Power system load forecasting using mobility optimization and multi-task learning in COVID-19 PMC

This cargo loader provides main deck and lower lobe container loading capability for a wide range of aircraft. Compared with smaller loaders the Loadstar 140 saves loading and offloading time and can handle all pallets and containers up to a weight of 14 tons and a length of 20 feet. Meanwhile the Company offers it successful Commander family of loaders. The Commander 15i features the HeliRoll conveyor system and has a lift capacity of 7,000 kgs). It provides main deck and lower lobe container loading capability for a wide variety of passenger and freighter aircraft.

The user communicates with the system through a request, and the response to it should come at an acceptable time. The specific character of high load systems lies in the fact that you cannot work with them like with any other system. As a rule, special attention is required when optimizing high load.

Stress testing.

Most often, it’s the first node which is under load is the database. Each request from the user to the application is generally from 10 to 100 database queries. Database branching on a separate server will increase its performance and reduce the negative impact on other components (PHP, Nginx, etc.). Introducing secure coding practices, reliable user authentication and authorization algorithms and protected communication between your app and third parties is vital. To this end, some businesses choose to deploy AS/RS systems to automate warehousing and streamline product storage and retrieval operations.

The type of scaling you choose should depend on the requirements for your system and the issues you need to solve by scaling. For example, if you run a marketing campaign and many users joined the system as a result, or a new additional feature unexpectedly brought a plenty of users, or you just expand your project. Grow your team and expand your software development capabilities with a reliable tech partner by your side. The Apps Solutions guarantees the production of scalable and high-performance apps in the following ways.

High-load applications and systems are essential in today’s digital economy, where scalability and reliability are vital. In fact, they’re even more important now, with whole business domains moving online because of the pandemic. The rise of user activity and data volumes puts exacting demands on software development processes, and businesses find their high-load applications put to the test. When developing high-load applications, load testing plays an important role. Since it doesn’t make sense to immediately adapt applications to hundreds of thousands and millions of users, it is very important to understand when the time comes to scale.

Load distribution.

Almost all traditional and even optimized load forecasting models seem powerless [6] when facing such public emergencies and crises. High load is a system with many users and a real audience growing with time. Whether there are ten users in an hour or millions of users at once, the supporting infrastructure can expand to fulfill demand. Quintagroup developers may create and execute apps using the serverless architecture, a cloud-native development methodology. If you’re running a new application, it makes no sense to immediately provide an infrastructure that can handle millions of users and process millions of events a day.

High-Load System Main Features

Methods of engaging customers in demand response efforts include price-based programs such as real-time pricing (RTP), time-of-use (TOU) pricing and critical-peak pricing (CPP) [573]. The price-based DR programs give customers time-varying rates that reflect the value and cost of energy in different time periods. It also includes incentive-based programs that give incentive payments to customers in exchange for reducing their energy use at time of peak demand.

For this given structure, the ratios of the stages have to be determined. A variation of microgeometries is analyzed by an analytical method and an interactive selection allows the identification of a desired result. The modifications are designed to also account for the influence of manufacturing deviations. For increasing normal module, high load system architecture that influence gets less significant, since other parameters (clearances, deformations) amount to most of the resulting deviations in contact. Objective function and constraints of microgrid (MG) energy management. Possible HVAC control methods are reviewed in Afram and Janabi-Sharifi [32] and schematically reported in Fig.

  • Upon successful completion of the first phase, the project will be eligible for follow-on grants to develop, demonstrate and commercialise the product.
  • The first dimension is the trigger criteria illustrating how and when the participants are called to shed load.
  • To compensate for manufacturing deviations, varying loads and other uncertainties, a microgeometry with a certain amount of crowning or end relief hast to be designed.
  • A project that comes with scalable architecture from the Minimal Viable Product (MVP) stage is likely to be more profitable and provide a better user experience.
  • There is no significant difference in training time between locations for single-task learning.

Hundreds of interconnected settings can both “help” the system and spoil its work. The job of a specialist is to choose the right parameters so that business tasks are performed successfully, and for this, you often have to study new materials, use previous experience, conduct many tests, and so on. But in reality you will first need a server for 0.5 million, then a more powerful one for 3 million, after that for 30 million, and the system still will not cope. And even if you agree to pay further, sooner or later there will be no technical way to solve the problem. If we draw an analogy with an ordinary clothing store, then instead of servers, programming languages ​​and IT stuff like that, there is a simple and understandable consultant, cash register and goods. On a typical day, a consultant approaches each client, helps to choose the size, advises accessories, then escorts to the checkout and calculates the buyer.

One of the biggest differences between single-task learning and multi-task learning is the length of calculation time. Table 6
shows the training time of each region using new mobility optimized data. It can be seen that the calculation time of each region is very close, ranging from 96 s to 100 s. There is no significant difference in training time between locations for single-task learning. Table 7
shows the impact of different numbers of parallel load forecasting tasks on training time and speed-up. When the number of parallel tasks is small, the speed-up effect of multi-task learning is not obvious, with a speed-up rate of 14.84%.

Or you will decide to promote your application and attract customers. Therefore, you must be able to elastically scale and handle high loads. Choosing the right architecture for your web product is a crucial issue that you need to solve when thinking through its development. First and foremost, it should be scalable and be able to handle high loads. Especially if you’re making a functional website, online booking service, or an e-commerce solution. Most experts agree that when designing a high-load app, non-functional requirements take priority over functional ones.

Readers can arbitrarily set the task of the region they are concerned with as the target task. In recent years, transfer learning and multi-task learning have been applied in load forecasting and have achieved extremely impressive results. Unlike the normal machine learning process, the transfer learning process pays attention to the proper time to switch to transfer learning [33]. Also, it is significant on selecting data features for knowledge transfer [34]. Including features that have a low correlation with load into the load forecasting process can reduce the accuracy of load forecasting. Study [35] first established a joint forecasting model of electric, heating, cooling, and air loads based on multi-task learning and least-squares vector machines.
