Abstract
A solar energy conversion system feeding to a single-phase utility grid employing SPWM-based dq control has been employed for autonomous control of real and reactive power. The controller consists of a dc-dc boost converter and a voltage source inverter (VSI). In addition to feeding power to the grid, the scheme in this chapter also supplies a local RL load. It is ensured that reactive power of load is supplied from VSI, in order to maintain unity power factor (UPF) at grid terminals. A PI controller is used for varying the duty ratio of the dc-dc converter to maintain the dc link voltage constant. The grid synchronization of VSI is achieved through phase-locked loop (PLL). To evaluate the performance of this scheme, MATLAB/Simulink-based model is tested under varying irradiations. Experiments have been carried out on a PV array of 480 W, 130.8 V, 4.5 A, and the test results are furnished to validate the developed scheme. The controllers used are implemented using dSPACE DS1103 controller.
