“…For cost-effective panel-level monitoring, voltage metering and current metering use a voltage divider and a shunt resistor, respectively. The voltage divider is composed of two resistors, as in an earlier study [17], and current metering typically utilizes one shunt resistor and one operational amplifier (OP-AMP), indicating that the voltage divider and the shunt resistor enable a cost-effective metering circuit. The next section also describes the details of the metering circuit.…”

“…This lowpass filter suppresses high-frequency noise components out of the low-frequency band, where the slowly varying components of the voltage and current exist. The WPMM uses 0.001 as the time constant τ of the low-pass filter related to the cutoff frequency, as reported in a previous study [17].…”

“…Thus, the expressions in (14) and (15) should be modified to compensate for error effects to enable more accurate metering. When variables that reflect the effects of errors are applied, (14) and (15) can be, respectively, modified to become (16) and (17).…”

Given the rapidly increasing market penetration of photovoltaic (PV) systems in many fields, including construction and housing, the effective maintenance of PV systems through remote monitoring at the panel level has attracted attention to quickly detect faults that cause reductions in yearly PV energy production, and which can reduce the whole-life cost. A key point of PV monitoring at the panel level is cost-effectiveness, as the installation of the massive PV panels that comprise PV systems is showing rapid growth in the market. This paper proposes an implementation method that involves the use of a panel-level wireless PV monitoring module (WPMM), and which assesses the cost-effectiveness of this approach. To maximize the cost-effectiveness, the designed WPMM uses a voltage-divider scheme for voltage metering and a shunt-resistor scheme for current metering. In addition, the proposed method offsets the effect of element errors by extracting calibration parameters. Furthermore, a design method is presented for portable and user-friendly PV monitoring, and demonstration results using a commercial 30-kW PV system are described.

This paper presents an economic analysis of the effectiveness of Dynamic Reconfiguration Systems (DRS) for PV plants in dependence of the incentive policies offered by several countries of the European Community. This evaluation has been achieved by means of the NPV (Net Present Value) and through the comparison between Bulgaria, Romania, Greece and Croatia. From the obtained results, it can be stated that the adoption of reconfiguration systems, in certain cases, can be a convenient solution

The main objective of this paper is to study and analyse the voltage output waveform of a multilevel inverter, to suggest a new approach for harmonic mitigation improving the converter performance. These last type of converters represent a new technology in the field of DC/AC electrical energy conversion, presenting advantages respect to the traditional converters. In fact, the multilevel power converters present a low harmonic content and a high voltage level. The paper considers a five-level single-phase cascaded H-bridge inverter and fundamental frequency modulation techniques. The voltage waveform analysis has allowed to identify a working area of the converter where there are lowest values of the considered harmonic amplitude. The simulated behaviour of the model of the converter, with the logic piloting gate signals, has been obtained in Matlab-Simulink environment
