摘要
随着分布式电源的大力发展,尤其是大规模间歇式可再生能源接入(如风能、光伏),使配电网从传统的简单单一电源网络转变为多电源配电网,使配电网规划变得更为复杂。对传统配电网和智能化配电网规划的内容、电源规划、网架规划等方面进行论述,并在此基础上重点论述主动配电网规划模型以及所面临的问题和研究难点,分析主动配电网规划中的关键技术,包括不确定性负荷预测和主动配电网对分布式能源的消纳能力,以及主动配电网规划的经济效益。并针对今后主动配电网规划的研究路线提出相关建议,为考虑大规模间歇式可再生能源接入配电网规划工作提供借鉴。
With the rapid development of DG, especially the access of large-scale renewable energy, traditional simple distribution network with unique source turns into ADN with multiple sources, making the distribution network more complicated. The power source and grid planning of traditional and intelligent distribution network are discussed. Based on the planning model of AND, the problems and the research difficulty of AND are focused on. The key technologies of ADN planning are analyzed, including the uncertainty of load forecasting, the ADN absorption capacity for DG and the economic benefit of ADN planning. Some suggestions for the research direction of ADN in the future are proposed,which can provide reference for the ADN planning with large-scale renewable energy access.
