A Case Study on the Use of Energy Storage in Industrial Plants with a Renewable Energy Plan

Industrial plants aim to increase their electricity generation volume due to their growing load structure. Industrial plants would also like to integrate renewables even though there is no conventional power plant in their structure. One of the biggest refineries in Turkey would like to integrate 10 MW of wind power, in addition to its conventional power plants. Wind integration will be done without the necessity of meeting the grid regulation annex-18 criteria and will be within the framework of the “Unlicensed Energy Generation Regulation”. All the energy generated from wind generation should be consumed in the plant. The structure should be configured according to this principle. The main aim of this paper is to illustrate the philosophy to be established and to show the working profiles of energy storage systems according to different scenarios. Real wind profile and real load profiles are used in the analyses. Also, the suitability of different type of wind generators according to their type and functionality are investigated for grid connected and island mode operation. For island mode operation, stability of the system for the loss of wind generation and/or storage is also studied.
