Gas based distributed generation systems, a key to Iran buildings growing energy demand

Generally, buildings are the greatest energy consumer in the world. To satisfy their energy needs, a comprehensive solution should be considered for power generation, gas distribution network and power transmission lines. Nowadays by advent of new technologies, distributed generation seems to be a proper way. Moreover, residential sector not only is the main power consumer, but also has the highest share of gas consumption, so each effort for reclaim energy demand in buildings has tremendous effect on power and energy market. Distributed Generation (DG) technologies include electric power generation by Engines, Small turbines, Fuel cells, Photovoltaic systems and other small Renewable generation technologies. In this research, distributed generation based on gas engines and micro turbine introduced as a reliable solution generally for countries that have an access to Natural Gas or Bio Gas and particularly for Iran which has extended Natural Gas distribution network. In this paper, first the conditions of Iran energy sources, power generation and energy consumption sectors are studied in brief. Next, Energy Consumption Criteria (ECC) and Daily Consumption Chart (DCC) introduced as the graphical powerful tools for DG systems design and modeling. Each DG recommended system should be in harmony with DCC. Finally, a computer program based on EXCEL software developed to analyze different DG systems to design optimum DG system for considered building.
