Active Distribution Network Cost Allocation Method Based on Distribution Factor Method

doi:10.11930/j.issn.1004-9649.201906010

Abstract

Abstract: Considering the characteristics of active distribution network’s flexible topology and variable power flow, the traditional method of cost allocation is no longer applicable. Therefore, this paper proposes a new cost allocation method for the active distribution network based on the generalized load distribution factor (GLDF). By calculating the distribution factor of nodes and topology, the proposed method can dynamically adapt to the changing operation mode of active distribution network. Through network loss modification and analysis of the full load level utilization, the DC power flow model kernel of the distribution factor method is improved. This method not only has good adaptability to active distribution network, but also can be used to objectively measure the usage of different load nodes in different operation modes. Moreover, this method is helpful to guide the market users to adjust their electricity consumption behavior. The feasibility and rationality of the method is verified by an example.

Key words: active distribution network, distribution cost allocation, distribution factor method, network loss modification, full load level
