Modified Gravitational Search Algorithm for Energy Demand Estimation of Turkey

Abstract

Estimation of energy demand beforehand is a quite significant problem in respect of economy and sources ofcountry. In this study, Gravitational Search Algorithm (GSA) was modified by making some innovations in GSAand called as Modified Gravitational Search Algorithm (MGSA). Energy demand estimation is conducted throughthe relationship between the increase in economic indicators in Turkey and energy consumption. Estimation wasactualized by using gross domestic product (GSYH), importation, exportation and demography for energy demandestimation and both linear and exponential equations. Energy demand between the years 2017-2037 was predictedby using the data belong to 1997-2011. The years between 2012 and 2016 were used as test data. It was observedthat the results acquired via MGSA estimate better compared to GSA results.
