Abstract
The monitoring system in photovoltaic (PV) power plants is very important and urgent in some cases for analyzing, troubleshooting and in decision making issues. This paper proposes very simple, low cost, high reliability, and high precision PV monitoring system. The proposed system is composed of a laptop connected to very cheap microcontroller board via serial cable. All the sensors and actuators are emulated in a prototype board that interfaced to the microcontroller system. A graphical user interface (GUI) program is developed in LabVIEW to monitor all the collected data in the laptop monitor and controls the system actuators via the microcontroller. An assembly program is written on the microcontroller board to scan and acquire all required data from sensors, transfer it to laptop for monitoring and then storing it for PV system documentation. The experimental results show that the proposed monitoring system is very robust and the control signals are very accurate. The system is very reliable, precise, cheap and more flexible for use in large scale photovoltaic power plant monitoring.

A stand-alone power system based on a photovoltaic array and wind generators that stores the excessive energy from renewable energy sources (RES) in the form of hydrogen via water electrolysis for future use in a polymer electrolyte membrane (PEM) fuel cell is currently in operation at Neo Olvio of Xanthi, Greece. Efficient power management strategies (PMSs) for the system have been developed. The PMSs have been assessed on their capacity to meet the power load requirements through effective uti...

This paper presents an adaptive artificial neural network (ANN) for modeling and simulation of a Stand-Alone photovoltaic (SAPV) system operating under variable climatic conditions. The ANN combines the Levenberg–Marquardt algorithm (LM) with an infinite impulse response (IIR) filter in order to accelerate the convergence of the network. SAPV systems are widely used in renewable energy source (RES) applications and it is important to be able to evaluate the performance of installed systems. The ...

APV-wind hybrid model has been developed to simulate a stand-alone power system with battery storage. The model has been applied to a typical consumer peak load of one kW at a remote community in Bangladesh. Using the model, different parameters are evaluated for one-year of full operation of the system. An economic analysis has also been undertaken to assess the feasibility of such a system at the location considered.

This paper presents a review of existing dynamic electrical battery models and subsequently describes a new mathematical model of a lead acid battery, using a non-linear function for the maximum available energy related to the battery discharge rate. The battery state of charge (SOC) is expressed in a look-up table relative to the battery open circuit voltage (VOC). This look-up table has been developed through low discharge experiments of the battery modelled. Further, both the internal resista...

Abstract A valve regulated lead acid (VRLA) battery simulation model is an invaluable tool for the standby power system engineer. The obvious use for such a model is to allow the assessment of battery performance. This may involve determining the influence of cells suffering from state of health (SOH) degradation on the performance of the entire string, or the running of test scenarios to ascertain the most suitable battery size for the application. In addition, it enables the engineer to assess...

Within the scope of full-scale energy modeling of a hybrid wind / photovoltaic system coupled to the network, our focus herein lies in a battery set-up that makes use of the CIEMAT model. The implementation and energy-based analysis of this model are conducted with emphasis on the continuous estimation of battery capacity. A measurement vs. model results comparison is then performed under actual operating conditions.

The PVB stand-alone system composes a PV array, storage battery and other balance of system components. The PV array is an independent system, where the array voltage and current are changed according to the change either in the insolation level or in the cell temperature. On the other hand the battery has a constant voltage with a small voltage drop or over voltage according to the discharging or charging currents and its SOC. In most of the PVB systems control, the current signals are used as ...

This study aims to design and develop the prototype models of the smart photovoltaic system blind (SPSB). To achieve this objective, the study defined the properties in three ways: (i) the photovoltaic (PV) panel; (ii) the tracking system; and (iii) the monitoring system. First, the amorphous silicon PV panel was determined as a PV panel, and the width and length of the PV panel were determined to be 50 mm and 250 mm, respectively. Second, the four tracker types (i.e., fixed type, vertical singl...

With the growing demand of energy across the globe, different sources and alternatives of energy has been invented or improved but PV system has been proven to be the best energy generating source. This type of dependency on solar energy is seen due to its perpetual source of energy and negligible side effect. But the efficiency of solar cell is affected due to many internal factors (due to component used in manufacturing) as well as external/environmental factors (wind, dust, humidity, location...
