Contribution of renewable energies in power systems is increasing due to continuous growth of wind and solar generators. Because of intermittency and uncertainty of these resources, conventional reliability evaluation methods are not applicable and different techniques have been developed to model these generators. However, most of these methods are time-consuming or may not be able to keep time dependency...
Deployment of renewable energies in networks can affect their reliability and security. This paper presents a reliability evaluation methodology in the presence of wind turbines and photovoltaic panels illustrated with IEEE-RBTS system chosen for study. The aggregated clean resources feed load points in micro grid configuration. The use of analytical methods provide partial information of reliability...
Renewable intensive bulk power system planning and operation considerations are getting high importance due to huge pressure imposed by environment-friendly policies and uncertainties in the fossil-fuel based investments. This paper addresses a number of influential economic and reliability issues for renewable generation entry to a deregulated electricity market. Geothermal power penetration, wind...
This paper explains a fast acting Under Frequency Load Shedding and restoration scheme. This load shedding technique has an added advantage of selecting the amount of load which is to be dropped at a particular frequency threshold. The amount of load dropping is selected based on the rate of change of the frequency. Automatic restoration of loads is discussed with engaging a command signal from the...
