“…Due to the non-linear relationship between the output current and the voltage of the PV array and the rather complex relationship between the input and output characteristics of the IWPT converter, it is a challenge to maintain both the maximum power point tracking (MPPT) and the maximum efficiency point tracking (MEPT) simultaneously for the overall PV-IWPT system. In terms of the implementation of the MPPT operation, some PV systems integrated with the IWPT converter has proposed and emerged recently [20], [21], [22], [23], [24], in which an additional DC-DC converter was applied between the PV array and the inverter of the IWPT converter to implement the MPPT control algorithm, thus increasing the cost. Additionally, keeping the characteristic of the PV array under various irradiation conditions including non-shading condition, uniform shading condition and partial shading condition, the pure PV system usually requires the adoption of various maximum power tracking algorithms [25], [26], [27], which targets for the minimization of the cost and the maximization of the conversion efficiency of the PV array.…”

Unfortunately, most of the PV-IWPT systems in the existing literature [20], [21], [22], [23], [24], [28], [29] did not consider the shading issues. The wireless power transfer system interfacing with a DC bus in [29] did not take into account the shading conditions as well.…”

“…Besides, load impedance mismatch also causes a significant transfer efficiency degradation for the IWPT converter [30], [31], [32], [33]. Unfortunately, all of the aforementioned PV-IWPT systems did not consider load impedance matching in their designs, thus the transfer efficiency is not optimized in [20], [21], [22], [23], [24], [28], and [29]. Since the load variation under shading conditions is normally wide, it is challenging to maintain the operation of the MEPT by using a single-stage IWPT.…”

A rooftop photovoltaic (PV) system is a significant solution of building-integrated centralized generation in the low-voltage (LV) DC grid. The drilling-free rooftop PV-inductive wireless power transfer (PV-IWPT) system for the LVDC grid can reduce the installation and post-maintenance costs, with the elimination of physical cable connections and preventing breaking of thermal bridge and rain penetration between the rooftop and the inside of the building. Moreover, it has inherent isolation properties between the input and the output terminals. However, it is challenging for the PV-IWPT system to simultaneously achieve the maximum power point tracking (MPPT) for the PV panels and the maximum efficiency point tracking (MEPT) for the system even under diverse irradiance conditions. In this paper, we propose an efficient PV-IWPT system, which consists of a series-series IWPT converter, driven by the PV panels and loaded by the LVDC grid directly. Moreover, we apply in the proposed system a particle swarm optimization with an auxiliary Perturb and Observe (P&O) algorithm and a load matching method without wireless feedback communication to realize MPPT and MEPT in the overall PV-IWPT system simultaneously. Finally, we analyze theoretically and verify experimentally the proposed PV-IWPT system in a 500-W experimental platform under different irradiance conditions.INDEX TERMS Low-voltage DC grid, photovoltaic, maximum power point tracking, inductive wireless power transfer, maximum efficiency point tracking.

“…Their experimental results assumed that the converted energy efficiency from solar radiation can be used to avoid faults at different output power levels. A maximum power point tracking (MPPT) DC–DC converter using wireless power transmission was proposed by Zheng et al [ 20 ]. Their experimental findings showed that adding the MPPT to an inverter resulted in a significant energy transfer to the load.…”

This paper originally presents a photovoltaic (PV) evaluation and fault detection (PVEFD) system for PV applications based on the Internet of Things (IoT) technology. The PVEFD system consists of an STM32F103C8T6 chip with a 32-bit Arm Cortex-M3 reduced instruction set computer (RISC) and 12-bit resolution analog-to-digital converter (ADC) to measure important parameters of PV applications, such as solar irradiance as well as the back-surface cell temperature, operating voltage, and output current of PV devices. The measured data of irradiance as well as back-surface cell temperature and operating voltage of PV devices are then fed into a built-in PV model in the on-chip Arm Cortex-M3 RISC for hardware-in-the-loop (HIL) simulation to obtain the simulated output current and power of PV devices. The resulting data are transmitted to a cloud server for remote monitoring and automatic warning function through a Raspberry PI 3 module and WiFi network. The simulation results are compared with in-field measurement data from PV modules and displayed on a human–machine interface (HMI) and an Android app. The results of the study illustrated that the proposed system features high accuracy and sufficient confidence. Furthermore, the fault detection function through the built-in HIL simulation function in PV systems was validated. Therefore, the proposed system is a small, compact, and cost-effective HIL-on-chip machine for remote surveillance of PV power systems.
