Loss Allocation Based On Power Market

With the fast development of global innovation in power market, the traditional loss allocation method under uniform instructions would not be adapted to the market demand any longer. Therefore some fair and reasonable methods should be brought up according to the market members need.Firstly, the paper presents the flow tracing algorithm used in loss allocation and the evolution of the graph theory. Therefore new algorithms adapted to different conditions are proposed according to the research of many algorithms.Because of the default of flow tracing , a new algorithm based on line using share is proposed to implement the allocation to both sides of the line at the same time. The above algorithm is proved to be justice and efficiency and the implement procedure is easy.Considering the conception that the total loss equals to all the node's net input power, the loss could be allocated to the nodes. The economic conception about margin theory is imported to realize the loss allocation using marginal coefficient. The algorithm is proved to be sensitive to economic signals and be avoidable to the subsidy in the nodes because of the positive marginal coefficient. The standard IEEE test system validates the algorithm to be correct and be suited to the large scale power system.Finally, the main research works are summarized and the prospect is included.
