Short term electrical load forecasting for an urban 11 KV feeder using machine learning techniques
Journal Title: Journal of Multidisciplinary Sciences - Year 2019, Vol 1, Issue 1
Abstract
Accurate electricity load estimation is an important issue for the operation of the power system and it is one of the essential works of future power planning for large cities. Every power prediction model has its own benefits and drawbacks and has its particular application range. Researchers categorized the load energy forecasting as Short-Term Load Forecasting (STLF), Medium-Term Load Forecasting (MTLF) and Long-Term Load Forecasting (LTLF), which entirely depends on time in which estimation is scheduled. As electricity load forecasting can be seen as a machine learning problem, so a number of automated methodologies and models are included in the literature review. In this work, we aim to explore and implement state of art machine learning techniques like Polynomial Regression, Support Vector Regression (SVR) and Artificial Neural Networks (ANN) in order to predict the short term and medium-term load consumption for the historical data accurately. For this study, hourly load data of an Urban 11 KV Feeder was collected from the 220 KV grid station. Weather parameters like temperature, pressure and humidity data for the particular region were taken from Lahore Meteorological Department. Data were divided into several datasets (daily, weekly and monthly) to achieve short term and medium-term electrical load prediction using aforementioned techniques. Input parameters used in this study were temperature (both dry and wet), humidity and pressure while predicted hourly load demand was used as output. Final results tables show that the performance of the SVR predictor is much better than other techniques both in short term and medium load forecasting.
