This paper presents two different but very important aspects of distribution network that’s voltage profile and losses. By keeping in view of these parameters this is to be decided where the distributing generating Units must be placed in distribution network. In the present and future Distributed generation (DG) has its vital importance due to more demand of electricity and renewable nature of...

This paper presents a case study that highlights the influences which the connection of distributed generation sources may have over the solutions of reactive power compensation and voltage control already existing in a given network. The problem of voltage-reactive power control to minimize energy losses was solved by changing the number of capacitor banks located in buses and changing the tap...

With the increasing penetration of renewable energy in power systems, fluctuation of renewable energy power plants has great influence on stability of the system, and renewable power curtailment is also becoming more and more serious due to the insufficient consumptive ability of local power grid. In order to maximize the utilization of renewable energy, this paper focuses on the generation sch...

The increasing development of the use of new energies has led to the widespread use of power electronics, so that electronic power converters play an important role in extracting power from renewable sources. Power electronics can convert raw energy produced from new energy into the desired power with controlled current, voltage and frequency to be used in the power grid. Restructuring of power...

Since the late 1970s, intensive efforts have been made to utilise renewable energy sources, such as wind, hydro, solar and tidal. However, the application of individual distributed generators can cause as many problems as it may solve. A better way to realise the emerging potential of distributed generation is to take a system approach that views generation and associated loads as a subsystem o...

as renewable energy increasingly penetrates into power grid systems, new challenges arise for system operators to keep the systems reliable under uncertain circumstances, while ensuring high utilization of renewable energy. this paper presents unit commitment (uc) which takes into account the volatility of wind power generation. the uc problem is solved with the forecasted intermittent wind pow...

Shifting our electricity generation from fossil fuel to renewable energy sources introduces large fluctuations to the power system. Here, we demonstrate how increased fluctuations, reduced damping, and reduced intertia may undermine the dynamical robustness of power grid networks. Focusing on fundamental noise models, we derive analytic insights into which factors limit the dynamic robustness a...

This paper presents a technical review of power quality problems associated with the renewable based distributed generation systems and how custom power devices (CPD) such as STATCOM, DVR and UPQC play an important role in power quality improvement. IEEE and IEC standards for grid connected renewable energy systems are one of the critical points of interest for the selection of custom power dev...

The objective is to develop a system model to simulate distributed power generation in power parks, where power generation is co-located with businesses or industries. The deliverable of the project will be a tool for simulation of the local power generation system, constructed in the Simulink software. We have developed a library of modules for the various components being proposed for power p...
