The widespread use of Power Electronics based equipment has produced a significant impact on quality of electric power supply. Conventional power quality mitigation equipment is providing to be inadequate for an increasing number of applications. One modern and very promising solution that deals with both load current and supply voltage imperfections is the Unified Power Quality Conditioner (UP...

An interactive intuitive graphical simulation package for the analysis of electric distribution systems is presented. It incorporates interactive graphical design of the electric network with a relational data base. The interaction is facilitated with the use of GUI (Graphical User Interface). Two analysis algorithms are integrated allowing the study of load flow conditions as well as the optim...

Abstract: The rollout of electric vehicles substantially changes the requirements for current power grid infrastructures. The high power demand of fast recharge stations in combination with a high risk of simultaneity leads to the necessity of extended ICT integration into the energy distribution process. This paper describes ongoing research on a simulation framework for modeling the communica...

Battery Energy Storage Systems (BESS) can nowadays be used for many applications on the electric distribution grids.

Power distribution system in the country is characterized by high power losses, poor reliability of supply, frequent equipment burnouts etc. The traditional approach in electric power generation is to have centralized plants distributing electricity through an extensive transmission & distribution network. Distribution generation (dg) provides electric power at a site closer to the customer, el...

This paper presents a study to estimate the composition of an electric load, i.e. to determine the amount of each load class by the direct measurements of the total electric current waveform from instrument reading. Kalman filter algorithm is applied to estimate the electric load composition on a consumer side of a distributed power system. The electric load supplied from the different voltage ...
