Abstract: The gradual increase of the distributed generation connected to distribution network has exerted an impact on the cost and benefit of the distributed generation and distribution network. On the basis of summarizing the current business model of grid-connected distributed generation, this paper calculates the cost and benefit of power company and independent investor after distributed generation connected to distribution network with using net present value method and payback period method. And then the paper compares the cost and benefit of grid-connected distributed generation under different business models and different load mode. The calculation results show that, in the economic aspect, distributed generations bring more disadvantage to power company under the current business models, and independent investors gain more benefit when using more power.

Key words: distributed generation, cost-benefit analysis, grid-connected business model, independent investor, distribution network
