需求侧响应下的微网源-网-荷互动优化运行

微电网是利用可再生能源的主要方式之一,是典型的"源-网-荷"一体化系统,与智能电网、需求侧管理、分布式电源等技术联系紧密,目前已经成为能源研究的重要领域。本文通过考虑微网内源侧的不同类型分布式能源运行特点、负荷侧的不同类型需求侧响应方式以及网侧的电压约束等,建立了微网源-网-荷互动优化运行数学模型,通过滚动优化算法进行仿真分析。算例分析表明,利用本文提出需求侧响应下的管理系统模型,不仅提高了电网用电的经济性和环境友好性,而且降低了微网的负荷峰值和负荷冲击,提高了用电效率。

Optimal interactive operation of microgrid under demand response

As one of the ways to use renewable energy and a typical system of integration of power sources, power gird and power loads, micro grid technology has close links with smart grid, demand side management, distributed power and other technologies and it has become an important area of energy research. This paper discusses the micro grid research background and some common energy models. Micro grid optimization mathematical model is established considering the operation characteristics of different types of micro sources and the demand for different types of test response mode. Through rolling optimization algorithm simulation analysis, example analysis shows that with the demand side response management system model, it can not only improve the electricity economic and environmental friendly, but also reduce the peak load and shock load of micro grid and improve the power efficiency.
