Local controllers are essential in distribution networks; they are employed in classical devices such as load tap-changing (LTC) transformers and switchable shunt capacitors, and more recently in distributed generation (DG). The effective use of distribution management system (DMS) applications requires an accurate model of the interaction between the local controllers through the distribution system...
Distributed Generators (DG) are generally modeled as PQ or PV buses in power flow studies. But in order to integrate DG units into the distribution systems and control the reactive power injection it is necessary to know the operation mode and the type of connection to the system. This paper presents a single-phase and a three-phase mathematical model to integrate DG in power flow calculations in...
Flexible AC transmission systems (FACTS) is an evolving technology, which can be used to improve power system utilisation. Determining the type, location, device number, and device compensation are critical to successfully utilizing FACTS controllers, and this paper presents a method of Unified Power Flow Controller (UPFC) placement, which is capable of simultaneously determining number of UPFCs,...
