“…FS‐MPC has become the most common control of power electronic converters since it offers high efficiency, low voltage and current ripples, and fast dynamic response [12]. Its robustness lies on switching states of power converters by evaluating a cost function subject to minimisation in only possible switching states [4]. FS‐MPC has been applied in most power converter systems and recently in PV system applications [3, 18].…”

“…The photovoltaic (PV) solar panels depend essentially on climatic conditions such as temperature and irradiance, where they provide limited output power with low efficiency because of their nonlinear characteristics [1,2]. To avoid this deficiency, a maximum power point tracking (MPPT) block is always connected between the PV solar panels and the load, thus playing a key role in extracting the maximum power [3,4]. Several MPPT algorithms are suggested in recent special literature works and are discussed in [5].…”

The present study sheds new light on advanced control methods of photovoltaic (PV) emulators using finite set model predictive control (FS-MPC). In the first part of the study, a predictive PV emulator (P-PVE) based on a Buck converter is proposed and tested under hard climatic conditions and load variations. The high performance of the P-PVE in terms of dynamic response, reference tracking, accuracy, simplicity, and efficiency is confirmed experimentally when compared with those of the commonly used one based PI controller. The second part of the study proposes an efficient cascaded predictive control (CPC) method applied on two topologies of PV systems, namely the stand-alone system and the grid-connected system. In each topology, the P-PVE is cascaded to a maximum power point tracking Boost converter in order to track efficiently the maximum power point. In addition to the high performance offered by the FS-MPC, the proposed control strategy allows to control all cascaded converters at the same time in one stage instead of controlling them separately, thus providing more flexibility and simple controllability. Extensive experimental results are done confirming the correctness and the effectiveness of the proposed CPC under hard climatic conditions, even in the presence of distorted grid voltage.

“…Without state‐space averaging and linearisation of the converter model, FCS‐MPC is accessible to be implemented in different power electronic topologies [16, 17]. However, because of the variable switching frequency characteristics of FCS‐MPC, the voltage/current ripples and harmonics are inevitable, which will deteriorate the lifespan of the power sources, for example, the battery and fuel cell [18]. Besides, as the converter operates at the variable switching frequency, it will increase the switching loss and may produce unpredictable resonance.…”

“…Thus, there are lower requirements on the computational ability of the CCS‐MPC controller [20]. In [18], the maximum power point tracking (MPPT) control problem is solved with a buck converter using CCS‐MPC to achieve high performance and stable operation for the photovoltaic power. In [21], a feedforward method based on CCS‐MPC is designed for a synchronous buck converter.…”

An interleaved DC–DC boost converter is widely used in DC power systems such as fuel cell systems or other systems requiring high‐power quality for increasing and stabilising the output voltage. The performance of the converter can be affected by the control strategy. In this study, a robustness continuous control set model predictive control (CCS‐MPC) for an interleaved DC–DC boost converter is proposed to achieve optimised transient dynamics and steady performance. To deal with unknown load variation and systems uncertainties, an extended Kalman observer is designed to estimate the lumped disturbance, including the load variation and unmodelled part. Based on the disturbance estimation, a dynamic current reference with the disturbance and the integrated voltage error is formulated for the optimal voltage tracking. Also, a prediction‐accuracy‐enhanced CCS‐MPC for a wide range of operation points and multi‐parameter disturbance is obtained. The proposed approach could stabilise the output voltage with good robustness under external disturbance and operation point change. Compared with other existing controllers, i.e. a proportional–integral controller, a sliding mode controller, and a finite control set model predictive controller, both the steady and transient performances are validated by a simulation and experimental test bench.

“…A buck-boost converter can be obtained by cascade connection of the two basic converters as shown in Fig. 10:• Buck converter (step-down converter)[45] • Boost Converter (step-up converter)Hence, the operation of the given circuit is explained in two modes. In first condition or mode 1, switch is turned on and the function of the diode is reverse biased.…”

This paper presents a detailed description of three methodologies to electrify the rural households of small loads with reliable and economical method using solar energy as input source of power. It is observed that high DC voltage is better and economical solution rather than AC based solar systems and low voltage DC systems. In this paper, three methodologies were analysed to select the right combination of portable converters with low prices, which may further enhance the energy access and affordability to common people. The proposed three methodologies were tested through action research in collaboration with a team of scientists and technical experts of National Institute of Solar Energy. The comparative analysis is carried out on three different converters, various kind of house loads and types of power supply i.e. AC/DC. The performance, quality and economic evaluation has been carried out with the help of MATLAB SIMULINK and other measuring instruments specific for solar photovoltaic systems. The derived results were analysed and inferences made for use in village household loads and their income groups. Further, a three-step analytical framework on village-level power energy efficient power at affordable power preposition was presented. This study will help in the designing as well as in the performance and economic evaluation of converters based on solar photovoltaic systems of different technologies.
