“…Battery-based power management: While battery management has been studied in the mobile/embedded domains [15,50,51] (e.g., drain rate adjustment for longevity), their use in datacenters has been limited to mere transition devices during utility failure. Recent work has looked at using UPS batteries to reduce electricity operational costs [20,44], but their role in tighter provisioning for reducing cap-ex is entirely novel.…”

Datacenters spend $10-25 per watt in provisioning their power infrastructure, regardless of the watts actually consumed. Since peak power needs arise rarely, provisioning power infrastructure for them can be expensive. One can, thus, aggressively under-provision infrastructure assuming that simultaneous peak draw across all equipment will happen rarely. The resulting non-zero probability of emergency events where power needs exceed provisioned capacity, however small, mandates graceful reaction mechanisms to cap the power draw instead of leaving it to disruptive circuit breakers/fuses. Existing strategies for power capping use temporal knobs local to a server that throttle the rate of execution (using power modes), and/or spatial knobs that redirect/migrate excess load to regions of the datacenter with more power headroom. We show these mechanisms to have performance degrading ramifications, and propose an entirely orthogonal solution that leverages existing UPS batteries to temporarily augment the utility supply during emergencies. We build an experimental prototype to demonstrate such power capping on a cluster of 8 servers, each with an individual battery, and implement several online heuristics in the context of different datacenter workloads to evaluate their effectiveness in handling power emergencies. We show that: (i) our battery-based solution can handle emergencies of short duration on its own, (ii) supplement existing reaction mechanisms to enhance their efficacy for longer emergencies, and (iii) battery even provide feasible options when other knobs do not suffice.

“…The power grid cyber-physical infrastructure is shown in Figure 9. Meanwhile, a dynamic battery model that supports control systems in CPS to enable the prediction of battery life was discussed in 2009 (Zhang et al, 2009). This is jointly done by an online scheduling algorithm and battery management framework to optimize the performance of the batteries, computing device and the plant as a whole.…”

Due to its vast number of suitable applications, Cyber-Physical Systems (CPS) has been one of the emerging and rapidly-developed technologies in modern life. Its applications can be integrated and deployed in numerous sectors, for instance the automobile, home appliances, medical and industrial sectors. This field has seen immense development and research taking place, including the architecture model, security, communications mode, control systems model and also signal processing. CPS plays an important role in Industrial Revolution 4.0, where it is an integration of urbane network with intelligent production or process system. CPS main objective is to control the global networks with high credibility of data secured. This paper is basically a review of the CPS architectures, characteristics and its applications in daily basis. This review paper discusses how CPS are implemented in various industries and how it improves the efficiency of a system or application. Additionally, security enhancements in certain aspects of CPS application will also be reviewed and addressed.

Towards Energy Efficient Scheduling of Manufacturing Systems through Collaboration between Cyber Physical Production and Energy Systems

Currently, enhancing sustainability, and in particular reducing energy consumption, is a huge challenge for manufacturing enterprises. The vision of the fourth industrial revolution (so-called “industry 4.0”) is not only to optimize production and minimize costs, but also to reduce energy consumption and enhance product life-cycle management. To address this challenge, a multi-agent architecture aimed at elaborating predictive and reactive energy-efficient scheduling through collaboration between cyber physical production and energy systems is proposed in this paper. Smart, sustainable decision tools for cyber physical production systems (CPPS) and cyber physical energy systems (CPES) are proposed. The decision tools are data-driven, agent-based models with dynamic interaction. The main aim of agent behaviours in the cyber part of CPPS is to find a predictive and reactive energy-efficient schedule. The role of agents in CPES is to control the energy consumption of connected factories and switch between the different renewable energy sources. Dynamic mechanisms in CPPS and CPES are proposed to adjust the energy consumption of production systems based on the availability of the renewable energy. The proposed approach was validated on a physically distributed architecture using networked embedded systems and real-time data sharing from connected sensors in each cyber physical systems. A series of instances inspired from the literature were tested to assess the performance of the proposed method. The results prove the efficiency of the proposed approach in adapting the energy consumption of connected factories based on a real-time energy threshold.
