Operation efficiency is one of important concerns for power conversion system. Efficiency issue microgrids with multiple paralleled inverters has been paid slightly concerns. Therefore, this article presents an analysis method microgrid in system level and efficiency-prioritized droop control strategy to improve operation under different load profiles. model first established reveal time-varyin...

Modern power systems require increasing intelligence and flexibility in the control and optimization to ensure the capability of maintaining balance between generation and load under violent disturbances. There are several inverter interfaced distributed generations (IIDGs) with local and global control loops in a microgrid (MG). Voltage and frequency of MGs are strongly impressionable from the...

We investigate the design of future energy storage systems by exploring one particular solution, in simulations. We use Lithium-ion batteries for storage, a dual active bridge (DAB) for DC to DC conversion and a synchronverter to transfer energy from the DC bus to the utility grid. We show how some recent improvements to the synchronverter algorithm can be combined with a battery management alg...

Biomass is identified as one of the major renewable energy sources for electrical power generation. Heavy duty gas turbine engines are preferred for clean and efficient power generation. An extensive literature survey reveals that the governor droop setting of the heavy duty gas turbines varies from 2 percentage to 10 percentage. But it needs to be optimized for analyzing the dynamic response o...

Efficiency droop in GaN-based light emitting diodes (LEDs) under high injection current density perplexes the development of high-power solid-state lighting. Although the relevant study has lasted for about 10 years, its mechanism is still not thoroughly clear, and consequently its solution is also unsatisfactory up to now. Some emerging applications, e.g., high-speed visible light communicatio...
