摘要:

分布式可再生能源资源近年来因可再生能源技术成本下降、广泛的联邦和州激励措施以及提高负荷点可靠性应用而受到广泛关注。然而,这种增长的普及正在通过增加显著的波动性改变传统的消费负荷曲线,进一步挑战电力供需平衡。本文研究了微电网在有效捕捉由prosumers引起的配电网净负荷波动中的应用。微电网提供了一种可行的本地化解决方案,同时避免了电力公司对现有电力基础设施进行昂贵投资的需要。本文提出并开发了一个以灵活性为导向的微电网优化调度模型,以协调微电网的净负荷与配电网中聚合消费者/prosumers的净负荷,重点在于爬坡问题。所提出的协调旨在捕捉小时间和小时内净负荷的波动性。在具有一个微电网和多个消费者/prosumers的测试配电网上的数值模拟展示了所提模型的有效性。

英文摘要:

Distributed renewable energy resources have attracted significant attention in recent years due to the falling cost of the renewable energy technology, extensive federal and state incentives, and the application in improving load-point reliability. This growing proliferation, however, is changing the traditional consumption load curves by adding considerable levels of variability and further challenging the electricity supply-demand balance. In this paper, the application of microgrids in effectively capturing the distribution network net load variability, caused primarily by the prosumers, is investigated. Microgrids provide a viable and localized solution to this challenge while removing the need for costly investments by the electric utility on reinforcing the existing electricity infrastructure. A flexibility-oriented microgrid optimal scheduling model is proposed and developed to coordinate the microgrid net load with the aggregated consumers/prosumers net load in the distribution network with a focus on ramping issues. The proposed coordination is performed to capture both inter-hour and intra-hour net load variabilities. Numerical simulations on a test distribution feeder with one microgrid and several consumers and prosumers exhibit the effectiveness of the proposed model.
