语法

模拟的输入在Jupyter Notebook的步骤3中加载(不确定性分布除外,它们在步骤6中加载)。

步骤3的代码语法如下:

分析选项

simulation_options = build_simulation_options(
    number_of_years=5,
    number_of_simulations=5000
)

请注意,最大模拟次数为250,000。(即,年数×模拟次数不能超过250,000。)

天气文件

weather_file_path = "Data/sydney.pvw"
weather_data = load_weather_data_from_pvw_file(weather_file_path)

系统配置

定义光伏系统的输入分为六个组。 这些组中输入的语法如下表所示。

module_info = build_module_info()
optical_settings = build_optical_settings()
system_info = build_system_info()
thermal_settings = build_thermal_settings()
electrical_settings = build_electrical_settings()
operational_settings = build_operational_settings()

输出选项

result_options = build_result_options(
    bin_min=0.9,
    bin_delta=0.01,
    p_values=[5, 10, 90, 95]
)

在分组中包含输入的示例

示例:将分布应用于GHI和可用性。

electrical_settings = build_electrical_settings(
    inverter_efficiency = 0.97,
)
operational_settings = build_operational_settings(
    yield_modifier=1,
    availability=0.99,
    dc_health=0.99,
)

输入名称及其分组

在步骤3中未定义的任何输入将采用其默认值。
