“…This excess is absorbed by the SC since it does not reach its maximum SOC "Usc<Uscmax". During the periods [0, 0.2], [5, 8.9], [10.9, 11.9], [15,19.1] and [23.6, 24.6] the SC discharge mode is activated (mode 2). In this mode there is a lack of production "Pg<PL".…”

This paper deals with the problems of intermittency of primary source of wind energy and the external disturbances. Subsequently, a power management and a robust control of a standalone energy production unit are presented. This production unit comprising a variable speed wind turbine coupled to a Permanent Magnet Synchronous Generator (PMSG) and a module of Super-Capacitors (SC) that is considered as an Energy Storage System (ESS). This unit feeds a three-phase load by means of an inverter and an RLC filter. In order to assure a control strategy which has a very good performance despite the high nonlinearity of wind systems and an intermittence form of wind power, a second-order sliding mode control based on a super-twisting algorithm is applied to a PMSG. Then, a power management strategy is applied to the SC using a buck-boost converter according to load instructions and wind speed fluctuations. The response of the power algorithm enables to ensure the power flow exchange between the production unit and the power consumers and to protect the ESS against overcharge and excess discharge to ensure safe operation. Finally, using PI controllers, the inverter adjusts the capacitors voltages and currents at the output of the RLC filter with the nominal frequency and voltage. The simulation results show the robustness of the implanted control strategy.

“…The extracted electrical power from PMSG is injected to the DC-link via an uncontrolled rectifier and a boost converter. The benefits of this structure are its simplicity and cost reduction [29]. The control of the boost converter attempts to achieve the maximum power point by utilizing the lookup table of wind turbine characteristics, whereas the control of buck/boost converter attempts to keep the DC-link voltage constant and regulates the battery current on two sides.…”

Along with the great benefits of utilizing renewable energy (e.g., wind energy) in the power system, there are also some issues, such as increasing the uncertainty and reducing the system inertia. Communication-based centralized control has started to play a significant role in reacting to the aforementioned issues, especially for relatively small systems, such as microgrids. In this context, in this paper, an enhanced communication-based hierarchical control for a dual mode wind energy conversion system-based microgrid is modeled and investigated. The primary stage utilized the P-V/Q-f droop method, which is the preferred droop method to be used in microgrids when the line impedance is mainly resistive. The secondary stage relied on an enhanced methodology for compensating the deviations of voltage and frequency and improving the performance of the microgrid during small and large signal disturbances. Moreover, as this microgrid operates in a dual mode, the mode transition cases from grid-tied mode to autonomous mode and vice versa have been addressed. Thereafter, an improved control scheme for the unplanned outage transition and a modified control scheme for the pre-synchronization and reconnection transition were proposed. Finally, the proposed work was evaluated by the simulation results in MATLAB environment.

“…In this last case, two of the most widely employed nonlinear control techniques, i.e., feedback linearization (FBL) and sliding modes (SM) have been employed respectively in [21][22][23]. In [22], the attention is concentrated on the control of the machine side converter (MSC) and the application of the particle swarm optimization for the MPPT, while in [21] a unified control scheme for both the machine and grid side converter (GSC) is presented.…”

The problem of model and parametric uncertainties typical of model-based control techniques like FBL is overcome in [23] with a method able to handle disturbances. However, whereas references [21,22] suffer from robustness problems, the control strategy proposed in [23] is very demanding in terms of the design of the WTG controller.…”

This paper focuses on the modeling of wind turbines equipped with direct drive permanent magnet synchronous generators for fundamental frequency power system simulations. Specifically, a procedure accounting for the system active power losses to initialize the simulation starting from the load flow results is proposed. Moreover, some analytical assessments are detailed on typical control schemes for fully rated wind turbine generators, thereby highlighting how active power losses play a fundamental role in the effectiveness of the wind generator control algorithm. Finally, the paper proposes analytical criteria to design the structure and the parameters of the regulators of the wind generator control scheme. Simulations performed with Digsilent Power Factory validated the proposed procedure, highlighting the impact of active power losses on the characterization of the initial steady state and that the simplifying assumptions done in order to synthesize the controllers are consistent with the complete modeling performed by the aforementioned power system simulator.
