Abstract
Thermoelectric generators (TEGs) convert heat energy into electrical energy depending upon the temperature difference across them and the applied electrical load. It is important to track the peak electrical operating point using power electronic converters which are controlled by a maximum power point tracking (MPPT) algorithm. Having linear electrical characteristics, fractional Open circuit voltage algorithm method is the optimum choice for obtaining it. This paper presents an effective way to perform the open-circuit voltage measurement of TEG during the pseudonormal operation of the interfacing power electronic converter and a design of grid connected TEGs where Voltage Source Converter (VSC) is controlled by Synchronous Reference Frame (SRF) detection and Hysteresis Current control thereby achieving control of Real power & Reactive Power for the GRID synchronism. This paper is modeled in PSCAD.
