Coordinated operation of gas-electricity integrated distribution network with CCHP and renewable energy sources

This article, proposed a method to coordinated utilization of gas-electricity integrated distribution system, including CCHP systems and renewable energy sources, considering AC load flow analysis in an electric grid and the calculation of gas consumption in a gas grid. In this research as you will see, an effective method proposed to prevent transmitting of power generation swings of renewable sources over trans-regional power line and maximum utilization of renewable sources. The proposed model tested on a modified distribution power grid IEEE 33 and 24-node-gas grid. Results show that total expense of adjustment in Conventional design will rise dramatically by increasing of unit. While in the presented design, adjustment expense will remain stable and increase slightly.
