چکیده
The promising increase of Electric Vehicles (EVs) in our society poses a challenging problem on the impact assessment their charging/discharging to power distribution grids. This paper addresses framework nonlinear differential equations. Specifically, we address ODE (Ordinary Differential Equation) model for representing spatial profile voltage phasor along feeder, which has been recently introduced literature. is then formulated as two-point boundary value model. In this derive an asymptotic charcterisation solutions through standard regular perturbation method. provides mathematically-rigor and quantitative method assessing how EVs affects voltage. Effectiveness established with simulations both simple practical configurations grid.

assessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Stochastic Assessment of Voltage Sags in Distribution Networks
This paper compares fault position and Monte Carlo methods as the most common methods in stochastic assessment of voltage sags. To compare their abilities, symmetrical and unsymmetrical faults with different probability distribution of fault positions along the lines are applied in a test system. The voltage sag magnitude in different nodes of test system is calculated. The problem with the...

متن کاملVoltage Profile Optimisation for Weak Distribution Networks
Recent advances in power electronic technology have seen the development of a range of converter based power compensation systems which have the potential to improve supply quality and increase line utilisation in weak distribution networks at relatively low cost. However, the interaction of these devices with the supply network has not been well documented. In this paper we investigate the ste...
