“…The space Equations (18) are called the "perturbed Port-Hamiltonian model" of a physical system [13][14][15][16]21,29,35] for the αβ or dq frames because we can substitute (17) in (18). The vector of the input variables m αβ,dq and the vector of disturbance variables d αβ,dq is Equation (19).…”

“…A passivity-based controller [13][14][15][16][17][18] was developed using an interconnection and damping assignment (IDA-PBC), which enables the control of a three-phase inverter to be decoupled in the dq frame [27][28][29]. For the presented inverter model cases, we assume that the coefficients of the matrixes J αβ,dq , R αβ,dq , G αβ,dq , and D αβ,dq do not depend on the state variables.…”

“…Thereby, the main aim of this paper is to provide guidelines and a design methodology on how to apply the simplest PBC approach for a three-phase VSI (simpler than e.g., the Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) idea presented in [27]) while maintaining a reasonable compromise between the ideal theory and the customer demands (with the more enhanced direct control of the output voltage than presented in [22]). The results of the modulator saturation effect, the problem of the restriction of the modulation index, the problem of the influence of the scaling factors in the measuring tracks on the PBC controller gains, and the final adjustment of the controller gains to reach the lowest distortions of the output voltage for the standard loads were not discussed yet [27][28][29]. The aim of the paper is to present a PBC version that can be easily implemented in a standard modern microcontroller delivering the pulse width modulation (PWM) signal with the acceptable high switching frequency.…”

This paper presents a passivity-based control (PBC) design methodology for three-phase voltage source inverters (VSI) for uninterruptable power supply (UPS) systems where reduced harmonic distortions for the nonlinear load, reduced output voltage overshoot, and a restricted settling time are required. The output filter design and modification for efficient control and existing challenges with the assignment of scaling coefficients of the output voltage, load, and inductor currents are addressed and analyzed. Notably, special attention is given to the modulator saturation issue through implementing an accurate converter model. Applications of the two versions of PBC in three-phase voltage source inverters using stationary αβ and rotating dq frames for a constant frequency of the output voltage are presented. Furthermore, the influence of the PBC parameters on the power converter performance is investigated. A comparative simulation and the experimental results validate the effectiveness of the presented passivity-based control design methodology.

This paper describes the application of the Port Controlled Hamiltonian Network for Modelling and Control of non-linear power system dynamics. Goal of this work is to propose a methodology for system level design for power electronics driven electrical networks able to guarantee large signal stability. Starting from a model-level modular approach, the system is defined using the interconnection concept. The paper focuses on a DC micro-grid scenario where several converters interact with a lumped load. Contrary to previous work, the load is modelled as a Constant Power Load (CPL) introducing new challenges in terms of system stability.

“…Previous studies of this problem propose different solutions to minimize the presence of reactive power in the Electric Distribution System [22][23][24][25][26][27][28][29][30], as well as to minimize the costs generated by its presence [31,32]. Traditionally, according to these studies, the presence of reactive power is exclusively associated with the presence of the elements mentioned above.…”

Reactive power is an important parameter in electrical power systems since it affects the efficiency of the system because it is not useful energy. It decreases the power factor of the system and limits the ability of generators to deliver useful power. It is therefore necessary to understand and correctly measure the phenomenon of reactive energy in three-phase systems. In this paper, we analyze reactive power in linear and unbalanced three-phase systems using the Unified Theory of Electrical Power and the Institute of Electrical and Electronics Engineers Standard 1459-2010 (IEEE Std. 1459-2010) to obtain expressions for reactive power in balanced and unbalanced systems and noting that there are terms that exist only for unbalanced systems. Analysis of the measurements carried out led us to identify the existence of two components of reactive power—that due to reactive elements, and that caused by unbalances in the system. Knowing the causes that generate reactive power, it is possible to act more effectively on the problem and therefore achieve a more sustainable generation of electric power and a lower environmental impact.
