The grid simulation device for photovoltaic power generation

Abstract

Solar photovoltaic power generation is the solar radiant energy directly into electricity method, namely the sun radiant energy by solar cells is converted into electrical energy, again through energy storage, control, and transformation, and into people’s dc or ac power that can be used directly. The so-called grid-connected network is simply said to be realized by using the principle of simultaneous operation of voltage, phase, phase sequence, and frequency. The simulation device of its inverter grid-connected is designed, the scheme of simulating grid-connected is given, the drive control system and filter system are designed, and the implementation scheme of the drive control system is introduced in detail. The design and parameter selection of the main circuit and the filter system are given in detail. The hardware and software implementation scheme and circuit structure of the system are given based on DSP. The entire system can meet the requirements of microgrid simulation operation.
