First, the Energy Provider has been analyzed, by taking malicious usage into account. To this end, (1) we proposed integration of new contractual terms into our novel GreenSDA concept, (2) suggested modification of the “Fair” DC scheduling policy as well as (3) introduced two approaches (centralized and distributed) in order to keep track of monitored parameters.
Besides, the collaboration between Energy Provider and Data Centres has been studied. More precisely, we shortly introduced the contractual terms of the proposed novel Green Supply Demand Agreements between Energy Provider and Data Centres for power adaptation collaboration, and then gave couple of new contractual terms necessary. Furthermore, we carried out an in-depth analysis of the reward and penalty schemes. To this regard, in order to show the viability of the proposed reward and penalty schemes, we presented a real scenario created by the testbed found in Passau between partners SWP and Innowerk-IT. Finally, we presented a comparison of All4Green approach with the existing Demand Response (DR) solutions both in Western Europe and United States. Since in Europe all the provided solutions are propriety and OpenADR is the standard DR solution used in United States, the main focus of the analysis was dedicated to comparing the All4Green concept with respect to OpenADR. Hence, we first analyzed the requirements needed to be fulfilled by Demand Response solutions for the case of data centres. Then, we studied the feasibility of OpenADR to be integrated for the use case of data centres, and derived respectively relevant conclusions.
Also, the Data Centres have been analyzed in terms of energy adaptation capabilities. More precisely, UPS and cooling systems models were evaluated and their accuracy was validated. For this purpose, several field tests both for UPS and cooling system were conducted at Innowerk-IT. Based on the obtained results, a set of models were evaluated, where several refinements were proposed in order to further improve the accuracy of the models. It is worth pointing out that, due to the complexity of the data centre infrastructure, deriving a model for cooling system with firm mathematical as well as physical background was a tedious and time consuming process, which is out of the scope of the All4Green project. Consequently, we derived a customized model by taking into account the field test sample results obtained by Innowerk-IT. As a future work, it would be interesting to study all the factors that play a role in devising a model for cooling systems, with easily extractable parameters. We also went one step further and analyzed the standard protocols used to control and monitor both UPS and cooling systems. In order to show viability of All4Green approach, we conducted an analysis showing the risks that might pop up when using both UPS and cooling system as one of the data centre flexible capabilities. Finally, as a pure research interest, we investigated network virtualization where we proposed several algorithms in order to reduce the energy consumption of networks of data centres.
