Requirements and capabilities of power electronic interfaced devices for enhancing system operation
The worldwide energy landscape is undergoing a transition, the pace of which varies in different parts of the world. From system operation perspective, the main factors identified contributing to this ongoing energy transition are threefold. Firstly, the transmission system connected conventional synchronous generator is rapidly being replaced by transmission system and distribution system connected variable renewable energy sources (RES) such as wind and solar generation, which are usually connected through power electronics converters. Secondly, the design, planning, and operation of the power system is largely influenced by different regulatory regimes. Thirdly, it is increasingly difficult to construct new transmission facilities, on the one hand due to increasing public opposition against new overhead lines and on the other hand due to technical challenges associated with long AC underground cables. Taking these observations into account, the transition of the energy landscape poses important operational challenges for System Operators: how should the future power electronis-dominated power system be operated at an affordable cost, while guaranteeing at least the same level of operational reliability as today?
