![]() As DSOs and TSOs might use the same sources of flexibility, this flexibility should ideally be used in a coordinated way. However, in the future, according to, DSOs will also be expected to procure flexibility to solve issues in their networks. Today, the TSO is the main actor procuring flexibility from flexible units to ensure system stability. ![]() From this perspective, FLEXGRID exploits: (i) topology and monitoring information from the networks that it manages, and (ii) data analytics from the market that it operates in order to provide DESs useful for the design of optimal DER investment strategies and optimal DER portfolio management.īeyond these innovation levels, FLEXGRID copes with a major inefficiency in today’s smart grids, which is the lack of interaction between TSOs and DSOs. To this end, FLEXGRID evolves existing smart grid architectures, which are not able to provide information related to the electricity grid topology and the market conditions to DER investors, by addressing the aforementioned shortcomings. In this context, FLEXGRID develops advanced DESs relevant to the operation of distribution level flexibility markets (DLFMs), aiming to facilitate the efficient management of DNs and the reduction of distribution network management cost.Īnother issue tackled in FLEXGRID is the inefficient investment planning and management of DER assets. Consequently, the DN-related costs remain high (usually driven by DN upgrades with high CAPEX). The development of a dynamic and accurate distribution network (DN) monitoring system and of an efficient and dynamic DN management system is therefore the first step towards mitigating this conservatism.Ī second reason is that even in cases where DSOs dispose distribution management systems with appropriate DN monitoring capabilities, the lack of intelligence that would allow the efficient and dynamic interaction with DER operators (i.e., RES producers, retailers, flexibility aggregators) hinders DER investments. The root cause of this conservatism is the inability of DSOs to dynamically and accurately monitor and manage their networks. The first reason is that DSOs use conservative constraints in distributed DER installation to ensure reliable and secure operation of their network. In this context, the FLEXGRID project is investigating the constraints of the current smart grid architecture that prevent large scale DER integration in distribution networks and consequently mitigates circularity and sustainability in modern smart grids. The large-scale integration of Distributed Energy Resources (DERs), such as PV/wind generation (RES), electric vehicles (EVs), energy storage systems (ESS) and demand side management (DSM) equipment in distribution networks poses new challenges and opportunities for the power sector, as stated in the EU Clean Energy Package. In this context, the FLEXGRID project is developing a digital platform that will offer digital energy services (DESs) that help energy sector stakeholders (i.e., Distribution System Operators (DSOs), Transmission System Operators (TSOs), market operators, Renewable Energy Sources (RES) producers, retailers, flexibility aggregators) to: (i) automate and optimise the planning, operation and management of their systems and assets, and (ii) interact in a dynamic and efficient way with the electricity system and other stakeholders. Circularity and Sustainability in Modern Smart Grids Through Innovative Energy Market Architecturesīy Nikolaos Efthymiopoulos, Prodromos Makris, Emmanouel Varvarigos (National Technical University of Athens)Ĭircularity and sustainability in modern smart grids require open data models that can support dynamic and efficient distribution-network-aware energy management.
