PSO-based Model and Analysis of Photovoltaic Module Characteristics in Snowy Conditions

This paper proposes a new model for photovoltaic panels to represent the electrical characteristics when the module are covered in snow. The penetration of solar radiation in snow is estimated using the theory developed by Giddings and LaChapelle and implemented with a particle swarm optimisation to determine the electrical parameters of the PV module in the presence of snow. The characterisation of 3 photovoltaic modules obtained from the simulation of the proposed model has been confirmed by experimental results under various climate conditions. The predicted power output of the model has been also further validate by SCADA measurements on a 12-MW grid-connected PV farm. This study is particularly useful for the accurate prediction of snow-related reduction of the power generated by photovoltaic modules, thus reducing the uncertainty on the level of generation from the renewable sources mix during cold months. - Pietro Tricoli, Deputy Editor in Chief

Refined ramp event characterisation for wind power ramp control using energy storage system

This paper analyses how energy storage can effectively support wind turbines during wind power ramp event. The power ramp events are characterised into only 4 scenarios, obtained from the wind power ramping trends and the state of charge of the energy storage, thus simplifying significantly the control algorithm in comparison with the exiting literature. For each ramp power scenario, the state of charge of the energy storage is kept within the defined operational range by an adjustment strategy that takes into account the level of wind power generation and the parameters of energy storage. The paper demonstrates that with the proposed adjustment strategy there is less curtailment of wind power generation during power ramp events even in case of uncertainty of wind conditions. Simulation results using real wind data have confirmed the suitability of the proposed method and the better performance in comparison to methods based on rate limiters or low-pass filters. This study would be then useful for all the application where significant wind variations cause a saturation of the generation capacity of the wind farm and could also potentially lead to the instability of the system. - Pietro Tricoli, Deputy Editor in Chief

Study on speed and torque control of a novel hydromechanical hybrid transmission system in wind turbine

The paper analyses a new hydromechanical transmission system for wind turbines to overcome the limited reliability of traditional mechanical gear systems. In the proposed transmission system, a power splitter based on a parallel shaft gear sends part of the power directly to the electrical generator via a planetary gear, and the rest to a hydraulic pump. The hydraulic power is then transmitted to the electrical generator through the same planetary gear. The paper demonstrates with a mathematical analysis that the hydraulic system can effectively absorb torque fluctuations, while keeping the average power to a value significantly smaller than that transmitted mechanically, thereby guaranteeing a high efficiency of the transmission. Experimental results on a 30 kW lab prototype provided evidence that the proposed transmission system ensures speed control below the rated wind speed and torque control above the rated wind speed. The important potential impact of this paper is the higher reliability of the transmission system achieved by the reduced torque stresses on the mechanical gearbox, which would in turn reduce the number of failure of wind turbines and, ultimately, the maintenance costs. - Pietro Tricoli, Deputy Editor in Chief
