CONTROL PREDICTIVO PONDERADO APLICADO A UN CONVERTIDOR MULTINIVEL MODULAR CONECTADO A LA RED (WEIGHTED PREDICTIVE CONTROL APPLIED TO A MULTILEVEL CONVERTER CONNECTED TO THE NETWORK)
Resumen
Resumen
En este artículo, se presenta el control de un convertidor multinivel modular (MMC, por sus siglas en inglés) de baja potencia que trabaja como inversor monofásico conectado a la red, con dos submódulos. El control utilizado es un control basado en un modelo predictivo ponderado (WMPC, por sus siglas en inglés) basado en una función de costo para seleccionar el mejor caso de conmutación que permita controlar la corriente de salida, al mismo tiempo que minimiza la fluctuación de los voltajes de los capacitores y la corriente circulante del inversor. La intención de este trabajo es detallar el funcionamiento de los MMC para facilitar su comprensión, además de servir como una guía para el diseño de un controlador basado en un modelo predictivo del sistema.
Para comprobar el funcionamiento del sistema, se diseñó y simuló en PSIM.
Palabras Clave: Control, Inversor, Modular, Multinivel, Predictivo.
Abstract
This paper presents the control of a low power MMC that works as a single-phase inverter grid-connected, with two sub-modules. The control used is a Weighted Model Predictive Control (WMPC) based on a cost function to select the best switching case to control the output current while minimizing fluctuation of capacitor voltages and inverter circulating current. This work in intended to describe in a detailed form the MMC, but also to provide a design guide for predictive controllers.
To evaluate the operation of the proposed system, it was designed and simulated in PSIM.
Keywords: Control, Inverter, Modular, Multilevel, Predictive.
