The design of a power buffer to mitigate the negative impact of constant power loads on voltage stability as well as enhancing ride-through capability for the loads during upstream voltage disturbances is examined. The power buffer adjusts its front-end converter control so that the buffer-load combination would appear as a constant impedance load to the upstream supply system when depressed vo...

This paper describes the mathematical modelling of selfexcited induction generators (SEIGs) with are improved electronic load controller (IELC) for microhydel applications supplying variety of loads. In small hydro plants, governor unit of turbine can be eliminated using IELC, which is simple and cost effective. The improved electronic load controller is a combination of a three-phase insulated...

Abstract: Reducing voltage to reduce energy consumption, referred to as conservation voltage reduction (CVR), can lead to energy savings. Calculating the effects of reducing voltage requires accurate load models. This paper investigates a load-voltage dependency factor that can be measured via field experiments using common existing instrumentation. A relationship between the load-voltage depen...

The presence of renewable energy sources in hybrid systems is considered a significant challenge since the generation mainly depends on meteorological conditions. Hence, employing robust and flexible storage system is, therefore, crucial solution such circumstances. This paper investigates performance evaluation both batteries superconducting magnetic (SMES) integrated with solar-wind DC-bus mi...

Euler-Lagrange coupling method is used to establish the fluid-structure interaction model for tires with different tread patterns by obtaining grounding mark and normal contact force between tire road surface during rolling. The altering of load force, pressure, water film thickness in relation effect on tire-road both constant speed critical hydroplaning was analyzed. Results show that are pos...

This work deals with the transient hydroelastic analysis of a sandwich beam which represents a boat hull. The beam is subjected to slamming pressure while it enters into water with constant vertically downward velocity. A coupled hydroelastic finite element model is developed using higher order shear and normal deformation theories for the faces and the core of the beam and the velocity potenti...
