Microgrid is one of new conceptual power systems for smooth installation of many distributed generations (DGs), loads and energy storage system (ESS). The microgrid can operate both in grid-connected and islanded operation mode. The balance between supply and demand of power is one of the most importance means of improving energy efficiency. This paper presents a discussion on the management and control...
This paper discusses three power system topologies that are capable of handling regenerative power in EMA loads for more electric aircraft (MEA). A simple power system including a synchronous generator, an electromechanical actuator (EMA) and an electric accumulator unit (EAU) is builtto show the effectiveness of regenerative power management using EAU.
We have shown that an electronically controlled Energy Storage System (ESS), co-located with the main power source in a ship MVAC power system, can be used to absorb part of the fault current so that protective equipment can operate at reduced stress thus prolonging their life and increasing the reliability of the devices. Analysis and simulation results show that the method effectively reduces fault...
The wind energy generation, utilization and its grid penetration in electrical grid is increasing world wide. The wind generated power is always fluctuating due to its time varying nature and causing stability problem. This weak interconnection of wind generating source in the electrical network affect the power quality and reliability. The localized energy storages shall compensate the fluctuating...
This paper describes a method to enhance the load frequency control in a power system with distributed generations (DG). In this paper, a power storage system is used with photovoltaic generation and wind power generation. The microgrid system at Aichi Institute of Technology in Japan is used as a simulation model. For each simulation, which was carried out by using a power transmission simulator,...
