A model-free MADDPG algorithm with centralized training and distributed execution framework is applied to learn the optimal reactive power generation strategy for PV inverters. In addition, we measure the violations of physical principles (here is voltage deviation) in the neural network outputs to improve training stability.
Therefore, the PV generation and electricity demand variation profiles are generated, i.e., P t PV + rand (σ PV) and P t L + rand (σ L). 100 randomly generated scenarios are chosen for testing, and the proposed method is run on them. The voltages at bus 13 in 33-bus and 141-bus networks under 100 random scenarios are presented in Fig. 13.
