  7. Abstract:
  8. The present work has proposed an integrated methodology for combined gas & electricity distribution network expansion planning, which considers network expansion constraints (substation installation, feeder/pipeline installation, etc), load growth, and conversion technologies. The planning aims to determine the optimal reinforcement of existing energy network to meet the load growth in the planning horizon. To take the advantages of new technologies, CHP, fuel cell, & microturbine have been included in the problem.This paper employs gravitational search algorithm (GSA) to solve multi-objective problem, including minimization of cost, voltage drop, & pressure drop. GSA that introduced in 2009, is one of the most efficient heuristic algorithms and its ability to solve optimization problems, much more than others like genetic algorithm and particle swarm optimization. Modified versions of GSA have been presented yet to solve different kinds of engineering problems such as aerodynamics, truss structures, economic dispatch, energy hub, bioinformatics, & image processing. Accordingly, the proposed model for energy network expansion is applied to 10 bus system. The results verify the effectiveness of the present method
