Optimization of electricity consumption in an industrial zone with a battery system: a case study of Ikitelli industrial zone in Turkey

Abstract

Industrial power use is considerably high in Turkey. In the case of industrial zones, the three-time tariff is more economical for the owners. However, in industrial zones with considerably high energy consumption during peak hours, an alternative way is needed to reduce electricity costs. A battery-powered model was developed earlier in order to take advantage of the three-time tariff and to reduce the electric charge during peak hours. In this study, the aim was to reduce the power utility costs of industrial consumption and to mitigate CO2 emissions for businesses with high electricity costs by using solar energy. A mixed-integer optimization model was constructed as a combination of solar panels and a battery system to minimize the peak-hour grid-connected energy consumption in industrial zones. Using the consumption data from 2018, a model was implemented for a case study in İkitelli Industrial Zone in terms of 24-h scheduling. Three different alternative energy combination scenarios were studied: a monofacial PV (photovoltaic) panel system with batteries, a bifacial PV panel system with batteries, and electricity received from the grid only at the night tariff. This study found that a combined method could minimize the grid usage during peak hours.
