Smart grid refers to a fully automated power supply network in which every user and power node is monitored in real time, and the two-way flow of current and information from the power plant to the user-side appliances is guaranteed.
Through the extensive application of distributed intelligence, broadband, and the integration of automatic control systems, the smart grid ensures real-time market transactions and seamless connection and real-time interaction between members on the grid.
From a technical point of view, the smart grid has three levels of meaning. The first is to use sensors to monitor the operating conditions of key equipment in power generation, transmission, distribution, and power supply in real time, and then collect and integrate the obtained data through the network system.
Finally, through the analysis and mining of data, the optimal management of the entire power system is achieved.
The characteristics of the smart grid are:
1) Recovery,
through real-time control of the power grid operating status, timely detection, rapid diagnosis and elimination of hidden troubles, and avoid large-scale power outages.
2) Safety.
It can respond well to natural disasters, external damage and computer attacks, ensure the safety of people, equipment, and power grids, and automatically restore the operation of the power grid.
3) Efficient,
can optimize resource allocation, improve equipment transmission capacity and utilization, timely dispatch between different regions, and balance power supply gaps.
4) Compatible and compatible with various types of equipment,
including centralized large power supply, distributed power generation and renewable energy, to meet the requirements of the harmonious development of electricity and the natural environment, and the social economy.
5) Interact with users friendly,
realize intelligent interaction with customers, meet customer needs with the best power quality and power supply reliability, achieve seamless connection between system operation and wholesale and retail power markets, and at the same time better stimulate power through market transactions
Market players participate in the safety management of the power grid, thereby improving the safe operation of the power system.
