The solar photovoltaic (PV) systems are facing serious problems due to unavoidable losses in their system, leads to more devation of output power from the input power level. This effect is known as a mismatch effect and is available in PV systems. Many losses are encountered in PV system and it is difficult to minimize such losses. In this paper, the influence of thermal effect on the solar PV ...

Photovoltaic (PV) system output electricity is related to PV cells’ conditions, with the PV faults decreasing the efficiency of the PV system and even causing a possible source of fire. In industrial production, PV fault detection is typically laborious manual work. In this paper, we present a method that can automatically detect PV faults. Based on the observation that different faults will ha...

Hybrid power system can be used to reduce energy storage requirements. The influence of the Deficiency of Power Supply Probability (DPSP), Relative Excess Power Generated (REPG), Energy to Load Ratio (ELR), fraction of PV and wind energy, and coverage of PV and wind energy against the system size and performance were analyzed. The technical feasibility of PV-wind hybrid system in given range of...

-This paper presents a steady-state model of a gridconnected photovoltaic (PV) system using Electromagnetic Transient Program (EMTP) MODELS. Recently the PV system has been introduced in power systems. The previous PV generation was used only to supply small loads or for home use. Nowadays, installations of grid-connected PV systems are increasing due to several advantages compared to standalon...

This project proposes a voltage stability for an interline photovoltaic (I-PV) system. In an I-PV system, the inverters in a PV plant are reconfigured in such a way that two or more distribution networks / feeder are interconnected. The I-PV system is operated as a flexible ac transmission system (FACTS) device STATCOM to regulate the point of common coupling voltage on either feeder. One of th...

Background Pharmacovigilance (PV) data are crucial for ensuring safety and effectiveness of medicines after drugs have been granted marketing approval. This paper describes the PV systems of India, Uganda and South Africa based on literature and Key Informant (KI) interviews and compares them with the World Health Organization’s (WHO’s) minimum PV requirements for a Functional National PV Syste...

In this paper we present a new system called CDB-PV that uses constraint databases (CDBs) for program verification (PV). The CDB-PV system was implemented in C++ and tested on several sample programs that are difficult to verify using other methods. The CDB-PV system also runs efficiently for the sample programs. The CDB-PV approach is similar to abstract interpretation but it allows non-convex...
