In this work, we show a new methodology for automatic supervision and fault detection of PV Systems, based mainly on the analysis of the power losses. This methodology includes parameter extraction techniques to calculate main PV system parameters from monitoring data [1-2], taking into account the real irradiance and module temperature, allowing simulation and evaluation of the PV system behav...

As the penetration of photovoltaic (PV) systems on building rooftops increases, the accumulated effect of the rooftop PV power outputs on electric network operation is no longer negligible. Energy storage resources (ESRs) have been used to smooth PV power outputs, particularly when building load becomes low. In commercial buildings, the batteries of plug-in electric vehicles (PEVs) can be regar...

This paper presents a case study of photovoltaic (PV) system design at Hwangji Youchang facility in Korea, to power an electrical aerator for natural purification of acid mine drainage. The aerator was designed as 13 units with air flow capacity of 60 L/min at the oxidation pond by considering the characteristics of incoming drainage. Site evaluation was conducted to identify a suitable locatio...

For many years, the photovoltaics (PV) community has relied on the concept of energy payback time (EPT) as a means of quantifying the ratio of energy generated from a PV panel or system over its lifetime, compared to the energy that was required to fabricate it. Few other energy technologies are so judged and this paper argues that the EPT concept is obsolete, misleading and may possibly even c...

The objective of this contribution is to present a new numerical approach for a complete design, optimum sizing, cost estimation (capital & $/kWh) and also evaluating the performance of solar photovoltaic/battery/diesel hybrid power systems. The world-wide demand for solar photovoltaic energy systems has grown steadily over the past 15 years. The need for reliable and low cost electric power in...

A TRNSYS component (Type 262) has been written to simulate a concentrating PV/Thermal collector. The component is based on a dynamic model of a concentrating PV/Thermal collector, which includes thermal capacitance effects, and detailed equations describing the temperature dependent energy flow between the collector and surroundings. The CHAPS system, a 30x concentration parabolic trough PV/The...

In this paper, we propose an analysis of the structure and functioning in the Pspice simulation and experiment of a discretized photovoltaic (PV) system. This system is formed by two DC/DC Boost converter connected in series. Its role is to transfer electrical energy from two PV generators through two adaptation stages (upper and lower stages). We proposed a circuit control of the power switch ...

This research deals with the Non-Isolated Bidirectional Dc-Dc Converter (NBDC) control unit development for a smart power supply system using personal residential Photovoltaic-Power Conditioning Subsystem (PV-PCS), the results of circuits evaluation, and isolated PV-PCS operation connected battery storage (Electric vehicle storage etc.). The smart power supply system using the existing resident...

According to diffusion theory, opinion leaders play an important role in the diffusion of new technologies through interpersonal communication with potential adopters. This study investigates the role and utility of opinion leadership in photovoltaic (PV) system diffusion. Specifically, the study proposes, examines, and considers the implications of the hypothesis that there is a positive relat...

Objective(s): Drug-induced atrial fibrillation (AF) is considered an adverse effect of chemotherapeutic drugs. AF is a crucial risk factor for stroke, heart failure, myocardial infarction, and mortality. Pulmonary veins (PVs) are considered triggers inducing AF, and the sinoatrial node (SAN) may modulate PV activity and participate in AF genesis. AF was associated with...
