Key technologies of coordination and optimization dispatching for UHV AC&DC transmission network

Coordination and Optimization Dispatching serves the construction of Strong and Smart Grid. It is one of the key contents to protect the security and stability of large power grid. This paper analyses the characteristics of the large power grid under AC&DC hybrid operation and integration of large scale renewable energy, and proposes five major key technologies. It aims to help the operators to improve their ability so as to ensure the safe and economic operation of large power grid, and to promote the constructing of technical support system for smart grid dispatching.
