Peramalan beban listrik memegang peranan yang sangat penting bagi efisiensi dan kinerja dari PLN. Berbagai jenis metode dipakai untuk mendapatkan hasil peramalan beban yang akurat agar daya yang dikirimkan sesuai dengan kebutuhan listrik dari konsumen. Skripsi ini membahas peramalan beban jangka pendek satu minggu ke depan dengan menggunakan Jaringan Syaraf Tiruan (JST). Peramalan beban jangka pendek sangat dipengaruhi oleh faktor-faktor cuaca, yang dalam hal ini menjadi masukan JST, yaitu : Suhu, Kelembaban, Tekanan udara, dan Kecepatan angin. Data yang digunakan untuk pembelajaran adalah data sebenarnya sepanjang tahun 2011. Arsitektur yang digunakan adalah feed-forward dan algoritma yang dipakai adalah algoritma backpropagation. Berdasarkan hasil didapatkan nilai MAPE terbaik sebesar 1.8 % dan untuk 10 kali running sebesar 2.65 % sehingga berada di bawah ambang kesalahan peramalan. ABSTRAK
Electrical load forecasting has an important role for efficiency and performance from PLN.Various types of methods have been used to provide an accurate load forecasting on purpose that the transmitted power appropriates the demand of consumers. This research will discuss short term load forecasting using Artificial Neural Network (ANN). Short term load is influenced by weather factors, those will become input of ANN, i.e. : Temperature, Humidity, Pressure, Wind speed, Data used for study are actual data in 2011. Architecture used for this research is feed-forward and Algorithm that is used is backpropagation . The final result shows that the best MAPE is 1.8 % and for 2.65 % for 10 iterations which are below the forecasting error limit., Electrical load forecasting has an important role for efficiency and performance from PLN.Various types of methods have been used to provide an accurate load forecasting on purpose that the transmitted power appropriates the demand of consumers.
