主动配电网技术的研究现状与发展

Research status and development of active distribution network technology

随着分布式电源的大规模接入,网络功率潮流已经由传统的单向潮流问题转化为复杂的双向潮流问题。配电网的复杂度增加,传统的能量管理方法显然无法适应日益加深的配电网能量调度问题。主动配电网因其主动性、灵活性与协调性,已经日渐成为研究的主流。本文主要介绍了虚拟发电厂和微网的主要概念,以及主动配电网的核心技术及其研究现状。

With the access of large-scale distributed generation, network power flow has been transformed from the traditional one-way flow problem as a complex two-way power flow problem. With the increased complexity of the distribution network, the traditional energy management approach is clearly unable to adapt to the deepened distribution network energy dispatch problems. Active distribution network has increasingly become the mainstream research because of its initiative, flexibility and coordination. This article describes the main concepts of virtual power plants and micro-grid, as well as the core technology and research status of active distribution network.
