With the addition of new elements such as distributed generation, demand response, and price-sensitive loads, as well as gridsmartness, the operation and management of distribution networks have faced additional complexities. Hence, the electricity pricehas a vital role for all market participants and strongly afects the demand, generation, and subsequently, the load fow analysis inthe network. In this situation, there is a need for a load fow algorithm in which price is integrated into load fow equations.Terefore, this paper seeks to present a suitable algorithm called price-based load fow which considers the electricity price asa state variable similar to technical variables. In this situation, the price is added to the load fow equations as a new state variableand the efect of location on the price is considered. Terefore, it is possible to use the radial structure of the distribution networkand communication between adjacent buses in order to provide an efective and appropriate method to fnd the price si-multaneously with technical variables. Te numerical study on the IEEE 33-bus distribution network shows the performance ofthe proposed method. Unlike the centralized market structure, the method does not need all network information to calculatedistribution locational marginal price using optimal power fow. In this method, each bus can perform its computation only byinformation exchange with adjacent buses.
