    • A method for operating a power generation system coupled to a power grid during a grid unbalance event, a method for determining an injection current to be supplied into a power grid by a power generation system, and a method for addressing an asymmetric grid fault in a power grid connected to a power generation system are provided. The methods may be carried out based on a reactive or an active power/current priority. For reactive power/current priority, positive and negative sequence reactive currents are first determined and adjusted. Positive and negative sequence active currents are determined such that a maximum current limit, a maximum allowed active power ripple and a maximum grid side converter voltage are not exceeded. For active power/current priority, positive and negative sequence active currents are first determined. Positive and negative sequence reactive currents are then determined based on the positive and negative sequence active currents. The positive/negative sequence active/reactive currents are determined such that a maximum current limit, a maximum allowed active power ripple and a maximum grid side converter voltage are not exceeded.
    • 一种用于在电网不平衡事件期间操作耦合到电网的发电系统的方法,用于确定由发电系统供应到电网中的注入电流的方法,以及用于解决电力系统中不对称电网故障的方法 提供连接到发电系统的电网。 这些方法可以基于无功或有功功率/电流优先级进行。 对于无功功率/电流优先级,首先确定和调整正负序无功电流。 确定正序和负序有功电流,使得不超过最大电流限制,最大允许有功功率纹波和最大电网侧转换器电压。 对于有功功率/电流优先级,首先确定正序和负序有源电流。 然后基于正序和负序有源电流来确定正和负序无功电流。 确定正/负序有功/无功电流,使得不超过最大电流限制,最大允许有功功率纹波和最大电网侧转换器电压。
