Standalone DC microgrids as complementarity dynamical systems: modeling and applications
journal contribution
posted on 2023-06-09, 17:20 authored by Arash Moradinegade DizqahArash Moradinegade Dizqah, Alireza Maheri, Krishna Busawon, Peter FritzsonIt is well known that, due to bimodal operation as well as existent discontinuous differential states of batteries, standalone microgrids belong to the class of hybrid dynamical systems of non-Filippov type. In this work, however, standalone microgrids are presented as complementarity systems (CSs) of the Filippov type which is then used to develop a multivariable nonlinear model predictive control (NMPC)-based load tracking strategy as well as Modelica models for long-term simulation purposes. The developed load tracker strategy is a multi-source maximum power point tracker (MPPT) that also regulates the DC bus voltage at its nominal value with the maximum of ±2.0% error despite substantial demand and supply variations.
