Regional Energy Portfolio Construction: Case Studies in Turkey

Abstract

A geographically large country has different energy resource availabilities and varying environmental, economic and social impacts on the regional energy requests. District energy management is becoming the focus of research, where these differences are to be focused. Hybrid use of the energy resources as a response to the regional requests, forces regional plans. This study has the aim of designing hybrid energy portfolio model with minimum environmental costs and minimum emissions while the rate of energy investment to the regional revenue is increased. The portfolio is constructed based on five resources: solar energy, wind energy, geothermal energy, biomass energy and hydropower besides natural gas. Since in none of the demand is totally responded by renewables only. The lower and upper bounds of European Union allowances are taken as range of targets. Fuzzy Goal Programming method, an intelligent method for handling the uncertainties, is implemented to maximize the membership in the allowed ranges of objectives. Case studies are performed for Yatagan a southwest region of Turkey and Corlu a northwest region, where different renewable sources are available. Remarkable dissimilarities are evaluated that will enlighten the future regional policies.
