new energy photovoltaic on grid solar power system technology
Welcome to the information network of solar photovoltaic power technology. Here, we provide information about photovoltaic cells, solar power system circuit topology and on grid solar system Inverter control strategy, etc.
Due to its simple structure and easy implementation, the perturbation observation method is currently one of the commonly used methods to implement MPPT. The principle is to increase or decrease the output voltage or current of the photovoltaic array at a certain interval of time, and observe the direction of power change thereafter to determine […]
The true maximum power point tracking method requires real-time measurement of voltage and current, and judges the changes in the operating point of the photovoltaic array through the voltage and current values, thereby realizing the optimization of the operating point. The advantage of this type of method is that it is not affected by factors […]
Since the PV characteristic of photovoltaic modules is a single-peak nonlinear curve, the maximum power point of the photovoltaic array composed of its series and parallel connections will also be affected by the light intensity and the surface temperature of the photovoltaic array. Therefore, how to track the maximum power point of the photovoltaic array […]
