A photovoltaic model based matched load operation mode for power plants of nanosatellite

الملخص EN

The mode of matched load is the most effective mode that provides a maximum output power of power plants of nanosatellite.

Therefore, it must be designed to be efficient and reliable to harvest the required power.

There are two main operating scenarios of a nanosatellite in space, the first when the nanosatellite is stabilized with its photovoltaic (PV) array pointing to the sun and the second is when the nanosatellite experiences rotation and each PV array will face the sun for a short period.

The rotation causes the satellite PV to face the sun at different angles which constantly change solar insolation level and temperature.

In this work is achieved by introducing a method for tracking the maximum power point of photovoltaic panels with the help of a power coefficient for tracking the position of maximum power area and the next using one of the known direct of modified hill climbing.

The proposed method allows increasing the average installed capacity utilization factor up to (36% -40% ) of nanosatellite photovoltaic power plant.
