This paper discusses the power electronics interfaces and controls for a microgrid paradigm with both DC and AC links. The microgrid is an integrated energy delivery system that consists of interconnected distributed energy resources and controllable loads and can operate in parallel with or isolated from the main power grid. The proposed approach provides a general framework to aggregate a wide range...
The objective of this paper is to theoretically investigate the application of superconducting magnetic energy storage (SMES) system in damping power system low-frequency electromechanical oscillations. In the paper, the SMES system is studied in the context of a single-machine infinite-bus (SMIB) power system. The mathematical model of the SMIB power system including a SMES unit is established, and...
Power system stabilizers (PSSs) are used to provide damping torque for the synchronous generators to suppress low frequency oscillations present in the power system by generating supplementary control signals for the excitation system. Strong nonlinearity and dynamics exist in the power system. Numerous previous techniques have been proposed to design PSSs but many of them are synthesized based on...
