【摘要】：风电在我国的发展由最初的分散零星开发、就地消纳模式向规模化、集约化和远程、高电压输送模式转变。但是这一转变模式也带来一些问题,如风电的无序过度开发导致风电消纳能力低下,出现大规模弃风和调峰困难现象,不但浪费资源而且给系统运行带来一定的困难和危险。黑龙江作为我国风能资源最为丰富的省份之一,为了合理规划黑龙江的风电开发及其电量消纳,本文开发了风电消纳能力分析与评估系统。首先,经过对目前已有风电消纳理论进行深入分析,总结得出了目前影响风电消纳的因素和存在的风电消纳方法；其次,本文定义了关口属性,方便了开发过程中各种电力、电量的准确快速获取,同时也避免了诸如新增关口或关口属性变更后对相应公式的修改；最后,根据黑龙江省地理特点及风能资源分布特点对黑龙江进行地区划分,方便对不同地区风电消纳能力的计算。从系统调峰的角度提出了本文风电消纳能力的算法,对黑龙江风电消纳能力进行了分析与计算,并开发了人机界面友好的系统。该系统通过分析黑龙江现有的电能数据,从系统调峰的角度分析黑龙江风电消纳能力,避免风电的无序开发和建设,实现风能的充分合理利用,为未来黑龙江电网的电源和电网规划提供必要的技术支持。
[Abstract]:The development of wind power in China has changed from initial scattered development and local absorption mode to large-scale, intensive and remote, high-voltage transmission mode. However, this transformation mode also brings some problems, such as the unordered overdevelopment of wind power, which leads to the low capacity of wind power absorption, the phenomenon of large-scale wind abandonment and peak shaving, which not only wastes resources but also brings some difficulties and dangers to the system operation. Heilongjiang is one of the most abundant provinces of wind energy resources in China. In order to reasonably plan the wind power development and power consumption in Heilongjiang, this paper develops the wind power capacity analysis and evaluation system. First of all, through the thorough analysis of the existing wind power absorption theory, the paper summarizes the factors that affect the wind power consumption and the existing wind power absorption methods; secondly, this paper defines the gate attribute, which facilitates the development of various kinds of electric power. At the same time, it avoids the modification of the corresponding formula after the change of the new gate or the attribute of the gate. Finally, according to the geographical characteristics of Heilongjiang Province and the distribution characteristics of wind energy resources, the region of Heilongjiang Province is divided. It is convenient to calculate the absorption capacity of wind power in different areas. From the point of view of system peak shaving, this paper puts forward an algorithm of wind power absorption capacity in this paper, analyzes and calculates the wind power absorption capacity of Heilongjiang province, and develops a man-machine interface friendly system. Through analyzing the existing electric energy data in Heilongjiang, the system analyzes the wind power absorption capacity of Heilongjiang from the angle of peak shaving system, avoids the disorderly development and construction of wind power, and realizes the full and reasonable utilization of wind energy. Provide necessary technical support for power supply and power network planning of Heilongjiang power grid in the future.
