Abstract
Datacentres are becoming a sizable part of the energy system and are one of the biggest consumers of the energy grid. The so-called “Green Datacentre” is capable of not only consuming but also producing power, thus becoming an important kind of prosumers in the electric grid. Green datacentres consist of a microgrid with a backup uninterrupted power supply and renewable generation, e.g., using photovoltaic panels. As such, datacentres could realistically be important participants in demand/response applications. However, this requires reconsidering their currently rigid control and automation systems and the use of simulation models for online estimation of the control actions impact. This paper presents such a microgrid simulation model modelled after a real edge datacentre. A case study consumption scenario is presented for the purpose of validating the developed microgrid model against data traces collected from the green edge datacentre. Both simulation and real-time validation tests are performed to validate the accuracy of the datacentre model. Then the model is connected to the automation environment to be used for the online impact estimation and virtual commissioning purposes.
Highlights
Datacentres are rapidly becoming a sizable part of the energy consumption of the society due to the increasing expansion of information and communication technologies
The so-called “Green Datacentre” [3] is a new type of datacentre that is being developed with the aim of building a sustainable future by utilizing renewable energy resources to reduce its carbon footprint
The intended contributions of the paper are as follows: 1. A novel model which models the power dynamics of an edge datacentre microgrid consisting of the Information Technology (IT)-load, renewable PVs, Uninterruptable Power Supply (UPS) battery and the grid connection
Summary
Datacentres are rapidly becoming a sizable part of the energy consumption of the society due to the increasing expansion of information and communication technologies. Author et al.: Preparation of Papers for IEEE Open Journal of the IES commercial energy users can be achieved by means of residual heat reuse for district heating, and on shared use of renewable generation and energy reserve facilities Implementation of such interplay requires developing technologies for tighter integration of datacentre control and automation with energy management systems of residential homes and industrial enterprises. Renewable resources currently operate in a “fit and forget” approach, where the renewables are added to the current infrastructure rather than integrated They do not play an active role in the energy distribution process: the existing centralized generation takes part in the controllability of the energy distribution, but the renewables do not.
