Voltage stability has recently become a challenging issue in many power systems. The distribution systems are reconfigured with a view to reduce the system losses and offer a better voltage profile for the utilities. This paper presents a new fuzzy based reconfiguration algorithm that enhances voltage stability and improves the voltage profile besides minimising losses, without incurring any ad...

The DSTATCOM (Distribution STATic synchronous COMpensator) is being increasingly popular in power system applications. In general, compensation of reactive power in a power distribution network of a power utility and industry plays a major role in reducing distribution loss and maintaining constant distribution voltage. A simple transformation and steady state and transient analysis are achieve...

Power quality is one of the areas that the power sector is worried about. Power quality is the measure of practical system resemblance to ideal system. Voltage quality can be defined as the maintenance of voltage waveform shape close to ideal shape with proper magnitude and frequency. Even a slight change in voltage of the system can cause serious damage to the power system. Sensitive loads can...

In the DG DemoNet Validation project a coordinated voltage controller was developed to actively integrate a high share of renewables into existing distribution systems. The impact of controlling the medium voltage transformer and the reactive power of distributed generation based on the actual voltages of critical nodes on voltage range and number of tap changer operations is analysed. Evaluati...

An intelligent method based on wavelet neural network (WNN) is presented in this study to estimate voltage harmonic distortion waveforms at a non-monitored sensitive load. Voltage harmonics are considered as the main type of waveform distortion in the power quality approach. To detect and analyze voltage harmonics, it is not economical to install power quality monitors (PQMs) at all buses. The ...

Three solutions for novel distribution automation implemented in medium voltage networks were developed as a theoretical study. The distribution automation studied included intelligent local automation arrangements also useable for ringtype networks. The profitability of the new technique was evaluated by comparing the costs of the automation investments to the savings obtained in the economic ...

The main problems of the power quality like voltage sags/swells in low voltage distribution systems and on the transmission side due to sensitive loads, the terminology used for the compensation devices is different. Dynamic Voltage Restorer (DVR) is one of the equipments for voltage disturbance mitigation in power systems. It is installed between the incoming supply and the sensitive loads to ...
