Modeling of a hybrid marine current-hydrogen active power generation system

Adaptive hysteresis band current control(AHB CC) is used to control the three-phase grid currents by means of grid side converter in wind power generation system in this paper. AHB has reached the good purpose with PLL (Lock phase loop). First the mathematical models of each part are given. Then the control strategy of grid side converter-based wind power generation system is given in detail mainly including ABH CC and PI controllers of DC-link voltage, active power, reactive power. Finally the simulation model is set up which consists of power circuits, such as the grid side converter, LCL filter, transformer and grid, and control parts, etc. The simulation results have verified that the control strategy is feasible to fit for control of gird currents, active power, reactive power and DC-link voltage in wind power generation system.

Grid Side Converter

Virtual flux oriented direct power control (VFDPC) is combined space vector modulation (SVM) with PI of DC-link voltage, active power and reactive power to control the grid side converter in wind power generation system in this paper. VFDPC has reached good performances with PLL (phase lock loop). First the mathematical models of grid side converter, LCL filter and phase lock loop are given. Then the control strategy of grid side converter-based wind power generation system is given in detail. Finally the simulation model is modeled consisting of power circuits, such as the grid side converter, LCL filter, transformer grid, and control parts, such as PI controllers of DC-link voltage, active power, reactive power, and SVM, and so on. The simulation results have verified that the control strategy is feasible to fit for control of gird currents, active power, reactive power and DC-link voltage in wind power generation system.

The Impact

The impact of grid-connected photovoltaic power on power quality and reliability of power supply has gained more attention, with the continuous improvement of its generation capacity. This paper describes the power conditioning system of grid-connected photovoltaic power plants based on super-capacitor energy storage, which acts as the energy storage element to stabilize fluctuations in output active power of photovoltaic power generation system. Based on the configuration and principle of the power control system, a power and current double closed loop feedback hysteresis current control strategy is proposed in details, which controls the super capacitor energy storage system to absorb and complement the active power output fluctuations of the photovoltaic power generation system. The effectiveness and good operating performance of the device and control strategy are validated by simulation with PSCAD/ EMTDC.
