In this work, a reactive power-voltage (QV)-based framework to evaluate the voltage instability sensitivities of power system buses to increase in renewable energy (RE) penetration has been developed using two sensitivity ...

This paper is about the design and development of a microcontroller based solar tracking system. Solar energy is rapidly becoming an alternative means of electrical source in Kenya and all over the world and the solar ...

Voltage Source Converter-High Voltage Direct Current (VSC-HVDC) is the most efficient and reliable method for electrical power transmission over long distances. The greatest challenge with VSC-HVDC system is that short-circuit ...

The Voltage Source Converters, High Voltage Direct Current (VSC-HVDC) system is the most preferred alternative technology for transmission and distribution of electrical power due to its intrinsic distinctiveness in ...

The current power grid is in the verge of being improved. Recent technological advances have made possible the creation of a new and improved grid known as the smart grid. Smart grid allows for better interaction between ...

In the past decade, electricity demand has increased rapidly in metropolitan areas. All over the world, large scale underground power cable installations networks are replacing overhead transmission lines due to environmental ...

This paper presents the voltage stability assessment of power system with increasing wind energy penetration. The effects of increasing Doubly-Fed Induction Generator-based Wind Energy Conversion System (DFIG-WECS) penetration ...

The increasing power demand, the optimal use of grids, the need for economic efficiency, and the high costs associated with building new grids have created unavoidable challenges such as power line overload and excessive ...

The dynamic behavior of a PID-type fuzzy logic control depends on the appropriate choice of its scaling factors. Fixed scaling factors cannot provide adequate control performance under a wide range of operating conditions. ...

In deregulated electricity markets, generation companies (GENCOs) make unit commitment (UC) decisions based on a profit maximization objective in what is termed profit based unit commitment (PBUC). PBUC is done for the ...
