Economic analysis of home-based micro-grid under non-real-time pricing mechanism

摘要

The subject addressed is to discuss economic efficiency of home-based micro-grids under non-real-time pricing mechanism. Firstly, configurations of investment and return are decomposed in terms of home-based microgrid under the background of China's current renewable generation policies and residential non-real-time electricity pricing mechanism. Secondly, a mathematic model of cost/benefit is developed to analyse the economic efficiency during its whole life cycle. One practical case from a demonstration project in Guangzhou is provided to illustrate the analysis in this paper. Furthermore, sensitivity analysis is applied to main factors which potentially impact on economic efficiency of home-based micro-grid system. Results show that price and quality of main equipment are the most potential keys to enhance economic incentives of home-based micro-grid power system in China.
