分布式光伏发电与主动配电网的协调发展

Coordinated Development of Distributed Photovoltaic Generation and Active Distribution Network

首先介绍分布式光伏发电的基本概念和特点,并分析了分布式光伏发电接入可能对配电网产生的不利影响,以及传统配电网对分布式光伏发电推广应用的制约;在探讨如何利用主动配电网(active distribution network,ADN)技术解决分布式光伏发电接入问题后,对主动配电网的一些关键技术进行了分析和总结;最后介绍了分布式光伏发电与主动配电网几个典型的应用领域,并强调了二者在政策规划、技术规范和实验示范等方面协调发展的重要性。

In this paper, basic concept and characteristics of distributed photovoltaic generation （DPG） were first introduced. However, integrating more and more DPG into distribution grid may have adverse effects on distribution grid, while conventional distribution grid also constrains the wide application of DPG. Both issues were discussed in details. To address these issues, active distribution network （ ADN ） technology was applied and analyzed. On this basis, the key technologies of ADN were summarized. Finally, several typical combined applications of DPG and ADN were given. Moreover, coordinated development of these two technologies in policy planning, technical requirements and demonstration were emphasized.
