We propose a methodology for proactive maintenance of Uninterruptible Power Supply (UPS) devices based on online health-status monitoring and application of data analytics for prediction of UPS components' failures. The goals of the work are (i) improvement of reliability of UPS devices by ensuring prompt action prior to a failure of a component, and (ii) provision of more cost-effective maintenance...
With growing complexity of electric power systems, a total number of disturbances is expected to increase. Analyzing these disturbances and understanding grid’s behavior, when under a disturbance, is a prerequisite for designing methods for boosting grid’s stability. The main obstacle to the analysis is a lack of relevant data that are publicly available. In this paper, we present a design and implementation...
A gradual move in the electric power industry towards Smart Grids brings several challenges to the system operation such as preserving its resilience and ensuring security. As the system complexity grows and a number of failures increases, the need for grid management paradigm shift from reactive to proactive is apparent and can be realized by employing advanced monitoring instruments, data analytics...
With Smart Grids efficiency of the electric power delivery service can be significantly increased by using advanced ICT infrastructure. The looming danger of merging two critical infrastructures, ICT and electric power, is that dependability may be compromised due to interdependencies and different approaches to dependability in the two communities. This calls for a unified approach to dependability...
Energy consumption can be to some extent steered not only in time but in special cases in space as well. This mostly concerns electric vehicles (EV) charging. In this work we present conceptual solution of a ‘GeoGreen Cell’ developed in scope of an international project — Ge(o)Green. The main purpose of such an aggregation is to efficiently coordinate. EV charging with respect to price of energy both...
Massive deployment of distributed energy resources, predominately renewable, is expected to be a general trend in the near future. Integration of such elements in distribution grid represents one of key challenges that Smart Grids will have to face with. In this work we aim at bridging industrial and academic views on future trends in this field. We list main issues to be tackled and we propose a...
Technically sustainable solutions for integration of (PH)EVs in Smart Grid emerge as an important concern. We discuss the need for introduction of Virtual Aggregations supported by implementation of Virtual Meters in power system structures. We advocate our proposal with an evaluation of scenarios based on realistic data. The structure and functionalities of the Virtual Aggregator, as well as proposed...
Economical and environmental concerns push toward novel solutions for sustainable, renewable and intelligent energy power grid — the Smart Grid. Such complex system, or better aggregation of systems, involve a number of various stakeholders coming from different areas of expertise, requires novel ICT solutions, etc. Even so, on-going projects do not apply unique formal design methodology and language...
Modern power systems, in particular Control Center structures, involve more and more software applications in their normal operation. Such scenario urges for standardization of inter and intra processes communication and data exchange. In this work we propose a solution for seamless Meter Data Management (MDM) integration with Control Center structures through Common Information Model (CIM). The solution...
Reconfigurable technologies are getting popular as an instrument not only for verification and prototyping but also for commercial implementation of Multi-Processor System-on-Chip (MPSoC) architectures. These systems, in particular Network-on-Chip (NoC) based ones, have emerged as a design strategy to cope with increased requirements and complexity of modern applications. However, the increasing heterogeneity,...
This paper presents a novel architecture for Smart Metering systems which enables their seamless, secure and efficient integration in wider SmartGrid software structures. Smart metering solutions represent one of the fastest evolving areas in the field of power distribution systems. There is an extensive interest of leading software vendors in the field, for development of architectures that can efficiently...
Security is gaining increasing relevance in the development of embedded devices. Towards a secure system at each level of design, this paper addresses the security aspects related to Network-on-Chip (NoC) architectures, foreseen as the communication infrastructure of next-generation embedded devices. In the context of NoC-based Multiprocessor systems, we focus on the topic, not thoroughly faced yet,...
