Embodiment Construction

[0068] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0069] Such as figure 1 As shown, the present invention provides a method for poverty alleviation photovoltaic point distribution and constant capacity:

[0070] S1: According to the theory of solar irradiance, calculate the photovoltaic output taking into account the hour-level fluctuation of photovoltaic output, and select a typical day with rural load characteristics;

[0071] The formula for photovoltaic output on a typical day is:

[0072]

[0073] Among them, P s is the rated power of photovoltaic power supply, α T is the power temperature coefficient of the photovoltaic panel, T is th...

Abstract

The invention discloses a poverty alleviation photovoltaic point distribution constant volume method, which comprises the following steps of: (1) constructing an upper-layer power distribution networkpoverty alleviation photovoltaic access model by taking minimum economic operation net cost, minimum photovoltaic power generation reduction quantity and minimum network loss as an upper-layer targetfunction according to typical solar photovoltaic output, photovoltaic access constraints and power grid operation constraints; (2) constructing a lower-layer poverty alleviation village photovoltaicinstallation amount investment model by taking economic benefits as a lower-layer objective function according to distributed power generation marketization constraints and poverty alleviation villagephotovoltaic installation amount investment constraints; (3) approximating the convexity of the non-convex constraint conditions in the two models; and (4) converting the double-layer planning modelinto a single-layer model for solving, and obtaining a poverty alleviation photovoltaic stationing constant volume access configuration scheme. The problem that the operation efficiency and the overall income of the power grid in the poverty alleviation region are reduced due to disordered access of the poverty alleviation photovoltaic power station to the power grid is solved.

Description

technical field [0001] The invention belongs to the technical field of new energy power generation configuration, and more specifically, relates to a method for poverty alleviation photovoltaic point distribution and constant capacity. Background technique [0002] Photovoltaic power generation has the characteristics of clean and environmental protection, reliable technology and stable income. Therefore, promoting photovoltaic poverty alleviation projects in poverty-stricken areas not only conforms to the precise poverty alleviation strategy, but also meets the requirements of the national new energy development strategy. However, the blowout development of poverty-relief photovoltaics has also imposed a huge burden on power grids in poverty-stricken areas. Considering that the distribution network in poverty-stricken areas is relatively weak, the load capacity is insufficient and there is no dynamic matching with photovoltaic output, the disorderly connection of a large num...
