本文研究微电网在应对配电网净负荷爬坡问题中的应用,通过优化方法确定微电网爬坡能力,并开发协调模型以实现两者负荷的协调。

摘要:

尽管太阳能具有诸多优势,其部署将显著改变典型电力负荷曲线,从而 necessitating 传统配电电网管理实践的改变。特别是,由于早 evening 小时同时发生太阳能发电下降和负荷增加,产生的净负荷爬坡是需要仔细处理的主要运营问题之一。本文利用微电网提供一种可行的本地化解决方案,以应对这一挑战,同时避免电力公司昂贵的投资。为此,首先通过 min-max 优化确定微电网的爬坡能力,其次开发微电网最优调度模型,以协调微电网净负荷与配电电网净负荷,以解决爬坡问题。对具有一个微电网的测试配电馈线进行数值模拟,展示了所提出模型的有效性。

英文摘要:

In spite of all advantages of solar energy, its deployment will significantly change the typical electric load profile, thus necessitating a change in traditional distribution grid management practices. In particular, the net load ramping, created as a result of simultaneous solar generation drop and load increase at early evening hours, is one of the major operational issues that needs to be carefully addressed. In this paper, microgrids are utilized to offer a viable and localized solution to this challenge while removing the need for costly investments by the electric utility. In this regard, first the microgrid ramping capability is determined via a min-max optimization, and second, the microgrid optimal scheduling model is developed to coordinate the microgrid net load with the distribution grid net load for addressing the ramping issue. Numerical simulations on a test distribution feeder with one microgrid exhibit the effectiveness of the proposed model.
