Research of Increasing Wind Turbines Penetration Based on PV Inverter Control Schemes

为了促进可再生能源的协调利用,基于主动配网管理的分布式电源控制研究成为可再生能源研究的热点之一。以利用光伏变流器的无功输出能力提高风机渗透率为主要目标,根据光伏阵列的有功功率、逆变器的大小和所需的无功功率设置,提出了不同类型的光伏变流器控制方案,并且确定了主动配网规划方案的目标函数和约束条件。将新的主动配网规划方案应用于一个含可再生能源的典型的10 kV主动配网系统,仿真结果表明,该方案可显著提高风电的渗透率。

The distribution network planning based on active network management （ANM） schemes has become one of hot topics in promoting coordinated utilization of renewable energy. The main target of this paper is increasing penetration of wind turbines by using reactive power output ability of PV inverter. According to the active power of photovoltaic arrays, the size of the inverter and the desired reactive power settings, several PV inverter control （PVIC） schemes are proposed with constraint conditions and objective function confirmed. In this study, the PVIC schemes are applied to maximize the total wind-distributed generation penetration on a typical 10 kV active distribution system. The simulation results show that the proposed schemes can significantly increase the wind penetration level.
