sustainable urban energy optimal supply planning using goal programming model : case study isfahan

open local energy requirements, the need for regional energy planning in the process of macro-planning can make significant energy. in this respect, the outer part of the direct effects of energy production and consumption locally effective, less energy planning processes will be huge. in this paper, the issue of continuity of energy supply, long-term access to resources and lower emissions from local after review. case study to study the optimal combination of city and electric energy supply from alternative energy such as solar, wind and gas for the period of 10 years was evaluated based on gold objectives.goal programming model is proposed, based on anticipated consumer demand, the replacement of renewable energy, capital costs and minimize pollutant emissions caused by the production, optimal portfolio for the production of electrical energy suggests.the results show that the share of solar energy and wind over the next 10 years to reach seven per cent of the total consumption and to compensate for a shortage of supply of electrical energy from the power grid around the (non-local production) is used, in these circumstances with cost same capital ratio present trends continue, emissions would be reduced for regional control.
