Abstract

Abstract: The photovoltaic system design and application of the "Photovoltaic, Energy storage, Direct current and Flexibility" system in the "Photovoltaic Future House·DC community" building are carried out. Firstly, the key problems such as the dynamic characteristics of photovoltaic power generation are studied, and then the output model of photovoltaic power generation unit is established. Combined with the resource endowment of Zhuhai, the optimal inclination angle, array spacing and string design of photovoltaic were carried out, and the actual photovoltaic power generation efficiency was analyzed by shadow occlusion simulation. Finally, the "Photovoltaic Future House·DC community" and 21# office were used as case studies to verify the power generation effect of photovoltaic system. The results show that: in the community scenario, photovoltaic power supply configured on the roof can support the power consumption of a two-story building on the roof, and the charging and discharging strategy of the energy storage system can cooperate with the consumption of photovoltaic power generation, and the cleanliness rate of office DC electrical appliances can be significantly improved.

Key words: Photovoltaic, PEDF, DC power supply system, Building energy efficiency
