Aggregator Operation in the Balancing Market Through Network-Constrained Transactive Energy
article
The future renewable-based power system will have
an increased need for balancing power. Prosumers, having both
generation and consumption capabilities, are expected to provide
balancing power to the grid, if their flexibility can be appropriately
managed. Meanwhile, undesirable line congestions and voltage
violations may arise in the distribution network, when flexible
resources respond to external control or price signals on a large
scale. Hence, the development of an effective framework to coordinate
flexibility at the distribution system level is of utmost importance.
Such a framework should allow for an optimal provision
of prosumer balancing power services within the boundaries of
local network security constraints. In this study, a balancing market
participation framework is proposed, adopting the concept of
network-constrained transactive energy, to facilitate the interactions
between the transmission system operator and aggregators
who manage prosumer energy profiles. This framework retains
user privacy and complies with the current market setup, where
flexible energy is traded on the spot and balancing markets; however,
it is ensured that the resulting energy profiles do not cause
problems in the distribution network.
