Optimized Predictive Power Control of PMSG with Horizon Disturbance Observer

This paper proposes an improved predictive control strategy for permanent magnet synchronous generators with disturbance compensation. Traditional power predictive control strategies, due to the limitations in the number of converter levels, they exhibit significant steady-state error fluctuations, affecting the stability of the load-side bus voltage. This paper introduces an optimized switching sequence predictive power control strategy based on the synthesis of multiple vectors. By utilizing the synthesis of multi-vector voltages and optimization of switching sequences, fluctuations in bus voltage are reduced. The operating parameters of PMSG are prone to change, and disturbances occur during the operation of the generation system, further affecting the quality of electrical energy on the load side. To address these issues, this paper uses a rolling horizon observer to observe and compensate for disturbances within the predictive power control strategy. Simulation and experimental results verify the feasibility and effectiveness of the strategy proposed in this paper.
