Power-Controlled Hamiltonian Systems: Application to Electrical Systems with Constant Power Loads
We study a type of port-Hamiltonian system, in which the controller or disturbance is not applied to the flow variables, but to the systems power—a scenario that appears in many practical applications. A suitable framework is provided to model these systems and to investigate their shifted passivity properties, based on which, a stability analysis is carried out. The applicability of the result...
متن کاملBifurcation Analysis of a DC-DC Bidirectional Power Converter Operating with Constant Power Loads
Direct current microgrids (MGs) are an emergent option to satisfy new demands for power quality and integration of renewable resources in electrical distribution systems. This work addresses the large-signal stability analysis of a DC-DC bidirectional converter (DBC) connected to a storage device in an islanding direct current (DC) MG. This converter is responsible for controlling the balance o...
متن کاملDetection of Disturbing Loads in Power Systems using Non-Active Power
This paper detects the disturbing loads in distorted and/or unbalanced three phase three wire power system. It is based on the simultaneous measurement of four non-active power quantities, which are found on the IEEE Std.1459-2000 method. It allows, achieving better knowledge of the power system when both harmonic distortion and un-balance are present. The proposed method requires only the fund...

متن کاملModeling and Stability Analysis of AC-DC Power System with Controlled Rectifier and Constant Power Loads
-Power converters with their controls normally behave as a constant power load. This load can significantly degrade the system stability. Therefore, the system dynamic model is very importance because it can be used for stability analysis. It is well known that power converter models are time-varying because of their switching behaviours. This paper presents the DQ modeling method to eliminate ...
