Study on the comprehensive benefit analysis model of smart distribution and utilization system

Starts from the characteristics of the smart distribution and utilization system(SDUS), typical and representative applications are summarized for further research. The comprehensive benefit analysis model of SDUS from the perspective of the entire society, taking the battery-energy storage system (BESS), distributed generation (DG), charging and exchanging station, micro grid and smart home into account, is introduced on the basis of establishing the cost benefit models of all kinds of smart businesses through extracting the correlation among the various business from a bottom-up way. Combined with an example, the comprehensive benefit of SDUS and the contribution degrees of smart businesses to the benefits were analyzed. Result shows that the use of SDUS has certain social value, and the concept of net loss sensitivity and reliability sensitivity can be used to analysis redundant relationship and obtain the contribution degree of different devices to the total net loss benefit and total reliability benefit.
