The models of TEM and PV including variation in temperature and temperature dependent parameters have been developed. Simulated results have conformed to the specifications of the considered commercial modules. The MPPT operation of individual developed model has been studied and compared with integrated PTH (PV+TEG) system to demonstrate close matching. The integrated system has been controlled under master-slave configuration with battery source operating as a Master for both PV and TEM. The voltage at point of common coupling is maintained by the battery. The performance of PTH system is evaluated for load perturbations and the variations in the solar insolation. The master slave control effectively handles the fluctuating power evacuated from both PV and TEG sources and complements the power from battery to cater the demand of perturbing load. Such hybrid system proposes a clean energy source by absorbing residual heat, unnecessarily accumulated on PV panel, thus enhancing conversion efficiency of PTH system largely when compared with the PV panel, presenting a huge power density per unit surface area suitable for roof top applications in metros. Hybrid system is applicable for all seasons and operates with approximately equal efficiency for both summer and winter seasons. The system can be deployed at any place with hot and cold climate conditions with matching efficiency. In the present work the considered system operates in standalone condition.
Future work is also planned to transform standalone PTH system to grid connected preposition for optimization of the efficiency. It is also proposed to develop appropriate power electronic switching circuit including auto changeover based on temperature and solar irradiation to cope with intermittent shedding condition and its effects on generation. Proposed solution will be effectively a breakthrough solution for optimization of efficiency of solar generation.
