“…In short, there is little research on this problem and no unified solution. In the dynamic regulation of the unit, the internal problem of the engine-generator set system is mainly speed adjustment [18], and the external problem is mainly the electric power response output to the bus [19][20][21]. Based on these two problems, this paper adopts the speed regulation method of the engine throttle opening to adjust the output power and the generator controller to adjust the speed to control the changes of electromagnetic torque reasonably and avoid the situation of engine overload or even car failure during the dynamic regulation process.…”

Ultralight power generation equipment has high requirements for the power density, continuous operation, and transient stability of the whole machine, and there is a direct conflict between high power density and substantial stability control in the power unit design. In order to meet the power density requirements of ultralight power stations, three main problems need to be solved, namely engine speed oscillation and flameout in the process of load power mutation, matching of the generator and engine torque, and stabilizing the voltage waveform of the AC output end. In this paper, we proposed an exquisite compound control strategy for ultralight power generation systems in engines, generators, and inverters. The effectiveness and practicability of the proposed strategy are verified by both simulation and experiment. The results show that the proposed control strategy can effectively solve the instability problem of the ultralight generator set and improve the stability of the system, where response recovery can be achieved within 0.9 s under the conditions of a total load increase or decrease, and the mismatching degree of the generator following the engine is reduced by 90%. The strategy could also guarantee long-term stable operation with high-quality electrical energy output.
