The large-scale integration of photovoltaic generation increases the difficulty of maintaining secure and stable power system operation because solar output changes rapidly and is difficult to predict accurately. In cascade hydropower – photovoltaic systems, hydropower units can provide flexible regulation, but a dispa...

To address inaccuracies in reactive power optimization caused by the absence of integrated distributed photovoltaic (PV) in active distribution network (ADN), this paper proposes a Transformer-based PV capacity estimation and reactive power optimization method for ADN with limited information. The self-attention mechan...

With the increasing penetration of photovoltaic (PV) generation, the uncertainty and intermittency of PV output pose significant challenges to renewable energy accommodation and secure power system operation. To improve the utilization of renewables in cascade hydropower (CHP)-PV complementary systems, this paper propo...
