Power management strategies play a key role in the design process of hybrid electric vehicles. Electric Assist Control Strategy (EACS) is one of the popular power management strategies for hybrid electric vehicles (HEVs). The present investigation proposes a new framework to advance the EACS. Dynamic Programming method is applied to an HEV model in several drive cycles, and as a result, some op...

Computer virus attacks result in significant losses each year, drawing considerable attention from enterprises, governments, academic institutions, and various other sectors. Researchers have proposed approaches to fight against computer viruses, including antivirus software internet firewalls. In this paper, we focus on investigating transmission the perspective of mathematical modeling. Our m...

in this paper a comprehensive approach is presented to improve power swings damping based on direct lyapunov method. the approach combines superconducting magnetic energy storage (smes) system with static synchronous compensator (statcom). considering the energy absorption/injection ability of smes, in transient states the combination exchanges both active and reactive powers with power system....

Decentralized control strategies are popular candidates in microgrids control because of their reliability and performance. Conventionally, droop control (as a main decentralized strategy) is been utilized in order to prevent permanent droop of voltage and frequency after change in loads and also to share generated power between distributed generation units. In this paper, a new droop control s...

As a large number of converters composed power electronic devices are connected to the grid, system has gradually decreased stability. How increase dynamic response converter become one research hotspots. Virtual synchronous generator technology (VSG) can endow with moment inertia and damping characteristics, thereby enhancing response, but traditional VSG cannot achieve optimal control effect....
