Renewable energy, particularly solar photovoltaic power integrated with hydropower, has become a remedy for replacing conventional electricity to provide important opportunities for the safety utilization of electric power. However, the solar photovoltaic power is intermittent and stochastic due to the uncertain solar irradiance, which can lead to the unstable operation of the complementary power system. For this consideration, this paper focuses on the stability mechanism of the hydropower regulation responding to the volatility of solar photovoltaic power. To achieve the analysis, a hydro-PV hybrid power system is established. Then, the effect of the hydropower regulation on dynamic stability of a hydro-photovoltaic hybrid system is investigated considering two hydropower regulation factors such as the optimization of hydropower control parameters and the performance of dynamic hydro regulation indicators. Finally, the optimized proportional, integral and derivative adjustment parameters are obtained, and the dynamic rule of regulation indicators responding to the volatility of photovoltaic power is also revealed. The obtained results not only help make an optimal decision for the coordinated operation of renewable-based power systems, but also benefit for the reduction of the operational cost and power curtailment.
