Outline
Bifacial photovoltaic modules are designed to generate electricity by absorbing both front and rear irradiance at the same time, which enhances the power generation compared to monofacial photovoltaic modules. In this paper, a twomode power control strategy is proposed based on bifacial photovoltaic modules. Firstly, the modified equivalent irradiation model is used to construct a parametric model of the electrical characteristics of bifacial photovoltaic modules; according to the power output characteristics of bifacial photovoltaic modules and then based on the judgement of irradiance, a twomode control strategy with the maximum power output and the power reserve control is proposed; finally, the model is used to experiment and simulate the 365 W crystalline silicon bifacial photovoltaic module. The experimental results show that the relative error between the predicted power and the measured power is less than 3.5%, and the relative error of the voltage at the maximum power point under the measured condition is 0.3%. The twomode power control strategy can achieve the realtime active power reserve without increasing the energy storage, in which the maximum active standby capacity at the transient equivalent irradiance of 1006 W/m² is 69 W, and at the transient equivalent irradiance of 1031 W/m² is 78 W.
