The line commutated converter (LCC) based HVDC transmission is often adopted to transmit the large capacity of renewable energy, however, it is threatened by several critical issues, such as, commutation failures (CFs). In order to reduce CFs and improve

General treatment to calculate the Thevenin equivalent circuit
American Journal of Physics, 1978The method to calculate the Thevenin (or Norton) equivalent circuit of networks containing controlled current and/or voltage sources is identical to the method used with purely passive circuits if the fundamental concept of equivalence of networks is properly understood.

Dynamic Voltage Instability Identification of Power System using Thévenin Equivalent Method
Students Conference on Engineering and Systems, 2020Voltage instability is one of the key issues in continuously evolving power systems. In this paper, the Thevenin's equivalent method is combined with a static voltage stability index (VSI) to identify the critical load demands of the power system.

Thevenin equivalent circuit for the study of high photovoltaic penetration in distribution grids
IEEE PES ISGT Europe 2013, 2013The electricity grid is unidirectional operating in a passive way and consequently it is not yet ready to accept high penetration of renewable energy sources (RES). Further research is required to assess the impact of distributed Photovoltaic (PV) generation on power quality and establish the necessary measures for the restructuring of the electricity ...

Detection and Classification of Faults in Solar PV Array Using Thevenin Equivalent Resistance
IEEE Journal of Photovoltaics, 2020Detecting fault in a solar photovoltaic (PV) array in the presence of protection diodes (bypass and reverse blocking) is complex. This is because variations in the electrical parameters (due to a fault) are often not distinguishable from one type of ...
