Abstract

According to Decision No. 13/2020/QD-TTg dated April 6, 2020 by the Prime Minister on the mechanism to encourage the development of rooftop solar power in Vietnam will expire after December 31, 2020. To harmonize the interests of households and the Electricity of Vietnam (EVN), a grid-connected rooftop solar power system with storage will be a solution worthy of attention. This paper builds a grid-tied solar power model with storage system. The model will ensure to storage of excess electricity from the solar power system and will not use grid electricity for the storage system. From there, evaluate the impact of the rooftop solar power system with the storage system on the household’s load demand in two cases of cost optimization and grid operation optimization. In addition, the paper will evaluate in detail the investment efficiency of this type of rooftop solar power from the perspective of households. The results show that the grid-connected rooftop solar power system with storage system brings many benefits in terms of grid operation such as: no pressure on the power grid, reduced peak demand for households, increased energy efficiency, and increased energy efficiency. Flat load graph, reducing the demand for electricity at peak hours. But in economic terms, the interests of households and those of EVN are opposite.
