中德光伏发电并网标准技术要求异同分析

为保障规模化光伏并网后的安全稳定运行，最大限度在区域电网内接纳光伏装机容量，世界主要光伏应用大国均出台了与各自国家电网相适应的光伏发电并网技术标准。中国和德国已成为世界光伏并网发电大国，在光伏并网标准制定与光伏并网管理方面也走在世界前列。2012年，德国的新能源法案EEG要求接入中压电网的光伏发电系统必须满足BDEW《Generating Plants Connected to the Medium—Voltage Network》标准，中国则在2012年制订了GB／T19964-2012《光伏发电站接入电力系统技术规定》。总体来看，两国标准在光伏并网的技术要求与测试方法上既有相似之处也存在一定差异。该文将结合中国及德国现行并网技术导则，针对技术要求、测试项目与测试方法等内容的异同开展对比分析。

Comparative Study on Technical Demands of PV Generation System Between China Standards and German Standards

To ensure security and stability of the power grid integrated with the maximum photovohaic （PV） plants, each of the world leading PV application countries puts forward its own technology standards for the PV connected to the grid in confor- mity with its grid conditions. China and Germany have become the world＇s largest two countries in terms of the PV plant capacity, and the PV generation management for the power grid in these two countries is also leading in the world. In 2011, Germany＇s Energy Source Act （EEG） stipulated that the PV systems access to the medium-voltage grid meet the BDEW ＂Generating Plants Connected to the Medium-Voltage Network＂ standards. In 2012, China drew up its GB/T 19964-2012 ＂Technical Requirements for Connecting Photovohaic Power Stations to Power System.＂ Overall, the two standards have both similarities and some differences. This paper compares the existing Technical Guidelines for PV generation in China and Germany. The similarities and differences are analyzed in terms of technical requirements, methods of test items and test criteria.
