摘要

This chapter introduces a unit template control algorithm that uses less number of sensors as compared to various control algorithms of variable frequency control (VFC) off-grid asynchronous generators (IAG). The IAG is run by an uncontrolled hydro turbine for power generation integrated with a solar photovoltaic PV system with consumer loads. Solar PV system consists of a DC-DC converter, and solar panels with a maximum power point tracking (MPPT) controller. The VFC with a four-leg IGBT converter and storage battery on a DC link with a connected point of common coupling (PCC). The four-leg IGBT converter is utilized for suppressing neutral current. The solar PV panels with DC-DC converter operating with MPPT algorithm charged battery on DC link of VFC. The control algorithm computes reference source currents swiftly based on controller gains. Unit templates require less execution and delay time of reference source currents. The proposed system is modeled and simulated in MATLAB/Simulink using the Simpower system toolbox. The simulation results show an off-grid asynchronous generator with a solar PV system performs neutral current compensation, harmonics diminution, load balancing, frequency, and voltage control.
