power quality that meets the needs of users in the 21st century. Power quality indicators include voltage offset, frequency offset, three-phase imbalance, harmonics, flicker, voltage dips, and surges. Smart grids will alleviate power quality events from transmission and distribution systems. Monitor the basic components of the grid with its advanced control methods to quickly diagnose and accurately propose solutions to any power quality event. In addition, the design of smart grids should also consider the reduction of power quality disturbances caused by lightning, switching currents, line faults and harmonic sources, as well as the latest research results of power technology using superconductivity, materials, energy storage and improving power quality to solve electrical energy. Quality issues. The smart grid will allow access to a variety of different types of power generation and energy storage systems. The smart grid will make the power market boom. Through the interaction of supply and demand in the market, the smart grid can most effectively manage parameters such as energy, capacity, capacity change rate, and power flow blockage, reduce trend blockage, expand the market, and bring together more buyers and sellers. Smart grids optimize their asset applications to make operations more efficient. For example, through dynamic assessment techniques to enable assets to perform at their best, they can be used under greater load by continuously monitoring and evaluating their capabilities.
