Simulation of wind power plants
The overall objective with the project has been to develop and verify a model for assessment of the interaction between a wind farm and the power systern.
The objective of the project is to develop and verify a model to assess the power plant characteristics of a wind farm. Power plant characteristics are understood as the influence on the stability of the power system, the ability to take part in the regulation, and the influence on the power quality. The model is intended bring more focus to the power plant characteristics in the development of wind turbines and electric ancillary equipment. Besides, the intention is to provide the wind turbine industry with a tool to verify these characteristics, enabling the industry to meet the requirements stated by the Danish system responsible and similar requirements on the international market. The working program of the project consists of the following elements: 1. Development of a model of the electric properties of the planned wind farm in Hagesholm, consisting of six 2MW NEG-Micon wind turbines. The model will consist of submodels for wind speed input, wind turbine dynamics and the power collection system of the wind farm. 2. Verification of the model, based on measurements in Hagesholm. 3. Assessment of the power plant properties of the wind farm, based on simulations with the wind farm model connected to model grids specified by Danish system responsible. The model is expected to be used by DanControl and NEG-Micon in the future development of wind turbines, park monitoring and control, and electric ancillary equipment. The general parts of the model are also expected to be used by other wind turbine manufacturers in development of similar models with their wind turbines
The developed model is intended to be used by the wind energy industry include the power system interaction in the design process of the wind turbine. It will provide the wind energy industry with a better understanding of the technical problems and challenges, and will contribute to the development of wind farms with better power plant characteristics, which will make the wind farms better suited for integration in the power systems. Also, the intension is to provide the wind energy industry with a tool to document the behavior of the wind farms towards costumers and utilities. The concrete objective of the project has been to develop a model for the wind farm in Hagesholm, Denmark. The Hagesholm wind farm consists of 6 active stall controlled 2 MW NEG-Micon wind turbines. The model is structured in submodels, which ensures a high degree of flexibility in reusing the models to model another wind farm. The models have been verified based on measurements in Hagesholm. For that purpose, a combination of WINDTEST measurements on the mechanical structure if turbine 1, power measurements on turbine 1 and 2 and meteorological measurements on a mast, and Risø power quality measurements on wind turbine 1 have been used. Besides, the park scale wind models have been verified using wind measurements form the Vindeby offshore wind farm site. Finally, the interaction between turbines and power system has been described, and a comparison between simulated and measured power quality, based on the definitions in IEC 61400-21
