“…In References [13,14] is presented a simple way to build a non-isolated hybrid energy storage system, connecting one of the sources directly while linking the other utilizing a DC-DC converter; yet this method does not permit the adjustment of the DC bus voltage. Another technique is to link each of the sources with the DC bus with an individual converter as presented in References [15][16][17][18]. In this way, it is possible to manage the DC bus voltage but it is an expensive solution due to the utilization of multiple converters.…”

Electric Vehicles (EVs) are an alternative to internal combustion engine cars to reduce the environmental impact of transportation. It is common to use several power sources to achieve the requirements of the electric motor. A proper power converter and an accurate control strategy need to be utilized to take advantage of the characteristics of every source. In this paper is presented a novel topology of a multiple-input bidirectional DC-DC power converter to interface two or more sources of energy with different voltage levels. Furthermore, it can be used as a buck or a boost in any of the possible conversion of energy. It is also possible to independently control the extracted power in each source and any combination of the elements of the system can be used as source and destiny for a transfer. Finally, the interaction with the grid is possible. The operation, analysis and design of the converter are presented with different modes of power transfer. Simulation results are shown where the theoretical analysis of the converter is validated.

“…In this paper, a new control strategy based on the flatness properties is proposed to control of a variable-speed wind energy system connected to the grid, shown on Fig.1. This method has been used to manage the energy in an electrical hybrid system [3,4], to control a permanent magnet synchronous motors in [5,6] and to control induction machines in [7,8], In [7], it has been shown that this type of control can improve performance of the system in transient state in comparison with the traditional vector control method. The main advantage of this control method is the ability of predicting behavior of the system state variables in the transient state as well as the steady state.…”

In this paper, a new nonlinear control method based on differential flatness is applied to a high-power wind energy conversion system connected to the grid. The control system is done by planning the appropriate trajectories on components of the output variable vector of the system. The main advantage of the proposed method is control of the system even during the transient state as well as the high performance.The studied system includes a three-bladed horizontal wind turbine and a permanent magnet synchronous generator (PMSG) which is connected to the grid through a back to back converter and a filter. In order to study performance of the control strategy, a random profile of the wind speed has been used. The simulation results obtained in Matlab/Simulink environment are presented to validate efficiency of the control strategy.

“…Hence, the algorithm commutation is necessary when the operating mode changes which may lead to a "chattering" phenomenon. In [10][11], a flatness based method is used to control a FC/SC hybrid system without the algorithm commutation. This method is useful when explicit trajectories are required.…”

In this paper, an intelligent control strategy based on combination of the "flatness based control technique" and the "perturbation and observation (P&O) MPPT algorithm" is developed and investigated to control a hybrid electric energy source (HEPS). This EHPS is composed of a fuel cell system (FC) and a solar panel (SP), as the main source and a supercapacitor bank (SC), as the auxiliary sources. The main property of this strategy is that the system power flow is managed in different operating modes with the same control algorithm (without algorithm commutation). The power flows between the fuel cell, the SC is controlled by the flatness based control technique while a P&O MPPT technique is developed to control power of the SP. To validate performance of the proposed control of the HEPS, the simulation results are presented.
