Electric networks are constantly expanding and becoming more sophisticated. In restructured networks, the centralized structure of power companies is changed and replaced with decentralized companies which there are economic principles of the electricity market among them. By reviewing all references, it has been determined that reactive power pricing is not effective based on the power factor. To this end, several studies have been conducted in several papers to provide a fair and suitable process for reactive power pricing. In this thesis, in addition to reviewing and correcting some of the problems of the previous methods of reactive power market, taking into account the reactive power losses caused by active power, a new approach to clearing the reactive power market is presented. Since the flow of active power by itself causes reactive power losses, consideration of these losses is one of the main goals of this thesis. Therefore, this thesis attempts to create a fair competition between producers in addition to improving the reactive power market. To this end, while presenting a new allocation method for reactive power, various methods and structures for considering these losses in the reactive power market are presented. Also, this thesis reviews the features of renewable energy plants and presents a suitable market-based approach to the participation of renewable energy sources in the reactive power market. It should be noted that the complexity of the power grid has become more advanced with the advent of renewable energy sources, so creating a fair environment for competition among all producers become more sophisticated. At the end of this thesis, in order to take into account other objectives of the operator, a multi-objective function has been proposed that considers cost, power loss, stability and pollution. In order to investigate proposed models, simulations are performed on standard networks and the results are compared with each other as well as previous methods.
