Network-Constrained Grid-Edge Flexibility Quantification

Grid-edge flexibility enables power systems to adjust generation or/and consumption in response to grid conditions, such as peak demand periods. Quantifying grid-edge flexibility helps system operators to cost-effectively optimize operations and maintain sustainable grids. This paper develops a grid-edge flexibility quantification framework that considers network constraints and evaluates associated cost savings potentials. The analysis allows to incorporate a broad class of loads, generation, and pricing models. The performance of the developed flexibility metric is assessed using an IEEE 33-Bus network and across the Time of Use and Dynamic pricing models. The results show that grid-edge resources can offer flexibility while satisfying the grid's network constraints, a quality essential for sustainable energy transition.
