PROJECT TITLE :
Control of Single-Phase Power Converters Connected to Low-Voltage Distorted Power Systems With Variable Compensation Objectives
This paper presents a flexible control technique for power electronics converters, that will perform as an energetic power filter, as a local power supply interface, or perform both functions simultaneously. Thus, it can compensate for current disturbances while simultaneously injecting active power into the electrical grid, transforming the facility converter into a multifunctional device. The most objective is to use all the capacity out there in the electronic power converter to maximise the advantages when it's put in within the electricity grid. This objective is achieved by using the orthogonal current decomposition of the conservative power theory. Each current part is weighted by compensation coefficients ($k_i $), which are adjusted instantaneously and independently, in any percentage, by means of load conformity factors ( $lambda _i $), therefore providing online flexibility with respect to the objectives of compensation and injection of active power. Finally, simulated and experimental results are presented to validate the effectiveness and performance of the proposed approach.
