An Aggregated Modeling Method Based on Frequency Response for Fixed Speed Wind Farms Navid Shabanikia n shabanikia@ec iut ac ir August 2017 Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Dr Ahmadreza Tabesh a tabesh@cc iut ac irAbstractWith increasing the penetration level of renewable energy resources in power systems impacts of these re sources in steady state and dynamic analysis of power systems interest engineers and researchers in the field ofpower engineering Currently wind energy in terms of installed capacity is the dominant source of renewableenergies Wind farms use a modular structure that include ample of wind turbine generators WTGs which areconnected to a grid Using detailed model for each WTG unit will provide a complex dynamic model for a windfarm with hundreds of WTGs Conventional method for modeling and analysis of a wind farm is to define anaggregated model that includes one or a few equivalent WTG units for different zones in the wind farm Thisthesis deals with developing aggregated model for analysis of wind farms with fixed speed WTGs The thesis presents a method for developing an aggregated model of a wind farm useful for the steady state and dynamic analyses To this end firstly the existing method for developing the aggregated modelsare investigated and their accuracy and performance in a dynamic analysis are investigated using a few testsystems Then a modelling method based on weighted summation of the frequency response of the all WTGsis suggested which provide an aggregated model for a wind farm The proposed method uses the dynamic modelof the generators in the synchronous reference frame to develop the model of WTGs in a wind farm Then theequivalent model of the wind farm is obtained using the model of each WTGs considering its participationto generate total wind power as a weighting factor to develop the aggregated model It is assumed that theaggregated model of the wind farm is similar to that of a single WTG in which the equivalent parameters of themodel are obtained based on the best matching of the frequency response of the wind farm with the proposedmodel Similarly an equivalent turbine for the mechanical parts of the WTGs is presented by defining the impactfactors of WTGs at a given operating point To evaluate the performance and accuracy of the proposed method a test system with two wind turbine generators is used under four different test conditions Then its aggregatedmodel is obtained using the existing and proposed methods Then the steady state and dynamic behaviors ofthe test wind farm system is simulated under different test conditions and the test results are compared withthose of obtained based on the conventional and the proposed aggregated models It is shown that the proposedmethod especially when the wind speeds and the parameters of WTGs in a wind farm are different providesmore accurate test results compared with existing methods where its error is less than 0 75 in the steady stateand 2 75 in transient tests
