Flexibility and demand: a distribution systems operator’s perspective - Joost Gottmer, EU affairs, EDSO for Smart Grids could provide services to the DSOs either under the umbrella of an aggregator or individually. SMEs with a fleet of electric vehicles or who use electricity for thermal control would be of particular interest due to thermal inertia. Household customers who are directly connected to distribution grids, could be an important source of flexibility for network operators. Whereas individual household provision of flexibility is likely to have a low impact on grid management, household customers could potentially contribute to a pool of flexibility through their supplier or aggregator. An aggregated fleet of electric vehicles, heat pumps or air-conditioning are examples of devices that could provide flexibility. Customers’ participation in demand-side flexibility can depend on a number of factors: technology availability, willingness to change behaviour or individual preferences. To engage customers successfully, however, flexibility operators should offer clear price signals, access to information as well as innovative tools and services that are easy to use. Customers who wish to earn from their flexibility should also be able to freely choose between all products available. CONCLUSION Flexibility can be a more-cost effective and socially-accepted alternative to conventional grid reinforcement that will help DSOs’ networks to integrate variable RES and distributed loads. DSOs could make the most of their grid provided that they are allowed to use system flexibility services. In a similar fashion, increasing flexibility in the electricity market (when technically and economically appropriate) would result in a number of benefits for DSOs, consumers (all grid users) and society as a whole. This, however, implies that distribution networks are planned differently, incorporating new risk margins and uncertainty, are not only managed as they used to be, but rather as networks with enhanced observability, controllability and interactions with market stakeholders.
