What are the grid-connected technical support systems?

Grid-connected technical support system includes: data integration, assessment management, auxiliary service compensation, model management, settlement management, information release and system management. Grid-connected technology refers to the technical measures to ensure the safe and reliable operation and qualified power quality of distribution network with distributed power sources. The traditional distribution network is a passive network, which distributes electric energy to users and the electric energy flows in one direction. With the access of distributed power supply, distribution network has become an active network of two-way power flow, which also brings technical problems such as voltage fluctuation, misoperation or refusal of relay protection. Influence of distributed power access on distribution network, active distribution network planning, protection and control of distributed power grid connection, active distribution network protection, active distribution network voltage control, active distribution network power quality control, distributed power dispatching and management, etc. , is the hot spot of power technology research.
