Economic Analysis of Generation and Distribution Integrated System with High Penetration Distributed Generation

With the rapid development of distributed generation and advancement of power system, the integration of generation and distribution becomes an important operation mode in the future and distributed generation helps to improve the economy of incremental distribution. This paper quantifies the main cost-benefit of generation and distribution integrated system, then proposes an economic analysis method of the distribution integration system, which takes into account the transformation of power grid caused by high penetration distributed generation. Based on the analysis of typical scenarios, the conclusions can provide guidance for the planning and operating of generation and distribution integrated system. (paper)
