On the role of pre-curtailed residential PV for primary frequency response considering distribution network constraints

Abstract

The increasing penetration of residential photovoltaic (PV) systems is displacing synchronous generation, causing serious impacts on the provision of primary frequency response (PFR). However, residential PV systems could also be part of the solution by being pre-curtailed to help with PFR. This requires considering not only the changes on system-level dispatch and PFR requirements, but also distribution network constraints to avoid overestimating PV availability. In this work, the distribution network is first analyzed to estimate feasible volumes of PV generation. The results then inform the system-level simulation, where a unit commitment determines the level of pre-curtailment needed for..
