A dynamic wind farm aggregate model for the simulation of power fluctuations due to wind turbulence

摘要: Abstract An important aspect related to wind energy integration into the electrical power system is fluctuation of generated due stochastic variations speed across area where turbines are installed. Simulation models useful tools evaluate impact on stability and quality. Aggregate reduce simulation time required by detailed dynamic multiturbine systems. In this paper, a new behavioral model representing aggregate contribution several variable-speed-pitch-controlled introduced. It particularly suitable for short term fluctuations turbulence, steady-state not applicable. The relies output rescaling single turbine model. divided its steady state components, which then multiplied different scaling factors. smoothing effect incoherence at locations inside farm taken account filtering curve means Gaussian filter as well applying proper damping part. has been developed be one building-blocks large system, therefore significant reduction pursued. Comparison against full obtained repeating model, shows that trade-off between accuracy computational achieved.
