中文摘要	Transaction planning and congestion management are significant issues to ensure secure and economic operation of electricity market, whereas conventional methods are on the basis of intricate mathematical derivation, and the calculation process is characterized by the adjustment of the output of units as the core of iteration so it lacks enough market features. After the detailed analysis on implication of different prices in electricity market and the relation to each other, the authors proposed an algorithm in which the price is used as control variable for the transaction planning and congestion management. On the basis of unconstrained transaction planning, by means of judging and adjusting the prices of congestion lines as well as the prices of generating nodes, a new price equilibrium in power grid is achieved, and then the outputs of units and power flows of transmission lines are changed to eliminate congestion. Using the proposed algorithm, the scarce extent of resources and supply-demand relationship can be weighed and reflected by price, the economic and physical meaning of whole calculation process are clear, and the guidance effect of price for optimal resource allocation is brought into relief. Calculation results of IEEE 14-bus test system show that the proposed algorithm possesses rapid convergence speed and its calculation is accurate.
