“…The advantages of using the emulator instead of actual components are commonly small in size, highly efficient, lower in cost, safer alternative, easy to configure, and able to repeat the condition of the test. These emulators include the PV emulator [9], [10], wind turbine emulator [11], battery emulator [12], and load emulator (also known as electronic load) [13]. Nonetheless, the research conducted on the TEG emulator (TEGE) is still in the early stage.…”

Thermoelectric generator (TEG) can directly convert heat energy into electrical energy. It improves the power efficiency of the energy generation system by converting the power loss in the form of heat produced during the generation process into additional electrical energy. The TEG emulator (TEGE) is a power converter that produces a similar current-voltage characteristic as the TEG. It is a valuable device used to develop and test the TEG-based energy generation system. Nonetheless, the research on the TEGE is still in the early stage. This paper proposed a proper, low-cost, and high-efficient TEGE design using the buck converter. The contribution of the paper covers the TEG model in the form of an array, the buck converter design tailored to the TEGE, and 4 new control strategies proposed for the TEGE. The control strategies are the direct referencing method (DRM), perturb and observed (PnO) method, resistance comparison method (RCM), and resistance feedback method (RFM). The conventional proportional-integral controller is used to maintain a smooth operation during transient and steady-state periods. The results show the merits or demerits for each proposed control strategy based on the accuracy, transient response, stability, overshoot, and efficiency.

<span lang="EN-US">Energy storage plays an important role in the future of the power system. There are a lot of energy storage system (ESS) available and thermal energy storage shows a promising future. Conventionally, this system is based on a steam generator that converts heat energy to electrical energy and an electrical heater to convert electrical energy to heat energy. Nonetheless, there is still no proper ESS based on the thermoelectric generator (TEG), which can convert directly heat energy to electrical energy and vice versa. This paper proposed a power converter with a new controller for the thermal ESS based on the TEG. The bidirectional converter and the modified perturb and observe method are used to manage the energy transfer at the TEG. The thermal energy storage is based on the sensible approach, where the heat energy causes the temperature to increase. The results show that the thermal ESS based on the TEG is feasible since the energy can be stored and released from the proposed system.</span>

“…They are used both for AC (single and 3-phase) and DC characterizations of power converters, sources, and buses (Serban et al, 2006;Tsang and Chan, 2012;Peng et al, 2016;Geng et al, 2018;Kanadhiya and Bohra, 2018;Nujithra and Premarathne, 2018;Pudur and Srivastava, 2018;Serna-Montoya et al, 2019;Serna-Motoya et al, 2022). Typically, the ALs topologies for micro and nano grids are based on converters such as boost (Ayop et al, 2021), SEPIC (Vogman andConsulting, 2018), buck-boost (Meng-Ting et al, 2017), back-to-back (Li et al, 2008), and multilevel inverters (Niu et al, 2021).…”

The increased use of DC renewable energy resources and DC storage systems, combined with the necessary reduction of energy waste, is boosting the development of DC smart grids. In this scenario, DC load emulation is of great importance. From the hardware point of view, DC buses stability of smart grids and the different DC/DC converter topologies must be tested. From the software point of view, smart grid strategies and job schedulers must be tested with different power absorption profiles. Moreover, DC load emulation can be useful for many other purposes, such as battery characterization, power supply testing, photovoltaic I-V curve measurements, etc. In this work, a cost-efficient DC Active Load (AL) solution is proposed. The principle of the circuit topology is a buck-boost-derived converter. This solution can be designed and tested considering the required voltage, current, and maximum input power. Both simulation and experimental results are shown on a 400 W size prototype. Thermal and electrical results validate the simulation model and the AL feasibility.
