The paper proposes a new concept of protection philosophy for Dutch distribution grids with high penetration of renewable energy. Conventional protection concepts are normally based on protection schemes that consist of definite or inverse time overcurrent relays. In future power systems, these schemes can lead to high fault clearing times, unselective tripping and massive DG disconnections, which...
Conventional switches are usually controlled by a manually defined algorithm implemented in the network processor. The conventional methods of control are fast, reliable and transparent. The article deals with alternative method of switch control - based on a neural network, focused on Quality of Service. The article describes the designed model, simulation and summarizes the results.
This paper presents the modeling and simulation work completed in the project sponsored by ONR grant N00014-08-C-0227. The project is to investigate new design concepts of all-electric ship integrated power systems (IPS) and to develop PEBB-based converter models that will represent the existing commercially available products with adequate details and interfaces to allow them to be used in various...
This paper presents a feeder reconfiguration problem to the distribution system with dispatchable distributed generators. The feeder configuration of the system and the dispatch of the distributed generators are two problems that need to be considered. A tabu search algorithm is applied to search for the on/off patterns of the sectionalizing switches and tie switches to obtain the minimum total power...
It is very important for power systems to execute emergency control when large disturbances occur in the systems. Based on the principles of switching control, a new switching model is first formulated for a two-machine power system in this paper. Then, the new model, called switched two-machine power system, is expressed as the form of a switched dissipative Hamiltonian system, and the stability...
In this paper we discuss performance results of a novel real-time closed-loop power amplifier (PA) linearization technique that has originally been proposed by Ahmed and Li. The novel approach performs on-the-fly prediction and measurement of the PA AM/AM and AM/PM non-linearity, stores such non-linear characteristics and calculates their inverse functions in order to pre-distort the base-band amplitude...
