Unmanned aerial vehicle power supply can be said to be the “heart” of electric unmanned aerial vehicles, and it is the fundamental support for the development of other systems of electric unmanned aerial vehicles.
The instantaneous starting power of the unmanned aerial vehicle starting power supply is above 10 °C, even reaching 20 and 30 °C. Power management technology. After the engine is started by the power supply, the engine drives the generator to run, and the generator and the battery pack are connected to the grid to charge the battery pack.

Using a more advanced method for particle swarm optimization, the combined wind power system’s scheduling model is resolved. Lastly, an example demonstrates the scheduling model of the combined wind power system’s viability. The joint operation system is shown in Fig. 1 [10, 11].
The pre-operation programming model of wind pumping and storage is built to eliminate wind power fluctuation and increase wind farm profitability depending on the predicted wind power and load data. Using a more advanced method for particle swarm optimization, the combined wind power system’s scheduling model is resolved.
Consequently, an efficient method of achieving wind power absorption and steady grid operation is the coupling and complementarity of wind energy on the power side of the equation . Currently, capacity construction and optimal scheduling are the two critical areas of study for wind storage power generation systems.
In the end, a control framework for large-scale battery energy storage systems jointly with thermal power units to participate in system frequency regulation is constructed, and the proposed frequency regulation strategy is studied and analyzed in the EPRI-36 node model.
Since the battery energy storage does not participate in the system frequency regulation directly, the task of frequency regulation of conventional thermal power units is aggravated, which weakens the ability of system frequency regulation.
The battery energy storage system (BESS) is a better option for enhancing the system frequency stability. This research suggests an improved frequency regulation scheme of the BESS to suppress the maximum frequency deviation and improve the maximum rate of change of the system frequency and the system frequency of the steady state.
The results of the study show that the proposed battery frequency regulation control strategies can quickly respond to system frequency changes at the beginning of grid system frequency fluctuations, which improves the stability of the new power system frequency including battery energy storage.
