MODIFIED NARX NETWORK FOR LOW VOLTAGE CONSUMER LOAD PREDICTION

Ayodele Isqeel ABDULLATEEF*, Momoh-jimoh Eyiomika SALAMI, Ismaila Bayo TIJANI, Mosud Taiwo AJALA

This paper is a continuation of our previous work on Nonlinear autoregressive witheXogenous input (NARX) for load prediction. Application of NARX network inreal-time might be difficult since the tapped delay was selected by trial and error,leading to nine hidden neurons which makes the network complex. This NARXnetwork was modified based on Genetic Algorithm (GA) and Differential Evolution(DE) res...

Development of Load Frequency Control of Two Area Interconnected Network Incorporated with Distributed Energy Sources

Adamu, Ahmed Kana*, A. B. Kunya, A.S. Abubakar

The frequency of power systems is highly sensitive to load changes, and the increasing integration of distributed energy sources (DESs) further complicates frequency stabilization. To address these challenges, Load Frequency Control (LFC) is implemented to maintain frequency within acceptable limits. This work proposes a grasshopper optimization algorithm based on proportional integral derivative ...

MODULAR MULTILEVEL CONVERTER WITH STATEFEEDBACK CONTROLLER FOR HARMONICS SUPPRESSION

A.U. Lawan*, A.Abdulkarim, G.S. Shehu, A. Kunya, I.S Madugu

Control of submodule capacitor voltages and the circulating current within modularmultilevel converter (MMC) is essential to MMC performance. The circulating current hasan influence on the losses, rating of the power devices and voltage ripple. The circulatingcurrent tends to have csurrent harmonics due to the voltage disturbance on the submodulecapacitor voltages. To decrease the influence of the...
