摘　　要：该文针对徐州地区零能耗太阳能住宅的用电需求,设计出一套并网型二级式光伏发电系统。首先依据住宅的最大日均用电量设计光伏发电系统的容量,进而进行选型确定光伏组件的参数和数量;然后对DC/DC变换器、DC/AC变换器和滤波器的主电路进行设计,通过分析各部分电路的输入输出关系、电压/电流纹波和滤波特性等限制条件,计算相关元器件参数;接着针对最大功率跟踪、并网电流无静差跟踪、直流母线电压保持稳定等控制要求,选定各级变换器的控制策略,并设计相关控制参数;最后利用Simulink软件建立整个光伏发电系统模型,进行仿真实验分析。结果表明:所设计的光伏发电系统无论在强光照下还是弱光照下,都能保证家用电器正常工作,且各级电路的电压电流控制效果良好。[Objective]The construction industry in China,as a major energy consumer,plays a critical role in achieving the nation’s“double-carbon”goal.According to the statistics,residential energy consumption is the highest among all types of building energy consumption and is currently the focal point of China’s energy-saving and carbon reduction initiatives.Solar energy has significant potential to reduce energy use and carbon emissions in the construction sector owing to its widespread availability,non-polluting nature,and easy integration with buildings.This paper explores the design of a photovoltaic(PV)power generation system for solar-powered residences in Xuzhou,aiming to achieve zero energy consumption for homes throughout the year.The design features passive buildings and low-energy design principles along with advanced PV technology.[Methods]The PV system capacity was determined based on the maximum value of the average daily electricity consumption of houses in Xuzhou.The number and parameters of PV modules were selected accordingly.The main circuits,including DC/DC converters,DC/AC converters,and filters of the PV grid-connected power generation system,were designed.Parameters were calculated by analyzing input/output relationships,voltage/current ripple,filtering characteristics of each part of the circuit,and other constraints to ensure normal and stable operation.Next,appropriate control strategies for each level of the converter were to meet system requirements,such as maximum power tracking,grid current tracking without a static difference,and DC bus voltage stabilization.Parameters were designed based on these control strategies.Finally,to verify the feasibility of the proposed design,a Simulink simulation model of the PV power generation system was constructed,and relevant experiments were conducted.[Results]The experimental results reveal the following:1)The PV grid-connected power generation system operated stably,meeting the target requirements for bus voltage,system output power,and total ha
