“…Boost is the basic conventional DC/DC converter, which is operated using a single switch. The boost converter [30]. consists of an inductor, capacitor, a switch and a diode for its operation as shown in Figure 5 .When the switch is turned ON, the diode gets reversed biased; thus, the current starts increasing charging the inductor; and a capacitor supports the load.…”

“…Wind speed, which is highly nonlinear, fails to provide sufficient input to the boost controller to track the maximum power point. The switching losses of boost converter are high due to frequent ON-OFF of the switch [30]. The rapid variation in wind speed also increases the stress across the switch.…”

This paper proposes an artificial neural network (ANN) based maximum power point tracking (MPPT) control strategy for wind energy conversion system (WECS) implemented with a DC/DC converter. The proposed topology utilizes a radial basis function network (RBFN) based neural network control strategy to extract the maximum available power from the wind velocity. The results are compared with a classical Perturb and Observe (P&O) method and Back propagation network (BPN) method. In order to achieve a high voltage rating, the system is implemented with a quadratic boost converter and the performance of the converter is validated with a boost and single ended primary inductance converter (SEPIC). The performance of the MPPT technique along with a DC/DC converter is demonstrated using MATLAB/Simulink.

Abstract:In this paper, a novel co-ordinated hybrid maximum power point tracking (MPPT)-pitch angle based on a radial basis function network (RBFN) is proposed for a variable speed variable pitch wind turbine. The proposed controller is used to maximise output power when the wind speed is low and optimise the power when the wind speed is high. The proposed controller provides robustness to the nonlinear characteristic of wind speed. It uses wind speed, generator speed, and generator power as input variables and utilises the duty cycle and the reference pitch angle as the output control variables. The duty cycle is used to control the converter so as to maximise the power output and the reference pitch angle is used to control the generator speed in order to control the generator output power in the above rated wind speed region. The effectiveness of the proposed controller was verified using MATLAB/Simulink software.

Summary This paper deals with the improvement of stability margin, dynamic behavior, and steady state performance of a direct current (DC) microgrid system consisting of wind energy sources, battery energy storage, and back up generation source. The DC microgrid control system should set the DC bus voltage at the allowable range and provide proper load sharing among generation sources. Accurate load sharing, proper voltage regulation, and dynamic stability of the system at presence of constant power loads (CPLs) are the main problems that may be raised in operation of DC microgrid systems. In order to address these issues, this paper proposes a generalized droop‐based compensator that not only stabilizes the DC microgrid dynamics at high penetration of CPLs, but also addresses the issues such as inaccurate load sharing and improper voltage regulation. The proposed generalized droop‐based compensator comprises three parts: the first part enhances the DC microgrid stability even at high penetration of CPL, the second part compensates the transmission lines voltage drops and improves the function of voltage regulation, and the third part performs proper load sharing among different generation sources. At the end, capability of the proposed compensator is examined by frequency response analysis and time domain simulations.
