Value of demand flexibility for managing wind energy constraint and curtailment

The dispatch-down of excess wind energy is a growing concern, especially for countries integrating high levels variable renewable energy. Demand flexibility presents an opportunity to move consumers loads periods energy, which could provide numerous values the system. While previous research has focused on managing curtailment (a system-wide issue), much rejected due constraint local issue) and hence can only be resolved by load-on-demand. This paper provides framework assess value demand curtailment. A methodology determine optimal number subscribers yield sufficient reduction in while ensuring reasonable cost savings developed. Analysis shows that this 67% 74% Consumers save up £220 per year, depending their priority dispatch process. 10-MW farm earn £19,400 annually from avoided curtailments. System operators 78% payments. also assesses network impact flexible calculating heat-pump hosting capacity grid.
