Recent trends of Short-Term Load Forecasting (STLF) is a key issue to regulate power in the electricity market. Many researchers have performed research in this area but it still needs an accurate and robust load forecast method. In this paper, we propose a novel Artificial Immune Network (AIN)-based approach to predict forecast load depending on last three days’ mean actual load. The approach creates an immune memory using time series to forecast one-day ahead hourly loads. The method takes hourly loads separately as an individual daily time series and considers it as an antigen, an affinity is calculated between an antigen and antibody in Immune Networks (INs). A cross-reactivity threshold is used to find the appropriate cluster for an antigen in an immune network. The historical dataset of Poland is trained and tested by this method which predicts more accurately compared to the most recently existing STLF methods, such as simple Nearest Neighbor (NN), Multilayer Perceptron (MLP), Fuzzy Estimators (FE), and Artificial Immune System (AIS).
