Research on the High Voltage DC Grid-Connected Converter Based on Photovoltaic

Abstract:

With the rapid development of the VSC-HVDC Power transmission and distribution grid demonstration projects, the technology of the DC transmission once again becomes a research focus. In order to meet the needs of accessing VSC-HVDC power grid of Photovoltaic power generation, the topologies suitable for photovoltaic high voltage DC grid-connected converter was analyzed, the program based on the dual-module combination of full-bridge topology structure was proposed, a detailed control strategy using dual-loop of voltage and current loops was given, and finally a 12kW simulation model to verifying the system topology and control strategy was constructed using PSIM. The simulation results show that the PV high voltage DC grid-connected converter has a good dynamic response and steady state performance.
