A two step predictor-corrector method for voltage collapse point estimation
… voltage levels in significant part of the power system, and it is often due to system failure to satisfy reactive power demand. Voltage Collapse can lead to blackout like the one occurred in 2003 in North America. Methods for on-line voltage stability monitoring were established, and …

Improved computations of the voltage collapse point using the P-index
Online voltage stability assessment of power system is important to ensure reliability and security. Over the years, many voltage monitoring indices have been documented in the literature. These indices are designed to quantify proximity to voltage collapse. However, they all have inaccuracies when …

Performance comparison between Dual-blinder and a Phasor-based Out of Step detection functions using hardware in the loop test
… event occurs between two connected areas in the power system, the two areas should be separated before the OOS results in generation loss, equipment damage, and eventually a total black-out. This separation is achieved via the OOS function that implemented at specific transmission lines. One of …

Optimal modulation and topology design of modular multilevel converter for grid integration of solar photovoltaic systems
… out among converter topologies for medium/high-power applications. With salient features like modularity and scalability, MMC can meet the requirement of theoretically any voltage level with higher efficiency and superior harmonic performance, using converter components with reduced ratings. …

Qualitative insights into the voltage stability problem
… variation of the estimation accuracy across systems. Also, the coupled single-port method is a reformulated L-index method with no novelty on estimation, the novelty is only in the presentation. Finally, the P-index is examined and found to be more reliable if it coincides with a maximum …

Optimal power generation in microgrids using agent-based technology
The existing power grids that form the basis of the respective electrical power infrastructures for various states and nations around the world, are expected to undergo a period of rapid change in the near future. The key element driving this change is the emergence of the Smartgrid. The Smartgrid …
