Evaluation of PV curtailment option to optimize PV integration in distribution network

摘要

Due to present regulatory framework, connection studies and scheme for generators (PV, Wind…) are designed to guaranty that all capacity can be injected in the feeder any time of the year in normal operation. Any injection above the connection capacity of the contract is forbidden. This can result in grid adaptations (reinforcements or heavier structural modifications) triggered by short duration constraints. It is thus rational to look for alternative solutions with better costs. Among those active curtailments (reduction of active power injection during short periods) appears to have interesting features and possible drawbacks: we develop this idea further in this paper for MV PV generation.
