【摘要】：微网中的分布式电源大多利用可再生能源发电,能源清洁,符合国家可持续发展的战略要求。当前很多分布式电源发电技术已十分成熟,并且正在逐步地商业化,例如风电、微型燃气轮机、小水电、燃料电池、光伏发电等等。随着微网技术的发展与成熟,微网的调度以及经济运行也日益受到人们的关注。本文综合考虑了多种分布式电源,研究了它们的发电原理、出力特性以及环境效益,建立了各种电源的出力模型。在传统调度方法的基础上,考虑了需求侧,建立了综合考虑扩展实时电价、用户响应、可中断负荷的实时优化调度模型。本文把一天分成24个小时,以发电成本和用电费用最低为目标,运用合理的调度策略对每一小时进行调度。并网模式下,不考虑蓄电池且合理的向大电网买电；孤岛模式下,考虑了可中断负荷。与原始数据相比,新的调度策略在不影响用电质量的基础上,成本更低,并达到了削峰填谷的作用。
[Abstract]:Most of the distributed power generation in microgrid uses renewable energy to generate electricity, which is clean and meets the strategic requirements of national sustainable development. At present, many distributed power generation technologies are very mature and are being commercialized step by step, such as wind power. With the development and maturity of micro grid technology, the dispatch and economic operation of micro grid have been paid more and more attention. In this paper, a variety of distributed power sources are comprehensively considered, and their generation principles, characteristics of power generation and environmental benefits are studied, and various power generation models are established. On the basis of the traditional dispatching methods, the demand side is considered. In this paper, a real-time optimal dispatching model is established, which considers the expansion of real time electricity price, user response and interruptible load. In this paper, we divide a day into 24 hours and aim at the lowest generation cost and electricity cost. In grid-connected mode, the battery is not considered and reasonable electricity is bought from large power grid. In isolated island mode, interruptible load is considered. The new scheduling strategy can reduce the cost without affecting the power quality and achieve the function of cutting the peak and filling the valley.
