    GReSBAS project: A gamified approach to promote more energy efficient behaviours in buildings
    ( 2017) António Cunha Barbosa ; Filipe Joel Soares ; Ozdemir,A ; Zehir,MA ; André Guimarães Madureira ; Kucuk,U ; Portela,J ; António Coelho ; Fernando Cassola Marques ; José Pedro Iria ; 5929 ; 4560 ; 4999 ; 5090 ; 5485 ; 3132
    The GReSBAS project (2016-2019) aims to enable the active participation of buildings in DR programs through gamified competition between building owners. In case of large buildings, gamified competition can be established within the building for its occupants, for instance having different floors of the building competing between them. This approach will allow building owners to reduce electricity costs and increase energy efficiency by motivating/rewarding building occupants for participating in DR programs. The concepts and tools developed under GReSBAS will be tested in two demonstration sites: a corporate building in Portugal and a residential building in Turkey. This paper presents the Portuguese demonstration site and describes how the energy consumption, temperature and building occupancy data will be collected, processed and used by the tools developed in GReSBAS.

    Identification and comparison of power and energy management capabilities of distributed energy resources
    ( 2018) Sandroni,C ; Verga,M ; Lazzari,R ; Zehir,MA ; Barbosa,A ; Pellegrino,L ; Ozdemir,A ; Filipe Joel Soares ; Kucuk,U ; Bagriyanik,M ; 4999
    Distributed energy resources (DERs) can provide a number of functions to be used in grid services with proper establishment of control and communication systems. However, there are neither general standards for vendor independent integration of these assets in management activities, nor common consideration of specific flexibilities that different DERs have. This paper investigates characterization and comparison of individual power and energy management flexibilities of different types of distributed energy resources. Emerging DER capability identification approaches are used to highlight contrasting differences between several energy storage and distributed generation options. Experiments were conducted in a low voltage test facility to compare flexibility limits using the same control and communication infrastructure. © 2018 IEEE.

    Management of Inverter-based Distributed Energy Resources for Providing Voltage Regulation Support in Islanded Operation of Low Voltage Networks
    ( 2018) Verga,M ; Bargiyanik,M ; Ozdemir,A ; Barbosa,A ; Filipe Joel Soares ; Sandroni,C ; Pellegrino,L ; Lazzari,R ; Kucuk,U ; Zehir,MA ; 4999
    Growing number of inverter-based distributed energy resources (DERs) and sensitive loads increase the need for coordinated power management activities in islanded operation of microgrids. Especially low voltage networks have low inertia and high R/X ratio, causing instability due to fluctuations in distributed generation (DG) and local voltage problems in islanded operation. This study investigates management of DERs that operate in current mode for providing voltage regulation support to master unit(s) in islanded operation of microgrids. A special focus was set on local voltage issues in low voltage (LV) network feeders. Field experiments in a large test facility highlighted management accuracy and corrective impact potential of DERs connected to different parts of a feeder. © 2018 IEEE.

    Vertical Load Uncertainty at the T/D Boundary under different spatial der allocation techniques
    ( 2019) João Vieira Silva ; Miranda,V ; Melo,J ; Duenas,P ; Filipe Joel Soares ; Heymann,F ; Vilaca,P ; 6299 ; 4999
    Vertical load is the power flow between electrical transmission and distribution networks. In the past, large-scale generators connected to transmission systems supplied consumers connected to lower voltage levels across distribution grids. Thus, vertical loads tended to be downward-oriented. This paper presents a spatiotemporal distributed energy resources (DER) diffusion model to analyze vertical load uncertainty resulting from different DER diffusion process representations currently used in the industry and academia. Network planners and operators can use such model to understand the long-term evolution of load at the T/D boundary. The proposal is applied to the Portuguese power system, combining, as first of its kind, highly granulated population census with georeferenced transmission and distribution network datasets. This application analyzes the 20-year evolution of such vertical load flows at the transmission-distribution boundary under a strong uptake of DER embodied in lower voltage levels in Portugal. © 2019 IEEE.
