Embodiment Construction

[0080] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0081] Such as figure 1 , The invention provides a site selection method for a wind-solar hybrid power station, the method is used to guide the planning and design of a large-scale wind-solar hybrid power station, and can also be used as a reference for the planning and design of a wind farm and a photovoltaic power station. According to the spatial distribution characteristics of wind energy and solar energy resources, this method aims at the main influencing factors of wind farm and photovoltaic power station site selection, considers the interaction between wind turbines and photovoltaic arrays, corrects the original model, and introduces the shadow of wind turbines Calculations, as constraints on the location of photovoltaic arrays, give specific steps for site selection of large-scale wind-solar hybrid power plants.

[0082] Specifically include the fol...

Abstract

The invention provides a site selection method for a wind-solar hybrid power station. The site selection method comprises the following steps: determining a candidate site of the wind-solar hybrid power station; performing micro site selection on a wind generation set; determining the shadow distribution of the wind generation set; determining the mounting position of a photovoltaic array; and verifying and adjusting a site selection result. According to the method, wind energy and solar energy spatial distribution characteristics and the characteristics of wind power plant and photovoltaic power station site selection are considered comprehensively, and wind power plant macro site selection and micro site selection as well as photovoltaic power station site selection and design technology are fused integrally, so that limited land resources and valuable wind energy/solar energy resources are utilized fully, and maximum economic and environmental benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of new energy power generation, and in particular relates to a site selection method for a wind-solar hybrid power station. Background technique [0002] Since the promulgation of the "Renewable Energy Law" in 2006, my country's wind power has developed explosively. The installed capacity has grown from less than 1.25 million kilowatts at the end of 2005 to 62.36 million kilowatts in 2011. In just 6 years, it has increased by nearly 50 times, almost doubling every year, and has become the country with the largest installed wind power capacity in the world. With the rapid development of wind power, the available land suitable for the development and construction of wind farms is becoming less and less. At the same time, since the Chinese government began to implement the "Golden Sun Demonstration Project" in 2009, solar photovoltaic power generation has also begun to develop rapidly. By the end of 2011, the ...
