Unregulated utilization of renewable generation including residential photovoltaic (PV) systems can have a significant impact on load characteristics in distribution networks. For improving PV generation capabilities, power quality aspects have to be coordinated with present load characteristics. This paper discusses the harmonic content of PV generation and the influence to power quality indic...

Networks of workstations are commonly used alternatives to dedicated parallel machines, however one of their major drawbacks is the limitation on the communication bandwidth. In this paper, we use parallel network based techniques to optimize the available band-width. In real life, the data arrival and service rates are stochastic (dynamic) processes. Predictive filtering is a commonly used tec...

The paper presents voltage stability analysis of radial distribution networks. A new voltage stability index is proposed for identifying the node, which is most sensitive to voltage collapse. Composite load modelling is considered for the purpose of voltage stability analysis. It is also shown that the load ̄ow solution of radial distribution networks is unique. q 2000 Elsevier Science Ltd. All...

Digital Montessori-inspired Manipulatives (MiMs), so far have been used effectively for knowledge transfer in elementary educational settings. For work modelling and task-based interactive systems design we propose a modelling concept and usage scenario that should help to increase effectiveness in organization and technology development. The Tangible Task Modelling Demonstrator (TTMD) facilita...

This paper deals with the design of a hydraulicmechanical load-sensing system using computer modelling and simulation in an object-oriented programming environment. As initial, the scheme of a hydraulic-mechanical load-sensing system of Bosch GMbH has been taken. A modified scheme of the system is proposed. The object-oriented mathematical model of the system is composed. The approach is based ...
