With the fast development of multi-terminal high-voltage direct-current (HVDC) transmission system, a fast HVDC interruption technique is urgently demanded to break the short circuit current in the multi-terminal HVDC transmission system with a rapid rising rate. In this paper, an interruption scheme for HVDC based on vacuum switch and artificial current zero technique is proposed. The modularized...
With the development of modern power system, extra-high voltage (EHV) AC transmission lines are widely used. Because of large capacitive charging, long EHV AC lines may cause voltage violations in low load period. The leading-phase operation of synchronous generators and switching on shunt reactors are two common measures to relieve voltage violations in low load period. In this paper, we propose...
With the development of smart grid and the increasing penetration of intermittent generation such as wind and solar, transmission network must be operated more effectively and flexible. Transmission switching has been explored in some literature as an effective mean to reduce dispatch cost. In this paper, based on dc optimal power flow we formulate this problem as a bilevel programming problem. The...
This paper addresses actuator outages, or any actuator fault under the reconfiguration strategy. Based on the lattice structure of the set of system configurations, a frame that guarantees stability by mixing both the passive and active fault tolerance strategies is proposed. The proposed PACT designs a bank of controllers, with minimal number of control laws, and minimal instability during switching.
