摘要:

可信容量是评价分布式电源容量价值的重要指标。针对西部某地区风电/水电富集区域处于配电网末端、分布式电源分散式并网、网架结构薄弱的特点,提出该区域与外网不同的运行策略下计及网架约束的风电机组可信容量评估方法,并采用局部电网调度和全局可信容量计算两步算法,计算系统的等效载荷能力,量化分析多类型电源富集区域并网对系统充裕性的影响。以西部某富水地区电网为例,计算了风电机组可信容量,同时研究了局部电网与外部电网3种不同运行方式对系统整体充裕性的影响,并提出相关运行建议。

关键词: 风电机组可信容量, 网架约束, 等效载荷能力, 优化调度

Abstract:

Credible capacity is an important index to evaluate the capacity value of distributed generation. According to the characteristics in western region of abundant wind power/hydropower located in the terminal of distribution network, distributed generation dispersedly accessing to the grid and the weak grid structure, this paper proposes the wind power credible capacity evaluation method considering grid constraint under the different operation strategies in local grid and intergration grid, adopts the local power grid scheduling and global credible capacity two-step algorithm to calculate the equivalent load capacity of system, and quantitatively analyzes the effect of grid connection in multiple types of power enrichment area on system adequacy. Taking a certain water-enriched regional grid in western region as example, we calculated the capacity credible of wind power, at the same time researched the influence of three different operation modes of local and external power system on the overall adequacy of system, and proposed relevant operation suggestions.

Key words: credible capacity of wind power, grid constraints, equivalent load capability, optimal scheduling
