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.
Scope of the project is to develop a measurement-based software tool for the modelling and simulation of smart neighbourhoods. The developed measurement-based tool will allow the joint performance assessment of smart neighbourhoods and smart homes (SHs). SHs simulation models will be incorporated and operate at the level of neighbourhood. SHs will be developed by using time-series measurements. For this purpose, already available measurements as well as new data, obtained from the Joint Research Center (JRC) Smart Grids Interoperability Laboratory – Petten, NL will be used. In order to obtain measurement data for the SH model a series of experiments will be carried out. The smart neighbourhood tool will be used to investigate smart grid strategies and technologies in order to improve the performance of the network operation in terms of reliability, security, and optimization. Benchmark distribution grids as well as neighbourhood network models will be incorporated for the simulation of the smart neighbourhood. The simulation tool will be based on the already available open source software package OpenDSS and will be guided by Python.
The Balkan Med (BM) region is facing the challenge of sustaining and increasing the growth of PV systems that is endangered by several barriers and their unpredictable nature. This is especially important in the built environment as member states are developing plans to increase the number of Nearly Zero Energy Buildings (NZEB), which most probably employ PV’s , in order to reach their 2030 climate change targets. As the number of NZEBs increase, PV integration in the distribution grids of BM region will be very difficult, unless buildings become more grid-friendly and policies/regulations are suitably adapted In the above context, the overall objective of project is to enhance the penetration of PV’s in built environment. This will be achieved by using storage, which will transform the building into a more predictable power source. With the high solar potential of the BM region and the decreasing cost of PV/storage systems, such a solution is becoming cost-efficient as well Project aims to change the way buildings with PV’s are treated (i.e. selling energy to grid) and instead conceptualize them as systems that must efficiently interact with grids. Also, it aims to alleviate the above barriers and pave the way for unobstructive NZEB development Main outputs are 1) an innovative management scheme of PV+storage hybrid, making buildings grid-friendlier; 2) a generalized model capable to assess alternative policies related to implementation of such hybrids; 3) An online user-friendly tool able to provide a good first estimate of the profitability of such systems under a specified policy, targeting prospective investors and stakeholders; 4) An advanced tool able to evaluate multiple policy scenarios, targeting policy makers; 5) Set of joint regulation recommendations in the form of roadmap for BM region, targeting grid operators and relevant stakeholders/engineers; 6) Set of joint policy recommendations targeting mainly policy makers and interested stakeholders. The planned approach comprises 1) design the novel management scheme; 2) establish a variety of pilots in each country to maximize impact; 3) widely disseminating results and outputs in the BM region and beyond; 4) bring together key actors to receive feedback and produce targeted outputs to the BM region; 5) follow an open source approach with freely available data & tools to trigger replication.
