This study considers a distribution system with a number of dispersed generation (DG) units interconnected to the AC grid through power electronic interfaces. Some selected DG units were able to provide energy service and system ancillary services (in particular, voltage regulation and partial compensation or elimination of some power quality disturbances, such as waveform distortions and voltage...
In this paper, the problem of the use of dispersed generation (DG) for providing ancillary services in electrical distribution systems is addressed. Fuel cell-based, photovoltaic cell-based, and wind generation systems are connected to the distribution network through power electronic interfaces, each with a proper storage system for the optimal grid operation. Thanks also to the storage system, the...
The paper deals with the reactive power control in a MV distribution system in presence of Dispersed Generation (DG). The control variables are the reactive powers of DG units and capacitors, and the tap position of the on-load tap changer of the HV/MV transformer. Single-objective and multi-objective optimization problems are formulated and solved in order to achieve the optimal control, even containing...
