摘要:

低压台区是电力系统中最接近终端用户的环节。首先应用环境经济学的理论和火力发电污染物排放标准分析了新能源发电的环境效益,研究分布式光伏的发电特性,并分析其接入低压台区的用电场景。接着,以低压台区可中断负荷作为调控的灵活资源,以社会效益最大化为目标建立了低压台区运行-规划双层优化模型。最后,以算例的形式说明了所提出的模型能够有效提高台区电压质量以及应对新能源出力波动的能力。

关键词: 低压台区, 分布式光伏, 可中断负荷, 双层优化模型

Abstract:

The low-voltage substation area is the link closest to the end user in the power system.Firstly,the environmental benefits of new energy power generation are analyzed by applying the theory of environmental economics and the pollutant emission standard of thermal power generation.The power generation characteristics of distributed photovoltaic are studied and the power consumption scenarios of its access to low-voltage power substations are analyzed.Then,taking the interruptible load in the low pressure substation area as the flexible resource for regulation and control,aiming at the maximization of social benefits,the two-level optimization model of operation and planning in the low voltage substation area is established.Finally,the example is given to illustrate that the proposed model can effectively improve the voltage quality of the substation area and the ability to cope with the fluctuation of new energy output.

Key words: low-voltage substation area, distributed photovoltaic, interruptible load, two-level optimization model
