| Abstract:Transmission loss is an important factor which affects power grid operation economy. With the deepening of China"s power market reform, market members have put forward higher requirements on reducing transmission loss and improving efficiency. This paper firstly introduces the DistFlow model and analyzes its characteristics and applicability. According to the characteristics of the transmission grid voltage, this paper proposes an economic dispatch method embedded transmission loss by setting the voltage value in DistFlow model and theoretically analyzes the impact of voltage on the accuracy of optimization. Finally, the validity of this method is proved by a case study on IEEE-57 buses system. |
