One of the most common applications of energy management is Peak Shaving. In these applications, the power absorbed by the installation is constantly monitored, making it possible to automatically adapt the power consumption to the required levels. The system records the profile of the power absorption on a daily basis and from that data can make forecasts of power peaks that may occur. Based on the forecasts, the system will cut-off specific loads by priority set by the user in order to maintain the peak load under a certain preset level. When the power level decreases, the system will gradually reinstates the loads that were suspended. The main benefit of a peak-shaving system is that peak power levels are maintained within the limits agreed with the power supplier, thus avoiding extra costs and power system overloads.
