  7. Abstract:
  8. Electricity is one of the most important kinds of energy and also one of essential needs of humans for maintaining their life. Due to growth of costumer’s load and In order for delivering high reliable power to the consumers, the structure of the power grid must be expanded and/or demand side management policies like demand response programs must be taken into consideration. One of the most important and less-focused aspects of power grid expansion planning is, distribution system expansion planning. Distribution system expansion planning (DSEP) is an important task of electric distribution companies and operators in order to appropriately supply their customers load with the minimum cost and high reliability. The emergence of distributed generation (DG) in distribution networks has affected the planning and operation problems of these networks. The wind-based DGs are increasingly employed in distribution systems due to their inexhaustible and non-polluting features. However, the intermittent nature of the wind speed has made the output power of these resources also intermittent and stochastic. To settle this defect, the energy storage units can be employed.In this research for distribution planning aims, we have used an incentive-based Demand Response Program as a tool to soften load profile of costumers to somehow decrease or defer the chance of adding new assets into distribution system.we also have considered the impacts of integrating new Distributed Generation Systems (Wind Farms) into the distribution system and also the impacts of Battery Energy Storage Systems(BESSs) as two of most important planning tools for minimizing the overall cost of distribution companies and operators. The problem has been solved with a Mixed-Integer Linear Programming approach , Simulations have been done and the results that represent the significant cost reduction of Distribution System are shown in the simulation and results section of this research
