This invention discloses a method, device, electronic equipment, and storage medium for real-time reactive power control in distribution networks based on co-simulation, belonging to the field of smart distribution network operation control. The method includes: acquiring real-time active power values ​​of each photovoltaic inverter in the distribution network, as well as real-time active load values ​​and real-time reactive load values ​​of each load node; generating an initial population containing multiple sets of reactive power control vectors based on the real-time active power values; determining a target reactive power control vector from the initial population through iterative optimization, and controlling each photovoltaic inverter to adjust its power according to the target reactive power control vector. By implementing this invention, the problems of cumbersome modeling and difficulty in adapting to complex distribution network topology changes caused by relying on the construction of explicit mathematical models in existing technologies, and difficulties in convergence or even no solution in optimization under severe source-load fluctuations due to the use of hard voltage constraints, can be solved.

According to one embodiment, the power amplifier includes a plurality of switches and an output tank network. One or more of the plurality of switches are configured to generate one or more first intermediate waveforms having one or more first fundamental frequency components, and one or more of the plurality of switches are configured to generate one or more second intermediate waveforms by chopping one or more of the first intermediate waveforms at a controllable timing. The second intermediate waveforms have one or more second fundamental frequency components that are controllably reduced from the fundamental frequency components of one or more first intermediate waveforms. The output tank network is configured to filter one or more second intermediate waveforms to provide an output waveform having one or more third fundamental frequency components to the load. In some cases, all switches achieve zero-volt switching under different power and load conditions with resistive and reactive loads.
