The design of reliable controllers for wind energy conversion systems (WECSs) requires a dynamic model and accurate parameters of the wind generator. In this paper, a dynamic model and the parameter measurement and control of a direct-drive variable-speed WECS with a permanent magnet synchronous generator (PMSG) are presented. An experimental method is developed for measuring the key parameters of the PMSG. The measured parameters are used in the design of the controllers. The generator-side converter is controlled using a vector control scheme that maximizes the power extraction under varying wind speeds. A model predictive controller (MPC) is designed for the grid-side voltage source converter (VSC) to regulate the active and reactive power flows to the power grid by controlling the d-and q-axis currents in the synchronous reference frame. The MPC predicts the future values of the control variables and takes control actions based on the minimum value of the cost functions. To comply with the grid code requirement, a modified design approach for an LCL filter is presented and incorporated into the system. The design process is simple and incorporates significant filter parameters while avoiding iterative calculations. The comparative analysis of the designed filter with conventional L, LC, and iterative LCL filters demonstrates the effectiveness of the modified design approach. The proposed wind energy system with MPC and LCL filter is simulated in MATLAB/Simulink and experimentally implemented in the laboratory using the dSpace digital signal processor (DSP) system. The simulation and experimental results validate the efficacy of the designed controllers using the measured parameters and show dynamic and steady-state performance under varying wind speeds. Index Terms--Wind energy, permanent magnet synchronous generator (PMSG), parameter measurement, model predictive controller (MPC), LCL filter.

Algoritmos de rastreio do ponto de máxima potência (Maximum Power Point Tracking -MPPT), associados a conversores bidirecionais (back-to-back) e geradores síncronos de imã permanente (Permanent Magnet Synchronous Generator -PMSG), são vastamente utilizados para extrair a máxima potência de sistemas eólicos (Wind Energy Conversion System -WECS) de velocidade variável. Neste trabalho são avaliados e comparados diversos métodos comumente utilizados em sistemas eólicos, indicando vantagens e desvantagens. Esses métodos apresentam diversos pontos que dificultam sua utilização em sistemas de baixa potência. As simulações apresentadas neste trabalho indicam que o método do controle adaptativo e a sua modificação são ótimas alternativas a serem aplicadas, visto que são algoritmos perfeitamente adaptáveis as mudanças climáticas e não necessitam de sensores de medição do vento e nem do conhecimento dos parâmetros do sistema.

“…Full-scale voltage source converter (VSC) based back-to-back configuration is the most promising converter topology for the grid integrated wind power system (WPS). Advanced control methodologies for high-performance operation, automated real and reactive power control, independent control of voltage and power regulation and reduced necessities for harmonic filtering are the advantages offered by this topology (Bakhtiari and Nazarzadeh, 2020; Hackl et al, 2019; Muyeen et al, 2010; Nasiri and Mohammadi, 2017). Intellectual control of the back-to-back converter maximizes the captured wind power, as well as fulfils the requirements imposed by the utility operators.…”

This paper presents a direct analytical method to predetermine the steady-state values of a permanent magnet synchronous generator (PMSG) based wind power system (WPS) at each stage of power flow. A generalized structured is developed with two independent equivalent circuits, that is, PMSG and grid side. To effectively determine the converters performance numerals despite grid disturbances, steady-state model is structured with positive sequence components of grid voltage. The advantage of the proposed model is that the methods evade the requirements of d-q modeling and a dedicated controller to evaluate the system performance. Using the proposed steady-state model, the entire WPS components ratings is predicted evading time domain simulation with complicated controller design. Also, the simple controller design is proposed to aid in optimal power flow supplement with FRT requirements under all possible system operating conditions. Ultimately, validation of predetermined values with the simulated PSCAD/EMTDC response including the proposed controller is investigated.
