Future active distribution grids (ADGs) will incorporate a plethora of\nDistributed Generators (DGs) and other Distributed Energy Resources (DERs),\nallowing them to provide ancillary services in grid-connected mode and, if\nnecessary, operate in an islanded mode to increase reliability and resilience.\nIn this paper, we investigate the ability of an ADG to provide frequency\ncontrol (FC) in grid-connected mode and ensure reliable islanded operation for\na pre-specified time period. First, we formulate the operation of the grid\nparticipating in European-type FC markets as a centralized multi-period optimal\npower flow problem with a rolling horizon of 24 hours. Then, we include\nconstraints to the grid-connected operational problem to guarantee the ability\nto switch to islanded operation at every time instant. Finally, we explore the\ntechnical and economic feasibility of offering these services on a balanced\nlow-voltage distribution network. The results show that the proposed scheme is\nable to offer and respond to different FC products, while ensuring that there\nis adequate energy capacity at every time step to satisfy critical load in the\nislanded mode.\n
