Optimal scheduling of electrical power in energy-deficient scenarios using artificial neural network and Bootstrap aggregating

• Optimal load-shedding strategy is done with Bootstrap aggregating algorithm.
• Load-shedding strategy is also implemented with ANN algorithm.
• The results of Bootstrap aggregating algorithm are superior to those from ANN.

In a developing country like Pakistan, where the electrical power demand is more than the generated power, maintaining the power system stability is a big challenge. In such cases it becomes, thus, essential to shed just the right amount of load to keep a power system stable. This paper presents a case study of Pakistan’s power system where the generated power, the load demand, frequency deviation and the load shed during a 24-h duration have been provided. The data have been analyzed using two techniques; the conventional artificial neural network (ANN) by implementing feed forward back propagation model and the Bootstrap aggregating or bagging algorithm. The simulation results reveal the superiority of the Bootstrap aggregating algorithm over a conventional ANN technique using feed forward back propagation model.
