DREAM: An ICT architecture framework for heterarchical coordination in power systems

Agent based techniques are used to coordinate demand and supply for increasing the embedding capacity of dispersed, badly predictable, renewable energy based power systems. VPPs (Virtual Power Plants) using this technology have demonstrated their feasibility in field tests and currently are scaled up to satisfy requirements for massive rollout ...

Energy management with TRIANA on FPAI

The current growth of smart grid capable appliances motivates the development of general and flexible software systems to support these devices. The FlexiblePower Application Infrastructure (FPAI) is such a system, which classifies devices by their type of flexibility. Subsequently, energy applications only have to support these flexibility...

A structured approach to increase situational awareness in low voltage distribution grids

Wear and tear, electrification and aging of (low voltage) distribution grids require maintenance in order to assure continuous provision of electricity. Situational awareness is required to find out when parts of the grid need maintenance and which parts should be prioritized. The paper proposes a conceptual value model which relates sensor data...

OS4ES: Increasing awareness of DG-RES and demand response processes by registry enabled services

Today, mass presence of distributed energy resources (DERs) connected to the grid is often seen as having adverse effects on grid reliability and robustness. The apprehension is that it complicates or even compromises network management by distribution system operators (DSOs). The central aim of the Open System for Energy Services (OS4ES) [1]...

Uncertainty quantification of aeroacoustic power sources in corrugated pipes

Gas transport in corrugated pipes often exhibit whistling behavior, due to periodic flow-induced pulsations generated in the pipe cavities. These aero-acoustic sources are strongly dependent on the geometrical dimensions and features of the cavities. As a result, uncertainties in the exact shape and geometry play a significant role in...

Reference architecture for interoperability testing of Electric Vehicle charging

This paper presents a reference architecture for interoperability testing of electric vehicles as well as their support equipment with the smart grid and the e-Mobility environment. Pan-European Electric Vehicle (EV)-charging is currently problematic as there are compliance and interoperability issues on different communication levels and among...

Identification of observables for future grids - The framework developed in the ELECTRA project

The main subject of this paper is the classification and identification of observables for present and future grids. In order to make an inventory of present and potentially new observables, a systematic classification and identification of observables for future grids is conducted. After first introducing some fundamental definitions for...

Applying innovative IT modelling methods to low-level grid information for DSO operations

Distribution system operators will gather an increasing amount of electricity data from the lower level of the grid to be able to cope with several challenges, such as an increase of distributed, heterogeneous energy production, local storage, and electric vehicles. Most DSOs are not yet prepared for collecting, storing and processing these...

Privacy enhanced personal services for smart grids

Millions of people are now increasingly using smart devices at home to improve the quality of their lives. Unfortunately, the smart devices that we use at home for comfort and sim-plicity make our lives more complicated in terms of man-agement due to several issues like mismatching interfaces and complexity of the micro-management. One approach...

A topological investigation of phase transitions of cascading failures in power grids

Cascading failures are one of the main reasons for blackouts in electric power transmission grids. The economic cost of such failures is in the order of tens of billion dollars annually. The loading level of power system is a key aspect to determine the amount of the damage caused by cascading failures. Existing studies show that the blackout...

Improving robustness of complex networks via the effective graph resistance

Intelligent energy management using powermatcher: Recent results from field deployments and simulation studies

Response of demand, distributed generation and electricity storage (e.g. vehicle to grid) will be crucial for power systems management in the future smart electricity grid. In this paper, we describe recent results using PowerMatcher a smart grid technology that integrates demand and supply flexibility in the operation of the electricity system...

An inductive power transfer through metal object

The principle of Inductive Power Transfer (IPT)is very old but it is rarely used for transferring power from source to load via a conductive medium. This is because normally the medium restricts the power transfer due to losses or the shielding effects. However, for low energy applications, an acceptable amount of power could be transferred from...

Time-frequency methods for trend removal in electrochemical noise data

Electrochemical current and potential noise signals in many cases exhibit a DC drift that should be removed prior to further data analysis. The theoretical ability of wavelet analysis and empirical mode decomposition to effectively remove only the DC drift component is evaluated based on their mutual performance for the first time. The...

Joint impact of quantization and clipping on single- and multi-carrier block transmission systems

This work investigates the joint impact of quantization and clipping, caused by analog-to-digital converters (ADCs) with low bit resolutions, on single- and multi-carrier block transmission systems in wireless multipath environments. We consider single carrier block transmission with frequency domain equalization (SC-FDE) and the multi-carrier...

Evaluating the speech output component of a smart-home system

This paper describes four experiments which have been carried out to evaluate the speech output component of the INSPIRE spoken dialogue system, providing speech control for di.erent devices located in a ‘‘smart’’ home environment. The aim is to quantify the impact of different factors on the quality of the system, when addressed either in the...
