24 results about "Load profile" patented technology

In electrical engineering, a load profile is a graph of the variation in the electrical load versus time. A load profile will vary according to customer type (typical examples include residential, commercial and industrial), temperature and holiday seasons. Power producers use this information to plan how much electricity they will need to make available at any given time. Teletraffic engineering uses a similar load curve.

Garbage data dynamic recycling method, device and equipment and computer readable medium

PendingCN122363964ADistributed objectCluster based
This application relates to a method, apparatus, device, and computer-readable medium for dynamic garbage data recycling. The method includes: collecting operating parameters of a distributed object storage cluster and submitting these parameters to an analysis cluster; constructing dynamic load profiles of multiple storage buckets in the distributed object storage cluster based on the operating parameters in the analysis cluster; generating corresponding dynamic recycling strategies for each storage bucket according to its dynamic load profile; and recycling garbage data from each storage bucket according to the dynamic recycling strategies. This application constructs dynamic load profiles of storage buckets based on the collected operating parameters, achieving real-time perception and accurate characterization of the cluster's load status. This allows for the generation of targeted dynamic recycling strategies adapted to the load characteristics of each storage bucket, replacing the traditional static threshold triggering mechanism. This avoids resource contention during peak business periods and solves the technical problem that the static threshold triggering mechanism for garbage data recycling cannot adapt to dynamic load changes, leading to system performance degradation.

METHOD FOR OPERATING AN ELECTRICAL POWER SYSTEM IN A BUILDING

A procedure for operating an electrical energy system in a building includes a step for collecting a variety of consumption data on the electrical active energy drawn. This active energy is drawn from the public electricity grid and / or from existing energy generators within the building's energy system via a grid connection point. A load profile is determined based on the consumption data. This load profile describes the expected or historical trend of the active energy drawn over a given period. A backup generator for generating and / or supplying electrical energy is then selected based on the load profile. The backup generator is intended to operate instead of, or in addition to, existing energy generators within the building's energy system and / or to reduce the amount of active energy drawn from the public grid.

Automatic Management System and Method for Ship Power Plants Based on Load Forecasting

This invention relates to the field of automatic management technology for ship power plants, specifically to an automatic management system and method for ship power plants based on load prediction. The system includes a load prediction module that receives multi-source data acquired by a data acquisition and fusion module and outputs a predicted load curve for the ship using a pre-trained load prediction model. An optimization decision module dynamically calculates the ship's safety margin based on the predicted load curve obtained by the load prediction module and dynamically generates start-up, shutdown, paralleling, and disconnection control commands for the ship's generator sets. By predicting the future load curve of the ship, this invention can start standby generator sets in advance before the predicted overload risk point, ensuring that paralleling and load transfer are completed before the peak load arrives. This effectively avoids the risk of overload tripping due to generator start-up delays and greatly enhances the robustness of the ship power plant.
