This paper proposes a necessary condition for power flow insolvability in power distribution systems with distributed generators (DGs). We show that the proposed necessary condition indicates the impending singularity of the Jacobian matrix and the onset of voltage instability. We consider different operation modes of DG inverters, e.g., constant-power and constant-current operations, in the proposed...
Summary form only given. The positive feedback-based anti-islanding scheme has become a common anti-islanding protection technique for inverter-based distributed generators (DGs). This paper investigates the scheme's impact on the small-signal stability of multiple inverter-based DGs installed in power distribution systems during grid-connected operation. The interactions among multiple-DGs due to...
The fault location in electrical power systems has been considered as a issue, specially as a consequence of the regulatory requirements related to power quality. In this paper, a statistical classification algorithm based on fuzzy probability functions used to locate single phase faults in distribution systems is presented.
A new method for reliability assessment and performance based incentives of power distribution systems is presented. The reliability estimation is based on a Monte-Carlo simulation of the system average interruption duration index (SAIDI). The normal distribution resulting from the simulation is used as a base for a performance based incentives scheme. In order to create an applicable model for supervisory...
