Soumya Kundu, Jacob Hansen, Jianming Lian, Karan Kalsi

摘要:

由于与负荷行为相关联的不确定性,电力负荷在提供电网辅助服务方面的潜力通常是有限的。负荷控制计划的预期不确定性的知识总是会产生更好的知情控制策略,开辟了提取最大负荷控制潜力而不影响电网运行的可能性。在频率响应负载控制的背景下,概率不确定性分析框架,以量化的目标和实际负载响应之间的预期误差,在负载动态的不确定性。一个封闭形式的最优需求的灵活性,最大限度地减少实际和承诺的灵活性的预期误差的表达。通过对电热水器整体的蒙特卡罗模拟,验证了分析结果。

英文摘要:

Potential of electrical loads in providing grid ancillary services is often limited due to the uncertainties associated with the load behavior. A knowledge of the expected uncertainties with a load control program would invariably yield to better informed control policies, opening up the possibility of extracting the maximal load control potential without affecting grid operations. In the context of frequency responsive load control, a probabilistic uncertainty analysis framework is presented to quantify the expected error between the target and actual load response, under uncertainties in the load dynamics. A closed-form expression of an optimal demand flexibility, minimizing the expected error in actual and committed flexibility, is provided. Analytical results are validated through Monte Carlo simulations of ensembles of electric water heaters.
