Conference Paper
This paper presents the development of a smart bin application, aiming at the upgrade of conventional, already in use bins, transforming them into a vital component of the smart city concept. Special attention has been paid in the cost effectiveness of the proposed solution, in order to become sustainable. In this context, the use of a popular and...
Conference Paper
This paper proposes the incorporation of SmartPV technology (i.e., smart photovoltaic cell-level integrated inverters) in Zero Energy Building (ZEB) concept, in the context of the strict EU guidelines regarding the transformation of the existing high energy consuming buildings into ZEBs, until 2030. ZEBs feature reduced energy demands, since most o...
Article
Originally, ancillary services (ASs) were provided by large-scale power plants to ensure the secure and reliable operation of power systems. However, with the advent of renewable energy sources either in large-scale or as smaller distributed generation units, there is a strong need to revisit the structure and aim of traditional ASs and reconsider...

In the coming years, distribution grids will be progressively flooded by renewable energy sources (RES) that will be interconnected with the main grid through power electronic converters. Photovoltaics (PVs) are one of the most promising renewable technologies even for densely built‐up areas where space problems are inevitable. The high penetration...
Conference Paper

This paper presents the analysis and design procedure of a low voltage, reconfigurable, on-chip DC/DC - DC/AC power conversion system for PV applications.The whole work is carried out in the context of a novel smart PV system development, which is based on integrated PV cell inverters. Various power converter topologies are investigated in order th...
Conference Paper
Full-text available
This study presents a control scheme for thermoelectric coolers (TECs), based on the implementation of a double PI control loop for supply current and ventilation regulation. A test bench was developed, including a thermal closet and all the necessary automation for data acquisition. Industrial thermocouples were employed in order to record the hea...

To increase the reliability of aerospace electronics and reduce their overall power consumption, we investigated the possibility of incorporating active thermo-electric cooling (TEC) solutions. The harsh avionic environment demands sophisticated active control schemes that enable the achievement of high coefficient of performance (COP). The positiv...

Title: Experimental investigation on the performance characteristics of anti-islanding techniques in the prospect of high PV penetration level
Project
This research project is proposed to develop a system of Smart Solar Cells, comprising the conventional Solar Cells that are connected to an integrated circuit (IC). which will be designed and constructed within the framework of the proposed project. This IC will be responsible for the maximization and management of the energy produced by the solar cell, the detection of malfunctions and for the remote (through Internet) control and monitoring of the Smart Solar Cell operation. The IC will be designed such that it can be used in combination with solar cells of any manufacturing technology (e.g. multi-crystalline, thin-film etc.). The proposed project targets to design, construct and experimentally evaluate a fully-functional prototype PV system of Smart Solar Cells. The proposed Smart Solar Cell will ensure the continuous production of the maximum possible power by the PV system (thus minimizing the cost per unit energy produced by the PV systems), the optimal exploitation of the available installation surfaces, the reduction of the installation and maintenance costs of the PV systems and the reduction of the PV panels manufacturing costs, since the matching process of the individual solar cells incorporated in the same panel will not be required during their manufacturing process. Due to the innovative character of the proposed system at both the research and industrial levels, activities for exploiting the project results will be implemented, targeting to the optimal exploitation of the commercial potential of the proposed system.
Project
The main objective of ACTIVATE project is to develop novel DSO-oriented and TSO-oriented ancillary service solutions. These solutions aim to address the emerging grid operation challenges caused by the increased DG penetration and especially by the intermittent nature of DRESs. The ancillary services to be developed will be based on exploiting the functionalities the network assets offer including: (a) ESSs, (b) novel operational features of the grid-interfaced converters of ESSs and DRES units, which will be developed within this project, and (c) a new monitoring system architecture for active distribution networks (ADNs) based on measurements acquired locally at the point of common coupling (PCC) of the DRES units. This project will contribute to the increase of supply reliability and RES penetration, in an attempt to meet the targets European Union has set to improve sustainability, flexibility, and efficiency in the electricity sector.
