This paper addresses the new method of controlling wind turbine connected to the grid and presents the approach for implementing wind energy as a distributed generation in a power system. With the aid of a fuzzy controller that regulates the modulation index of PWM inverter in an AC-DC-AC converter, and controllable battery storage connected to DC Bus, output of voltage even during changing wind speed...
There were many accidents of large-scale wind turbines disconnecting from power grid in 2011. Single-phase-to-ground fault cannot be correctly detected. Single-phase-to-ground evolved to phase-to-phase fault. Phase-to-phase fault was isolated slowly, which led to low voltage. And wind turbines without enough low voltage ride-through capacity disconnected from the grid. After some wind turbines disconnected...
In this paper, the impacts of DERs on the designed SPSs are investigated and some solutions based on the progressively developing communication infrastructure of the newly evolving smart grids are proposed to maintain the integrity of the power system in extreme contingencies. A sample system with high penetration of DERs is considered and a SPS is designed for the system. Afterwards the impact of...
Future power systems face several challenges; one of them is the use of high power converters that decouple new energy sources from the AC power grid. This decreases the total system inertia affecting its ability to overcome system frequency's disturbances. The wind power industry has created a controller to enable inertial response on wind turbines generators: Artificial, Emulated, Simulated, or...
