The design and implementation studies of a remote monitoring system are presented in this study. The proposed design is improved in terms of smart metering infrastructure based on current, voltage, and power measurements. The communication among the photovoltaic (PV) panels and host PC is performed by designed ZigBee transceiver system. Sensing circuits are very important devices to measure for both...
The sensing circuits are very important devices to measure for both current and voltage magnitudes of the systems. This paper presents a new sensing circuit design with significant advantages for DC voltage systems. The proposed sensing circuit is capable to measure currents and voltages by means of one current transducer and resistor network of voltage measurement. The accuracy and reliability of...
The most important parts of the smart meters are the sensing devices that are utilized to measure for both current and voltage magnitudes of the systems. Therefore, several investigations have to be carried out to improve practical applications of the smart metering systems. This paper presents a novel sensing device design for AC measurement systems. The proposed sensing system is firstly designed...
This paper proposes monitoring of the dual dc-dc converters that independently operate of each other in the same topology (Buck-Boost). The dual converter structure is proposed to implement asymmetrical string inverter that is intended to be used variously arranged PV strings. The converters are operated by independently running MPPT algorithms. The converters are supplied by programmed dc sources...
A Proportional-Integral (PI) based Maximum Power Point Tracking (MPPT) control algorithm is proposed in this study where it is applied to a Buck-Boost converter. It is aimed to combine regular PI control and MPPT technique to enhance the generated power from photovoltaic PV) panels. The perturb and observe (P&O) technique is used as the MPPT control algorithm. The study proposes to reduce converter...
This paper introduces an instant monitoring infrastructure of a renewable energy generation system that is constituted with a wind turbine and solar panel arrays. There an uncontrolled six-pulse rectifier converts ac output voltages of wind turbine to dc. The hybrid system of renewable energy sources (RES) couples generated voltages of wind turbine and solar panels on a dc-bus and supplies charge...
