Abstract

This paper describes a modelling framework developed in Matlab/Simulink that has been used to study, analyse and improve the network integration of Wave Energy Converters (WECs). It presents and discusses a generic, time domain, resource-to-wire model that can be used to explore the effects of: increased device numbers, array size and physical positioning; and the adjustment of control parameters. The three-dimensional wave field is modelled as non-stationary, with statistical characteristics that are extracted from measured wave elevation time series to simulate increasingly realistic sea conditions. Each heaving buoy has high-pressure oil power take off with on-board energy storage, driving Doubly Fed Induction Generators (DFIGs). The results obtained from simulations using this model are used to demonstrate the overall effects of storage on real power production, and the effects of imaginary power control on network voltage profile. The opportunities for improved network integration are identified and discussed.

对连接薄弱农村电网的波浪能转换器阵列进行建模

本文描述了在Matlab/Simulink中开发的一个建模框架，用于研究、分析和改进波浪能转换器(WECs)的网络集成。它提出并讨论了一个通用的、时域的、资源到线路的模型，该模型可用于探索以下影响:增加设备数量、阵列大小和物理定位;以及控制参数的调整。三维波场被建模为非平稳的，具有从测量波高程时间序列中提取的统计特征，以模拟日益现实的海况。每个浮筒都有高压油动力起飞，机载储能，驱动双馈感应发电机(DFIGs)。利用该模型的仿真结果验证了储能对实际发电量的总体影响，以及虚功率控制对电网电压分布的影响。识别并讨论了改进网络集成的机会。
