“…This is in contrast to the case of the micro inverter, whose output is directly connected to the grid. Positioning the central inverter in between the array and the grid results in numerous advantages, as mentioned in the Introduction [70,72,73]. The conventional non-isolated DC-DC converter, such as buck, boost, and buck-boost is commonly used as the main building block of the DCO [70,72,[74][75][76].…”

This study reviews the hardware approach to mitigate the effects of module mismatch in a grid-connected photovoltaic (PV) system. Unlike software solutions, i.e. the maximum power tracking algorithm, hardware techniques are well suited to enhance energy yield because of their inherent ability to extract energy from the mismatched module. Despite the extra cost of the additional circuitry, hardware techniques have recently gained popularity because of their long-term financial benefits. Notwithstanding the growing interest in this topic, review papers that provide updates on the technological developments of the three main hardware solutions, namely micro inverter, DC power optimizer, and energy recovery circuits, are lacking. This is in contrast to software solutions, which have had a considerable number of reputable reviews. Thus, a comprehensive review paper is appropriate at this juncture to provide up-to-date information on the latest topologies, highlight their merits/drawbacks, and evaluate their comparative performance.

Abstract: The utility of electric power plays a major role in economic development of a country. However, the demand for electrical energy goes on increasing every day. In order to meet out the demand for electricity, Renewable Energy Source (RES) has been identified as the alternate for electricity generation. Among the various RES, PV system has added consideration throughout the world due to its easy accessibility, boundless nature and of low maintenance cost. Since the voltage obtained from PV is not suitable for high power applications, a DC/DC step up converter is introduced. This converter should have reduced output voltage ripple which is an important factor that influences the overall performance of PV system. Hence, this work studied about the different topology of converter suitable for PV systems to have a better efficiency.

Summary This paper presents a robust and optimal output‐voltage tracking controller for a DC‐DC buck converter. A fractional‐order proportional‐integral (FPI) controller is primarily used to eliminate the steady‐state error and damp the oscillations. In order to improve the error convergence rate of the response, the FPI controller is augmented with a single‐input fuzzy‐logic based precompensator stage. The fuzzy precompensator aggregates the information regarding the error and error derivative using the signed‐distance method. The derived aggregated signal is used to infer logical control decisions based on a predefined one‐dimensional rule base. The simplification yields shorter computation time and a piecewise linear control surface that improves the system's immunity against exogenous disturbances and unprecedented nonlinearities. The error derivative is indirectly computed by measuring the capacitor current in real time. This modification further enhances the computational efficiency, offers minimum‐time transient recovery, and compensates the hysteresis effect rendered by parasitic impedances. The controller gains are optimally selected using the particle swarm optimization algorithm. Credible hardware‐in‐the‐loop experiments are conducted to validate the time optimality and robustness of the proposed controller. The experimental results clearly demonstrate the significant improvement rendered by the proposed controller in the system's reference tracking performance, disturbance‐rejection capability, and transient recovery time.
