PROJECT TITLE :
Probabilistic undervoltage load shedding using point estimate method
Undervoltage load shedding (UVLS) is executed as a final resort to avoid voltage instability in vital things. During this study, a sturdy UVLS theme based mostly on the point estimate method (PEM) is developed taking load uncertainties into consideration. The utilised PEM converts the continuous chance distribution functions (PDFs) of load uncertainty to discrete statistical moments. The extracted moments could represent the behaviours of original continuous PDFs. The proposed stochastic UVLS strategy is expressed as a non-linear programming problem, that is optimised using sequential quadratic programming technique. The fulfilment of the prompt theme is compared with Monte Carlo simulation technique for two IEEE fourteen-bus and IEEE 118-bus take a look at grids.
