“…For small load, they tackle the change in load demand without changing in frequency for load frequency control system with demand-side control through the smart meter [4][5][6][7][8]. But small DG with gasifier plant was found to be effective in automatic shaking mechanism reducing the tar [9], adaptive predictive control for adjustment of oxygen concentration in syngas [10], performance control are done when the gasifier is unstable, robust optimal control for shell gasifier in LFC power plants [11][12][13][14][15][16], and solar farm was found controls technique battery storage [17], energy management unit and integrated control of photovoltaic (PV) solar farm [18][19][20], and PV solar farms feed active power during day time and become inactive in the night time [21][22]. Both, LFC systems help to reduce the demand for transmission by overcoming local and tie-line stability when control design appropriate for interconnected power systems [23][24].…”

Load frequency control (LFC) in interconnected power system of small distribution generation (DG) for reliability in distribution system. The main objective is to performance evaluation load frequency control of hybrid for interconnected two-area power systems. The simulation consist of solar farm 10 MW and gasifier plant 300 kW two-area in tie line. This impact LFC can be address as a problem on how to effectively utilize the total tie-line power flow at small DG. To performance evaluation and improve that defect of LFC, the power flow of two-areas LFC system have been carefully studied, such that, the power flow and power stability is partially LFC of small DG of hybrid for interconnected two-areas power systems. Namely, the controller and structural properties of the multi-areas LFC system are similar to the properties of hybrid for interconnected two-area LFC system. Inspired by the above properties, the controller that is propose to design some proportional-integral-derivative (PID) control laws for the two-areas LFC system successfully works out the aforementioned problem. The power system of renewable of solar farm and gasifier plant in interconnected distribution power system of area in tie – line have simulation parameter by PID controller. Simulation results showed that 3 types of the controller have deviation frequency about 0.025 Hz when tie-line load changed 1 MW and large disturbance respectively. From interconnected power system the steady state time respond is 5.2 seconds for non-controller system, 4.3 seconds for automatic voltage regulator (AVR) and 1.4 seconds for under controlled system at 0.01 per unit (p.u.) with PID controller. Therefore, the PID control has the better efficiency non-controller 28 % and AVR 15 %. The result of simulation in research to be interconnected distribution power system substation of area in tie - line control for little generate storage for grid connected at better efficiency and optimization of renewable for hybrid. It can be conclude that this study can use for applying to the distribution power system to increase efficiency and power system stability of area in tie – line.

“…This isolation is provided by the intermediate DC/DC stage. A Dual Active Bridge (DAB) DC/DC converter is commonly used for this role as proposed by many recent works [14]- [16]. However, in most of the works, the required isolation is not a major issue in the design mainly due to the application of interest.…”

This paper analyzes the design and construction of a SiC-based Dual Active Bridge (DAB) converter for its use in a three-stage Power Electronic Transformer (PET) based on a Modular Multilevel Converter (MMC). The galvanic isolation between primary and secondary of the PET provided by the DAB High Frequency Transformer (HFT) is 24 kV. Challenges for the HFT design are discussed. A 5 kW DAB prototype using commercial 1.2-kV SiC MOSFETs is built to confirm the correctness of the design process. Parallelization of the DAB HFT to increase the power being transferred is also discussed.
