【摘要】：考虑到太阳能光伏发电具有波动性、间歇性、随机性的固有特征,各国电网运营商均针对光伏发电系统的并网性能提出技术要求。由于光伏发电站电气条件、地理位置及测试装置容量等限制因素,其系统的并网性能往往无法直接测量,难以验证是否满足标准要求。因此,德国能源与水行业协会(BDEW)标准《Generating plants connected to the medium-voltage network》不但要求光伏逆变器通过实验室的型式试验,且需提供与实测结果一致的仿真模型用于系统并网性能的分析与评价。依据BDEW标准,基于DIgSILENT仿真平台开展光伏并网逆变器建模仿真,分析计算实测与仿真的数据误差,开发模型验证工具,评判光伏并网逆变器模型是否满足标准验证要求,以解决光伏逆变器模型的准确性无法有效衡量的问题,为开展光伏发电站接入电网的分析提供基础。
[Abstract]:Considering the inherent characteristics of solar photovoltaic power generation, such as volatility, intermittence and randomness, grid operators all over the world have put forward technical requirements for the grid-connected performance of photovoltaic power generation systems, because of the electrical conditions of photovoltaic power stations. Because of the limited factors such as geographical location and the capacity of the test device, the performance of the system can not be measured directly, so it is difficult to verify whether the system meets the requirements of the standard. BDEW (German Energy and Water Industry Association). Standard < Generating plants connected to the medium-voltage. Network > requires not only photovoltaic inverters to pass the type tests in the laboratory. And it is necessary to provide a simulation model consistent with the measured results for the analysis and evaluation of the grid-connected performance of the system. According to the BDEW standard based on the DIgSILENT simulation platform for photovoltaic grid-connected inverter modeling and simulation. Analysis and calculation of the measured and simulated data errors, the development of model verification tools, to judge whether the photovoltaic grid-connected inverter model meets the requirements of standard verification, in order to solve the PV inverter model accuracy can not be effectively measured. It provides the basis for the analysis of the PV power station connecting to the power grid.
