The access and management of dispersed energy resource(DER) in active distribution network(ADN) enable coordinate voltage control (CVC) to control voltage actively in distribution system. This paper highlights the impacts of DER on the voltage profile and control strategies of existing distribution network. Accordingly the CVC control framework and strategy in ADN is proposed, which is to make full...
Division of distribution control area is the foundation of operation, marketing, maintenance and fault analysis. By comprehensively analyzing the critical demands of the operation, control and management in distribution network, distribution control area is modeled based on common information model (CIM), in order to improve the efficiency of the fault diagnosis and optimal dispatching. Taking advantage...
To verify the rationality of networking and the real-time reliability of network transmission for the process level in smart substation, this paper proposes a method of modeling and simulating for smart substation based on OPNET, which models the key network equipments after analyzing the simulation requirement of process level network in smart substation. And several networking modes and optimization...
Aimed at the applied limitations of traditional Spare Power Automatic Switchover inside of substation using in chain-mode grid model,an new technology of Area Spare Power Automation Switchover was researched. The basic theory and process was discussed while the key points also proposed. Through demonstrated the cooperation with traditional Spare Power Automation Switchover, auto-reclosing, security...
With the development of power grid, traditional Spare Power Automatic Switchover became far from satisfaction of the grid operation. Area Spare Power Automatic Switchover(ASPAS) System, supported by automation, communications and internet technology, must go through rigorous testing before the closed-loop operation. The digital simulation technology of ASPAS test system acquires actual network collusion...
