For islanded microgrids, droop-based control concepts have been developed both in single and three-phase variants. The three-phase controllers often assume a balanced network; hence, unbalance sharing and/or mitigation remains a challenging issue. Therefo... see more

This paper presents a new control strategy for isolated micro-grids including wind turbines (WT), fuel cells (FC), photo-voltaic (PV) and battery energy storage systems (BESS). FC have been used in parallel with BESSs in order to increase their lifetime a... see more

AC microgrid mainly comprise inverter-interfaced distributed generators (IIDGs), which are nonlinear complex systems with multiple time scales, including frequency control, time delay measurements, and electromagnetic transients. The droop control-based I... see more

Este estudo objetiva identificar  a forma de avaliação de desempenho utilizada para os controllers em empresas que adotam sistemas de remuneração por recompensa. Foi realizada pesquisa descritiva a partir de um levantamento, tendo como população as 5... see more

In this article a control analysis in state variables is presented, applied to the nonlinear Magnetic Levitation system (MLS), which consists in keeping objects suspended in the air without any mechanical contact through the interaction of magnetic force.... see more

Studies on controllership activities interrelated with other sciences, such as psychology and sociology, favor more holistic knowledge about this organizational area. This study aims to verify the impacts of the implementation of the International Account... see more

Currently, the worth of power generation on the basis of renewable sources is rapidly growing. Correspondingly the microgrids and the DG units are impressed the researchers for their peculiar features. Power sharing is the major concern when various DGs a... see more

The paper deals with problems of computer-aided design of controllers for systems of stabilization of information-measuring devices operated on vehicles of the wide class in difficult conditions of disturbances action. Algorithms of the robust parametrica... see more
