In this paper, a multiagent system-based protection and control scheme is proposed to deal with diverse operation conditions in distribution system due distributed-generation (DG) integration. Based on cooperation between DG controller relays, an adaptive algorithm designed converter-based wind turbine limit the influence of infeed fault current. With consideration modes, relay setting strategy developed help protective relays adapt suitable settings different caused by variations topology...
With the increasing integration into power grids, wind plants play an important role in system. Many requirements for have been proposed grid codes. According to these codes, should ability perform voltage control and reactive compensation at point of common coupling (PCC). Besides shunt flexible alternating current transmission system (FACTS) devices such as static var compensator (SVC) synchronous (STATCOM), turbine itself can also provide a certain amount compensation, depending on speed...
Taiwan is not large in area, but it has a complex geological structure due to intense orogeny. From east west, can be divided into five major zones: the Coastal Range, Central Hsuehshan Western Foothills, and Plain. The southwestern region of primarily comprises Foothills belong foreland western orogen. During Oligocene, rifting South China Sea led development several east-west-oriented normal faults. Subsequently, late Quaternary, northwestward compression Philippine Plate caused series...
With the increasing integration of wind power into system, farm are required to be controlled as a single unit and have all same control tasks conventional plants. The central controller receives orders from Transmission System Operator (TSO), then dispatch reference each turbine. One most commonly used methods is turbine proportional turbine's available without consideration wake effect. which depends on thrust efficient upstream turbines in influences downstream speed determines Optimize...
Since large-scale wind farms are increasingly connected to modern power grids, the transmission system operators put more requirements as part of grid codes on integration farms. System frequency control which is normally provided by conventional synchronous generators becomes a common requirement This ancillary could have some influence small signal stability. paper implements an strategy direct-drive-full-convertor-based farm and studies its damping ratio values dominant oscillation modes...
As a common tendency, large-scale wind farms are increasingly connected to the transmission system of modern power grids. This introduces some new challenges systems, and operators (TSOs) have put requirements as part grid codes on integration farms. One requirement is function voltage control which can be implemented in grid-side convertor controller variable speed turbine. ancillary provided by could influence small signal stability. paper implements an strategy...
With the increasing size of wind farms, impact wake effect on energy yields and lifetime consumption turbine can no longer be neglected. In this paper, affecting factors like speed direction are investigated in terms single multiple wakes. As power converter is most fragile component among system, its estimation calculated seen from thermal stress semiconductor. On basis relationship a 5 MW Doubly-Fed Induction Generator (DFIG) system speed, individual 10-turbine an 80-turbine farms by...
