Abstract
The power dispatch strategy for onshore wind farms generally focuses on maximizing the captured power or minimizing the investment cost. However, as for onshore wind farms, there are some environmental impacts that need to be considered if needed. Among them, the wind turbine (WT) noise is a fairly obvious environmental impact. Noise caused by wind farms may cause interference to the surrounding living environment and the power dispatch strategy should combine power production and environmental factors. Besides, the amount of electricity generated by onshore wind farms is also affected by topography and power losses. In this paper, an optimal power dispatch strategy of wind farms with limited WTs noise impact is proposed for a better environmental performance as well as maximizing the power generation. The new method is compared with the traditional MPPT method for single WT and the improved global MPPT method for the whole wind farm within two terrain scenarios. The case results show the feasibility and effectiveness of this novel strategy.
