“…Recently, it has been reported that the hybrid solar-thermal system and biogas turbine (BGT) can generate electricity at an efficiency of 26.95%, which is higher that of the individual efficiencies. 10 Such hybrid system utilizes the solar energy as a heat source to enhance the temperature of the biogas prior to combustion and hence improve the efficiency. However, solar thermal-BGT has been yet reported in the erection of hμGs and related studies.…”

A proficient frequency regulation scheme has been explored in this work for two interconnected hybrid microgrids (hμGs) comprised of multiple renewable energy sources, like solar-thermal units, wind turbine generator units, solar photovoltaic, biogas turbine, biodiesel generator, and storage units. A new optimization algorithm has been formulated to replicate the photo-tactic swarming behavior of green leafhoppers named Green Leaf-hopper Flame optimization algorithm (GLFOA) to tune the system controllers (proportional integral (PI)/proportional derivative (PD)/proportional integral derivative (PID) controllers). The superiority of GLFOA is confirmed by comparing the performance with several popular optimization algorithms. To assess the stability of the hμGs several rigorous tests have been conducted considering availability/nonavailability of renewable resources, gusty wind, real-time variation of solar radiation and wind velocities along with the random load disturbances. GLFOA tuned PID controllers were found to be the best to contain the frequency deviations. The maximum peak overshoot, undershoot, and settling time obtained by GLFOA tuned PID controllers are 0.01051 Hz, À0.00764 Hz, and 14.15 s, respectively, which are within an acceptable limit. Further, there is an improvement of 0.15% in the performance index obtained by GLFOA over its counterpart obtained by grey wolf optimization, confirming the superiority of the GLFOA tuned controller.

“…Bustamante et al [9] conducted a detailed technical analysis of small-scale solar-biohybrid power generation systems using Rankine (steam turbine) and Brayton (gas turbine) cycles. Thermodynamic models were developed to characterize the state of working fluid and select the most suitable solar collection technology for individual power generation systems.…”
