“…This finding supports the findings of other studies in this field linking energy with irrigated area and water consumption (Diker 2018). The findings confirm that agricultural lands can be irrigated with less energy use when compared to the results of other studies (González et al 2015;García et al 2014;Carrillo-Cobo et al 2010).…”

Energy efficiency is one of the most important areas that humanity is working on in the world. As in all areas of life, energy used in irrigation has become an important research subject for researchers. In studies performed with performance indicators in Turkey, the use of energy indicators is limited. The scarcity of energy resources makes the efficiency of energy used in irrigation networks extremely important. This study evaluated the performance of a pressurised irrigation network in Yozgat province of Turkey, using the indicators. The data obtained were compared with other countries in the Mediterranean region. The results showed that the specific energy value was about three times lower than other countries. However, when the energy consumed per unit irrigated area was examined, it was found that the irrigation network has high consumption of energy. The use of pressurised irrigation systems will be made mandatory in the coming years, as water resources are reducing because of climate change and drought occurring in the world. Thus, the need of energy for irrigation will increase correspondingly. The use of energy indicators in the planning and implementation of irrigation systems will make significant contributions to the performance of irrigation networks in the future.

“…Different strategies have been implemented to reduce the energy consumption and, therefore, the carbon footprint in the process of groundwater abstraction. Some of these measures are the implementation of energy audits to improve the energy efficiency of the pumping systems [10,12,13] and the use of a variable frequency drive (VFD) to optimize the energy consumed per cubic meter abstracted [8].…”

AS-Solar, a Tool for Predictive Maintenance of Solar Groundwater Pumping Systems

Energy for water abstraction limits the viability of some irrigable areas. Increasing efficiency and introducing renewable energy can reduce energy cost. Solar pumping is a widely recognized renewable energy solution. These pumping systems suffer special wear out due to sudden changes and for having working conditions far from the nominal points. Thus, monitoring systems are becoming more frequent for maintenance issues. A new decision support system, named AS-Solar, was developed to perform predictive maintenance. This model permits detecting if the source of the anomaly in the pump performance is the pump, the electrical components (motor, variable frequency drive (VFD) or cables) or the pumping pipe. It demands real-time data from the monitoring system and an accurate simulation model, together with an optimization process that helps in the decision making in predictive maintenance. To validate the developed model, it was applied to a complex case study of a solar pumping system of 40 kWp that abstracts groundwater from nearly 200 m deep. This pumping system has a VFD, two lines of cables up to the pump and aggressive water with slimes, which causes different problems in the pumping system. In this case study, the AS-Solar model shows an acceptable accuracy, with a relative error (RE) of the 2.9% in simulated power and 7.9% in simulated discharge.

“…Currently, the management of water distribution networks (WDNs) is increasingly based on use of models as decision support tools, particularly in performance and energy efficiency implications (Rodriguez-Diaz et al, 2010;Arbat et al, 2013;Cabrera et al, 2014). When different database and mathematical algorithms are combined, these hydraulic models are an useful tool to analyze WDNs, if these models are properly calibrated.…”

The usefulness of models depends on their validation in a calibration process, ensuring that simulated flows and pressure values in any line are really occurring and, therefore, becoming a powerful decision tool for many aspects in the network management (i.e., selection of hydraulic machines in pumped systems, reduction of the installed power in operation, analysis of theoretical energy recovery). A new proposed method to assign consumptions patterns and to determine flows over time in irrigation networks is calibrated in the present research. As novelty, the present paper proposes a robust calibration strategy for flow assignment in lines, based on some key performance indicators (KPIF) coming from traditional hydrological models: Nash-Sutcliffe coefficient (non-dimensional index), root relative square error (error index) and percent bias (tendency index). The proposed strategy for calibration was applied to a real case in Alicante (Spain), with a goodness of fit considered as "very good" in many indicators. KPIF parameters observed present a satisfactory goodness of fit of the series, considering their repeatability. Average Nash-Sutcliffe coefficient value oscillated between 0.30 and 0.63, average percent bias values were below 10% in all the range, and average root relative square error values varied between 0.65 and 0.80.Additional key words: water management; calibration model; Key Performance Indicators.Correspondence should be addressed to P.
