Abstract
To prevent black-outs due to over-consumption, electrical power systems usually rely on under-frequency load shedding (UFLS). In France, it is implemented by disconnecting pre-selected MV feeders from the distribution system. The feeders taking part in the UFLS scheme are chosen according to a specific objective in terms of total amount of power to be shed. Various ways to define and calculate this objective may be considered. This is particularly true when a significant distributed generation (DG) capacity is present and must be considered in the UFLS scheme. This article studies how the choice of the definition, and means of calculation, of the objective impacts UFLS performance – the production from the DG may be such that the local objective to shed becomes negative. This analysis is based on the real consumption data of all MV feeders from six French regions, provided by the main French DSO, Enedis.
