![]() ![]() ![]() A significant advantage of using batteries in a PVWPS is that they ensure the availability of water at certain times, such as at night, during periods of low solar radiation, and on cloudy days in places where water storage tanks are unavailable. Some references can be found in (2 cases in 108 references), in (1 case in 49 references), and in (3 cases in 97 references). Although battery-coupled PVWPS solutions are described in, to the authors’ knowledge there are few studies in the literature on this topic. ![]() Photovoltaic water pumping systems (PVWPSs) are an alternative to fossil fuel pumping facilities because, among other reasons, their costs have decreased to levels where PV solutions are cheaper than buying energy from the local power network distributors. New trends in grid-connected PV systems include the use of ESSs, such as lithium-ion batteries (LIBs), to increase the share of self-consumed energy in domestic and industrial sectors and to solve problems related to the integration of distributed generation (DG) systems based on REs with conventional electricity grids (these problems include frequency control, active power control, reactive power control, dynamic grid support ). ESSs are expected to develop considerably in the coming years since both wind and PV are intermittent sources, and battery storage and pumped hydro energy are emerging as the most implemented solutions for adjusting the profiles of energy generation and energy demand. Wind and photovoltaic (PV) technologies are experiencing worldwide growth due to the low cost of the energy they generate, and they are currently leading the fight against climate change. Renewable energies (REs) and energy storage systems (ESSs) can reduce greenhouse gas emissions as well as dependence on fossil and nuclear energy. Finally, the initial results of the monitoring system are presented, and the possible uses of the acquired data and potential users of the system are identified and described.Ĭoncern about climate change is growing, and a transformation in the current energy model is needed to achieve a sustainable and efficient energy mix. csv files can be created that include the desired variables with a defined time interval and with the desired data granularity. Data processing is complemented with a configurable data exporter program that enables users to select and copy the data stored in InfluxDB. Data storage is performed in a server using InfluxDB for open-source database storage and Grafana as open-source data visualization software. A Raspberry Pi is used in the data gateway stage, including a PM2 free open-source process manager to increase the robustness and reliability of the monitoring system. To address this study, data acquisition is performed using commercial hardware solutions that communicate using a Modbus-RTU protocol over an RS485 bus and open software. The experimental facility used to test the monitoring system includes a 2.4 kW pk photovoltaic field, a 3.6 kVA hybrid inverter, a 3.3 kWh/3 kW lithium-ion battery, a 2.2 kVA variable speed driver, and a 1.5 kW submersible pump. The purpose of the monitoring system is to provide a useful tool for the operation, management, and development of these facilities. A technical solution for the monitoring and tracking of PV systems is shown in this work, and a novel quasi-real-time monitoring system for a PVWPS with a Li-ion battery is proposed in which open-source Internet of Things (IoT) tools are used. The inclusion of lithium-ion batteries in grid-connected PV systems is growing, and the sharp drop in prices for these batteries will enable their use in applications such as PV water pumping schemes (PVWPS).
