Abstract

The control scheme is key for providing a stable and reliable grid operation under best economical conditions primarily in rural microgrids. The aim of this study was to investigate the use of a blackstart control scheme considering small production processes and its potential benefits for the whole system. A microgrid (MG) model based on the practical features of an actual MG called Huatacondo, which is located in the north of Chile has been developed to asses the control scheme capabilities. The results show that using the blackstart control scheme combined with the knowledge of the load behavior of the processes, it is feasible to maintain the system within its normal operating conditions. This indicates that when a failure in the system occurs, the control scheme is capable of recovering the whole system avoiding a severe decline in the frequency. Thus, the system can be operated in a cost-efficient way.
