Abstract

The increasing amount of DER components into distribution networks involves the development of accurate simulation models that take into account an increasing number of factors that influence the output power from the DG systems. This paper presents two simulation models: a PV panel model using the single-diode four-parameter model based on data sheet values and a VRB system model based on the efficiency of different components and the power losses. The models were implemented first in MATLAB/Simulink and the results have been compared with the data sheet values and with the characteristics of the units. Moreover to point out the strong dependency on ambient conditions and its influence on array operation and to validate simulation results with measured data a complex model has also been developed. A PV inverter model and a VRB inverter model, using the same equations and parameters as in MATLAB/Simulink, has also been developed and implemented in Power Factory to study load flow, steady-state voltage stability and dynamic behavior of a distribution power system.

开发配电网仿真系统的工具，并通过测量验证

随着配电网络中DER组件数量的增加，需要开发精确的仿真模型，以考虑影响DG系统输出功率的越来越多的因素。本文提出了两种仿真模型:基于数据表值的单二极管四参数PV面板模型和基于不同组件效率和功率损耗的VRB系统模型。该模型首先在MATLAB/Simulink中实现，并与数据表值和机组特性进行了比较。此外，为了指出对环境条件的强烈依赖及其对阵列运行的影响，并利用实测数据验证仿真结果，还建立了一个复杂的模型。采用与MATLAB/Simulink相同的方程和参数，建立了光伏逆变器模型和VRB逆变器模型，并在电厂中实现，用于研究配电系统的负荷潮流、稳态电压稳定性和动态行为。
