INGENIEUR Battery room restore a system’s power balance, whereas the flexibility sources respond to restore that balance. While flexible resources are commonly found on the supply side, there is also the possibility of harvesting flexibility from the demand side (Demand Response, DR). Large-scale industrial processes and direct control of certain loads have been utilised for many years. Recent advances in information and communication technologies (ICT), together with the large-scale rollout of advanced smart meters, have created a new window of opportunity to make better use of DR to increase flexibility. The flexibility required can be obtained by scheduling and dispatching certain loads (either individually or as aggregation of smaller loads) according to system needs while respecting a set of preconditions, such as comfort levels. Alternatively, price-responsive demand can be used with price signals that reflect flexibility requirements.
