摘要:

配电网担负着电能的配送任务,传统配电网的电能传送是单向的,随着分布式电源大量接入,配电网的电能可能出现双向流动。由于分布式电源具有随机性和间歇性的特点,增加了配电网运行控制的难度。为了满足大规模分布式电源接入的要求,在北京延庆建设交直流混合主动配电网,提高配电网的能源配送和优化能力,支持高渗透率分布式能源的充分消纳,降低系统损耗,提高设备利用率,实现高可靠高质量供电,延缓增容建设投资。

Abstract:

Traditional distribution networks undertake the function of distributing energy and providing electricity consumption, therefore the flowtransferringis unilateral. The increasing amount of distributed generation (DG) in todays highly complex restructured power networks change it to bidirectional flow. Due to the randomness and intermittence of DG, flow fluctuates wildly in a degree, which makes the distribution infrastructure cannot work in economical and efficient ways. For the better energy transferring ability of DG, provide high-quality power, Beijing Power Grid build the controllable and observable active distribution(ADN) in energy transferring and distribution operator system field, for the entire energy consumption of high-permeability DG, achieve the aim of efficient energy use and high-quality and high-reliability power supply.

Key words: active distribution networks, multi-source, distribution generation, energy internet, AC/DC hybrid smart grid
